No detailed investigation of the anatomy has been undertaken in the present studJ; it is aooarent. houever,-that there are considerable differences in the morphology of the it"- d.t*."n'difl.rent members ofthe Salicornioideae. In all speciesthe young internodes have a central stele surrounded by a water tissue which consists of thin-walled parenchyma cells filled with a (usually) saline sap. Around the water lissue are one or more layers of chlorenchymor"ri pa[idde cells Covered by an epidermis. Th-e epidermis- conlains nLlmerousstomata wLich are easily visible with a hand lens; these always have their pores trace arises on each side of the node; aliened transverselv to the stem axis. A single 'leaf' it aivides into three, the central branch passing upwards to\\ards the tip- while tbe lateral branches cuive downwards into the \\ater tissue below tbe node. Each trace branches repeatedly to form an anastornosing network in the-aqueous tissue, the degree of anastombsis vaiying between the different species. In all Australian genera.of the Salicornioideae the'decurrent branches fronr one leaf trace also anastomose with those of the oDposite trace so as to form a complete network around the stem; this union takes olace even ir Pachycornia tria dru wherc the chlorenchyma is absetrt in two opposlte iertical strips whichdelineate the apparent decurrent foliar tissue. The ultimate branches of the vascular network terminate either as simple vascular strands or as club-shaped clusters of tracheids (tracheoids) situated just beneath the chlorenchyma. The former is the case in Pachycornia, Sarcocornio, Scletostegia tenuis, ard Halosatcia indica, while ih" luttat occurs in Sclerostegis arbuscula, S- discttticulqta, Tegicornia and mosl species of Hqlosarciu. De Fraine (Dl2) stated that iL Salicorniq the vascular network arising from one leaf-trace does not anastomosewith that of the opposite leaf-trace, a situation which is contrary to that observed in Australian members of the Salicornioideae and is also contrary to the observations of Fahn and Arzee (1959) on speciesof Atthtocnemum, , ittd Sqlicornia. In the branches of all three traces the phloem tissue faces towards the outside of the stem and the xylem the inside. The palisade tissue normally aonsists of two or more layers of cells which may be sharolv differentiated from the aqLreoustisstre las in Sar.ocotnia) or may merge into it throush a zone of cellsof an intermedjatetype (as jn H halocnemoides).In one species compiex both the stele and ths tissue of the palisade layer differ markedly from that found

\n Sarcocornia, sclereids occur in the palisade tissue (Fig. 2)j these may be evenly thickened or they may have a spiral thickening. Sclereidshave not been observed in other Australian Salicornieae, but they do occur in both species of true . i.e., A. glaucum (Delile) Ung.-Sternb. and in A. subterminale (Parish) Standley which are respectively Mediterranean and North American in their distribution. Inflorescence:A detailed discussion of the inflorescencein the Salic:ornieaewill, it is hoped, be the subject of a future paper; for the present it is sufficient to indicate that it consists of decussateaxillary clusters of flowers, each cluster being sessilewithin a common bract; there are no secondary (or bracteoles). The axillary clusters are in most species arranged in a spike-like structure and the whole then called a pseudo-spike (although actually a thyrse). In several speciesof both Hulosarciq and Sclerostegiathe spike very soon becomes intercalary in position through vegetative growth at its apex; it may then eventually have the appearanceof a normal branch. A few species,e.g. Tegicorniauniflora ?,nd Sclerostegiameclullosa, have the llowers (or flower clusters) in the axils of "foliage" and no obvious compound inflorescenceis formed. In the majority ofthe Sqlicornieqethe axillary clustersare three-flowered. Each cluster has generally been accepted as constituting a cymule (a dichasium); due to the congested arrangement of the flowers, however, and the fact that they are sessileon the inflorescence axis, the vasculature of the cymules is difficult to determine. ln Halosercia lepidosperma (in which the verticils are relatively widely separated)it is apparent that an aiillart stele composed of many vascular strands forms a dorsiventrally compressed,somewhat globular reticulum and terminates in the central flower of the cymule (Fig. 3). It gives rise to a pair of smaller lateral steles which terminate in the lateral flowers of the cvmule. Each of the steles gives rise to a (bract?) trace on the abaxial side of their respective flowers, and also to a pair of lateral (bracteole?) traces, while the traces themselvet divide to form a pair of club-shaped spurs or tracheoids (the possible nature of these traces is discussed later). Since the vasculature of the axillary flower cluster consists of a central and a pair of lateral stelesthe classical view of its structure being that of a cymule is accepted. ltr Tegicornio uniflora only one flower is presentwithin each of the leaflike bracts (Fig. 4). This flower is served by an jnflorescence stele which terminates in the flower and gives rise to a pair of small globose lateral steles that are embedded in the axial tissue below the base of the . These lateral steles are presumably homologous to the lateral steles of the cymule vasculature in Hqlosarcia and therefore it is probable that the solitary flower it Tegicornia is the result of reduction from a three-flowered dichasium. In Surcocorniablaclriana and S, quinquefiorafive or more flowers are found in the axil of a bract. This cymule is similar to that found in Halosarciq except that each of the lateral branches of the cymule stele gives rise to a monochasium (in fact a drepanium) composed of from two to severalflowers. 'Ihe Flo-'ers: flowers are surrounded by succulent bracts or leaves and in some cases are completelyhidden by these. The perianth is gamotepalous,at leastin the bud, and bears 2 4 terminal lobes. The number and position of these lobes is normally constant within a . In Sqrcocornia there are two lateral lobes, an outer adaxial lobe and usuallyan abarial lobe (nhich may be very reduced);in Halosarciathere are two lateral Iobesand an abaxiallobe which may be either insideor outsidethe two laterals;in fectu- cornia lherc are two lateral lobes: in Tesicornio l]nercarc two lateral lobes and an inner abaxial lobe; in Pachycorniathere are t\,\,o lateral lobes; $hile in Sc/erostegi.lthere are two laterallobes with or without an inner abaxiallobe.

The imbrication of the lateral lobes follows a regular pattern; the situation can be most readily observed in Halosarcla where the flowers are always in triads and, depending on the species,the outer florets always have one or other of two possible types of imbricaiion. In some species,e.g. H. halocnemoidesand. H. pergrunulsta ihe outer fiorets usually have the outer lateral lobe overlappingthe lobe nearestto the central floret (Fig. 5C D), in others. e.g. H. inJica the reveise iithe case(Fig. 5A-B). The central florei h-asits imiriic- -.t

Taxonomy

When Linnaeus wrote the first edition of his SpeciesPlantarum (1753) he recognised only one genus, , in the group here referred to the Salicornioideae. Robert Brown (1810) was the first person to describe a membet of this subfamily from.Australian mater\ai (Salicomiu qrbttscltla). at the same time he recorded S. rzllca Wiltd. as being pr_esentin.Australia although the specimenshe referred to this nane in fact belonged to otner specles.

In the first half of the lgth century several genera were described as segregates,or as close relatives of the genus Salicornia, and into three of these were placed speciesbased on Australian types, or speciesthat had been recorded from Australia. The genera with Australian representatives were Halocnemum Bieb. (1819), Sqrcathria Raf. (1837), and Arthrocnentui Moq. (1840). A non-specialist, working with very imperfect material, has difficulty in assessingthe merits of the different genera, and it is not surprising that Bentham (1870), when writing up lhe Salicornieae for the Flora Australiensis, chose to recognise only one genus. Saliturniq; he noted that the material available to him was unsaiisfactoryand that living plants should be examinedin order to obtain a proper appreciation of taxonomic affinities. Subsequently J. D. Hooker (1880) described two furlher genera, Tecticorniq and Pachycornia, in both casesbasing them on a single Aus- tralian species; he also recognised the presencein Australia of the genus Arthrocnenum, in which decision he was largely following the revisions of the Salicornieaeby Ungern- Sternberg(1866, 1876). The circumscriptionadopted by J. D. Hooker for Australian taxa was acceptedby Volkens (1892)and in a modified form by Ulbrich (1934). The onlv nerson after Bentham to revise the Australian Salicornieae as a whole was J. M. Bla;k'(1919) who distinguishedthe salre geneia as those recognisedby Hooker. Black noted the importance of the seedcharacters when circumscribing speciesbut unfortunately many type specimenswere not available to him and the material he studied was seldom in a condition suitablefor critical analysis.

Type species: Sclercstegialerur (Benth.) P. G. Wilson (Salicornia tenuis Benth)

Dwarf sftraDs,seemingly lealless,glabrous; branches when young of articulated cylindrical to sphericalsegments (intemodes) which are cup-shapedto twolobed at apex; segmentssuccrilent, the fleshy outer portion ultimately shrivelling and falling away from thi woody axis. Inflorescenceeither a spikeJike thyrse consisting of triads of flowers (cymes)immersed in the axils of eachlleshy bract, or of triads dispersedamong the branch segments;bracts free from each other or united in oppositepairs. F/ou'ersdimorphic, hoiizontal to almost verticai in positiol, the central one of the triad hermaphroditeand the lateralones male; perianthgamotepalous, membranous or 11eshy,with a pair of laterally placedimbricate lobei on the anterior (abaxial)side of the oriflce and sometinresa small abarirl inner lobe; solitary (abaxial in hernraphroditeflower); style short and stout, passing into the ovary; stigmas 2, narrowly triangular, papillose. FtLtit: periaflt]:' remaining membranous or, when originally succulent, becoming sbrivelled; pericarp firmly crustaceousor woody. Secrlovoid; tesla thin, smooth or faintly granular over the embiyo; embryo straight or slightly curved with the radicle inferior; cotyledonscon- duplicate;perisperm copious. lateral.

Five species,all endemicto Australia (includingTasmania).

Origin of the genetic name: from the Greek words scleros (hard) and sl(€os (shelter); refering to the hard pericarp.

The genus Sclerostegiamay be distinguishedfrom the other menbers of the Sali- cornieaeby a combination of two characters,(l) the dinorphic flowers,the central one of the triad being hermaphroditeand the lateral ones nrale,and (2) the straight or only stightlycurved embryo rlith copiouslateral perispern:. The first characterby itselfclearly difr'erentiatesit froni all other membersoflhe tribe exceptfor Pqchycornia:this genusis distinguishedby its annular embryo and by its unique vegeiativecharacters.

Sclerostegiatexuis, S. metlulktsa, and S. ruonilifornis possessmembranous which persistin this conditioneven when in fruit. In thesethree closely related species the flowers are nearly vertical in position, with the apertures(which are dorsiventrally flattened) at their summit. The aestivationof the perianthlobes is not clear; in some flower buds studied there was a pair of laterally placed conduplicatelobes (with each of the lobes over-lappingon one of its margins and under-lappittgon its other); in otherflowers only the imbrication on the abaxial side of the perianth could be distinguished,the adaxial lobing beingeither absentor not apparent. ln all casesonly the aestivationof the central hermiphrodite florets was noted iince that of ths lateral florets is difficult to observe. ln S. crrbusculathe perianth is succulentand fused to the upper bract but the flowers are otherwise similar to those ofthe preceding three species. In S, tlisqrticulata the flowets are almost horizontal, the perianth succulent, and the aperture on the outer truncate face. In this casethere is a pair of large lateral imbricate lobes ald a smaller inner abaxial lobe which links the lateralpair together.

In all speciesof Sclerostegiathe pericarp becomes hard and completely enclosesthe seed rvhich has only a thin testa. ln S, monilifbrntis, S. medullosa, and occasionally in 'spike' S. orbuscula,the (or fertile branch) continues growth vegetativelyand the shrivelled bracts eventually become sloughed off along with the old flowers and fruit. In S. tenuis the spike-axisalways undergoes thickening and lignification. The steleof this axisconsists (in the mid inlernodal position) of two setsof vascularstrands, one set on each side of ihe transverselyplaced alis (seeFig. 14F). Lignilicationand eventualsecondary thickening of the stele results in the forrnation of two opposite vertical bands between the pairs of triads (the bands beirrgtlrerefore opposite and decussate,changing their position at each node) causingthe fruit to becomemore and more deeplyimbedded in the spike axis. As the steleundergoes this thickening the woody pericarpalso grows in thicknessalthough not so markedly.

Sclerostegia disatticulqta exhibits little regional variation apart from that which might be expected from the same speciesgrowing in diflerent environments. However, at jimba Jimba, in the Gascoyne River area of , is found a variant with more deeply lobed articles which, with the bracts, are prominently denticulate on their margins(Wilcox 158and Gardner 614l). The speciesmay be recognised by its slender spikes with free opposite bracts, and bv the manner in which the spike breaks up when mature into single bracts and compact tiiads each of which contains a single seed. The specificepithet has referenceto the general disintegration of the mature infructescence.

Much branched s/rrab to 2 m high with ascendingbranches. lrlicler slightly glaucous or dull green, obovoid, ca. 5 mm long, shortly lobed, entire. Spikes terminal to both main and lateral branchlets (sometimes sessile),of 2 6 articles, slightly torulose (articles laterallycompressed), succulent; bracts shortly lobed, united in oppositepairs and almost enclosing the flowers. F/orers ascending,intimately fused to each other and to the upper bract, free from the lower; lateral flowers (these occasionally aborted) male and smaller than the central hermaphrodite flower. Perianth fleshy at lateral margins and apex, membranous abaxially with the aperture at or just below the apex on the outer face; lobes 2, lateral, rounded and overlapping but becoming obscure with emergenceof style and anther, sometimes also with a small abaxial lobe. Otary fused along vertical length of spikeaxis, passing distally into a short stout style; stigmasnarrowly triangular.

Sclarostegiantonilifitrll?,s resembles the western variant of 'S.lerlis which was described by Ewart and White as a distinct species, Salicornia donqldsonii. In S. monili/brmis the habit is more branchedand the articlesare obovaterather than cylindrical;the scarious margin of the lobesis also lessprominent. The main distinctionbetween the two species, however,lies in the fruit: in S. lrt?r/sthe pericarpbecomes woody, fuseswitb, and becomes immersedin, the enlargedwoody spike axis,while rn S. uoniliJbrn'i.sthe pericarpis thinly crustaceousand does not fuse with the spike axis which at first remains slender' The bracts of the latter speciesdo not shrivel but become pithy, retain their spherical shape, and then renain around the fruit while the spike tip continues to make vegetative growth. The bracts disintegrate with age and are eventually sloughed ofl with the enclosed fruits. Sclercstegiaarbusculo is also sinrilar to S. mo ili/brmis but may be distinguished by its feshy perianth which is totally fused to the upper bract. Intergradation between thesetwo speciesis discussedvtder S, qrbusculo.

J. M. Black (1919)noticed that the seedsin one he examinedhad rotated 90' relative to the inflorescenceaxis. Material I have studied suggeststhat while rotation sometimesdoes take placethis is not usuallyas nuch as 90', and is presumablya passive responseto the thickening of the axrs. Lectot!-prf cation: Bentham (1870) cited four collections with his description of Salicornia /?,?ri.tas follows: (l) Victorian Expedition; (2) Mitchell; (3) Howitt's Expedition, and (4) McDouall Stuart's Expedition. The lectotype was selectedby J. M. Black (1919) as being the specimencollected on the Howitt Expedition (MEL 71381). The specimen (in herb. K) from the Victorian Expeditionis conspecilicwith the lectotype. The collection from the Major Mitchell Expedition("Irterior of New Holland, 1838",herb. K) is Sarco- cornia quinquefora(Ung.-Sternb.) A. J. Scott. The sheetat K of the collection made on McDoual[ Stuart's Expedition containsthree specimens,one being Halosqrciahqloc- nemoidessubsp. lotlgispicqta P. G. Wils., a secotd H. pergranulqta ssp,ekngataP. G. \Nlls., and the third a vegetativ€ fragrrent of another (unidentifiable) Halosarcia species. The description drawn up by Bentham combined in it the features of the various collections seenby him.

J. Keighery1829 (PERTH);ibid., 16Jan. 1979, C. J. Rabinsonand, J. M. J(rc, (PERTH),from several plants. Map 5. Hqbitat: Saline sand on margin of salt lake. This taxon is recordedfrom a singlepopulation that is statedby one of the collectors (C. J. Robinson, pers. comm.) to cover many hectaresof saline soil. Robinson also observedwhat he consideredto be the sameplant in a neighbouringarea, but no collections were made. Within the population there is variation in vegetative morphology, in in- florescence shape and structure, and in floral morphology. The plant is anomalous jn several ways in that it does not conform to the structure found in any of the recognised samphiregenera. In particular the following charactersmake it unique within the Sali- cornioideae:(l) The terminal (and often the penultinate) pair of bracts are free from each other, their margins are often infolded, and they are attaclred to the axis by a small base; (2) The spike often ends abruptly in this terminal pair of often llorver)essbracts; (3) The bracts are sometimes shortly 3-lobed; (4) The axillary cymules vary in their flower number from 1-3; (5) The lateral flowers of a cymule are usually female and sterile, or they may be vestigial and representedby a very reduced perianth. A further peculiarity which has not been observed in other speciesis that the spike sometimes appears to end in a terminal flower which is presumably axillary to one of the terminal bracts (while the other bract is sterile)and becomesdisplaced to occupy a terminal and axial position (Fig. 18 Ac). ln its general morphology, its flower structure and in the sculpturing of its testa, this plant is similar to Tegicornia ttnifora, while the cymule character, the sexuality of the flowers, and the nature of the inflorescenceare reminiscent of the genus Halosarcis. The variation in generalmorphology fould within the population suggeststhat this plant is of hybrid origin, a suggestionwhich is supportedby the irregularityof somespikes and the high degreeof sterilityof the flowers. ln additiol, n]ost of the seedobserved appeared to be imnature and to have stoppedgrowing at an early stage;this is apparentfrom the slightly decomposednature of the surroundingtissue or of the seeditself. Further field work is required before a conclusiol can be reachedas to what species might be involved in producingthis populalion but, as suggestedearlier, it seemsprobable that the plant is a hybrid bel\\ee\ Tegicornia uniflora and a speciesof Halosarcia. At presentit seemsunwise to give the putative hybrid a name, sinceits parentagehas still to be investigated, I therefore refer to it by a formula'. Habsarciq sp. x Tegicornia unifora.

H.ilosqrcie and other genera The two characters which most obviously distinguish Hqlosqrcia from Arthrocnemunt (i.e. absenceof both sclereidsand the adaxiallyplaced stamen) are of fundamentalimport- ance and suggest that these genera are not closely related. However, the characters which distinguish Helosarcia from Sclerostegia,Pochycornia, Tegicomia and Tecticomia, although relatively obvious, relate to organs which tend to be plastic in their morphology. For this reason I consider that these five genera are closely related and, becauseof their virlual endemism,that they have evolvedfrom a common ancestorwithin Australia.

_The flowering spikes of this speciessoon become intercalary due to vegetative growth at their_apex. On the maturation of the seed the bracts, perianth, and pericarp become dry and thin; eventually the fruitlets tear away from the spike axis to expose the seed which is released. The vegetative and fertile articles have a noticeably fimbriate margin from which characLer1fig specific epither i. derived.

While H.fmbriata in its typical state has a very distinctive appearance,two collections, that of Mqslin 735 and llilson 6492, are intermediate in morphology between this species and H. halocnemoldessuggesting that introgression does occur between the two taxa. 'tears' - - Of those speciesof Halosqrcict ir which the perianth away from the axis, ,1L .fiybyian is probably most closely related to H. Talocneruoides,for iheir seeds are very similar; in addition, in both speciesthe perianth has a small inner abaxial lobe; howevei, the apex of the perianth tn H. halocnemoidesis truncate whereas in H. fimbriqts it rs dorsirentrally ff artened.

Sprkes terminal; bract pairs resembling the vegetativeafiicles but shorter, ca. 4 mm long, becoming cup,shaped with age. F/oweri hermaphrodite, free from each other and from bracts, ca. 3 mm long, steeply ascending, distal half dorsiventrally compressed and slightly winged, apex jusi expoied. Perianth thin (at least when dry), terminal margin rounded to acuminate;lobes two, lateral and conduplicate, imbricate, thin and soft in frrrit- Utricle ellipsoidal, papery, membranous towards the axis; style with hard base- Seedovoid, 1.0 mm longftesta'very thin, pale brown, concentrically granular over embryo otherwise smooth, Fruitlets eventnally tearing away from axis at base.

The nature of the perianth in H. nitida is interesting in that it is intermediate in structure between the type found in E. undulqta and that found ttr H. halocnemoides. ln the material included in this speciesmay be found flowers with only a pair of terminal conduplicate lobes, ?nging to flowers with imbricate lobes covering the orifice on the abaxial rounded surface but extending to the adaxial; in the latteicase a small inner abaxial lobe is present. In those specimenswith the conduplicate lobes the imbrication is of the type found in H. undulata (the lateral florets having the lobe nearestto the central floret overlappingthe farthest away). while in those specimenswith the imbricate lobes the imbrication is of the type found in fL halocnemoidei(the lateral florets having the lobe nearest the. central floret underlapped by that farthest away). Some specimensfas might Deexpecteo, have an lndehnltelmbrrcallon. '01113?

It can usually be recognisedby its dull green or glaucousappearance and by the unevenmargin of the spike; on drying it frequentlytakes on a dark grey colour. There is considerableregional variation in the floral morphology and in the general appearanceof this subspecies. ln Western Australia the lower perianth lobe is large and obvious, both in the fresh and dried condition; in South Australia it is relatively small (about one third the width of tbe perianth) and thin, its position being sometimes within and sometimesoutside the laterallobes, while in the dry stateit may not be immedi- ately apparent and with age appears to become fused with the underlying perianth tissue. Around Adelaide is found a variant in which the seedis ovate (rather than circular) with the central region of either side un-ribbed. This variant rangeseastwards into Victoria and gradeslocally into the typical variant; it is also found jn Yorke Peninsula. In New South Walesis found a variant with slenderbranches and spikes;this is similar to a plant found in Yorke Peninsulaand in both caseslooks differentto the tvDicalvariant which is found in therame general area. The subspeciespergranulcttq grades northwards in South Australia into both subsp. elongata and stbsp. divaricata, although the latter two subspeciesappear sometimes to retain their distinctiveappearance even when growing in areaswhere the two occur. In coastal New South Wales it appears to grade northwards into subsp. cpeenslctnclica. Plants which are evidently hybrids between H. halot:nenoides subsp. halocnemoicles and H. pergranulata stbsp. pergranulala have been collected at various localities through- out the overlapping ranges of these two taxa. These putative hybrid plants frequently exhibit defornritiesand sterility of flowers the ovLrleseither not developingor the seed neverreacnlng matufl ty. Plants which are probably hybrids between H. pergrctnulcrlctand Sclerostagiaarbuscula have beencollected in Port Phillip Bay. For furtber conlmentsee under the latler species. On the north coast of WesternAustralia is found a variant in which the flowers are adherentto eachother and to the upper braat. lt is an €rectplant quite differentin appear- ancefrom sttbsp.queenslanditzr which grows in a similar habitat on the Queenslandcoast. In the flowering slate it is very siniilar to H. indica stbsp. leiostachla and in fact the two may be found growing togetheron the coastalmudflats. Possiblyfor this reasonit has been very seldom collected. The two collectionsseen of this north-coastvariant are as follows: WestefnAustrilia. Wyndham,A. S.

This subspeciesappears to contain three variants but these,with lurther collecting, may be shorvnto be representativesof a continuous cline running around the east and north-eastcoast of Australia. The variants di1lerin the degreeof fusion of the flowers with each other and with the upper bract; in the variant found near Townsville (whicl.t includes the type) the flowers arc free from each other and, at their distal margin, fron.r the upper bract (at least when young); in the southernvariant (Brisbaneto Rockhampton), the flowersare tolally fusedto the upper bract (the epidermisbeing continuousover both organs)and to each other in the distal half. A singlc colleciionfrom Burketowr in the Gulf of Carpentariahas spikessimilar to the southerr \'ariant but with the flowerstota]ly fused together. Plants fronr all localitiesoccupy a sin.rilarhabitat (coastalmudflats or mangrove swamps)and have a virtually identical vegetativeappearance and habit; for this reason it does not seemprolltable to trrakeformal laxonomic divisions within this subspecies. Tlrere is no indication that subsp.queenslondica grades into the inland subspecies nor does it appea-rto hybridize with other Halosorcia speciesrvhich occul in the same area and habitat, but it nay fornr a clinal relationshipwith the coastalvariant of subsp. peryra ulatun which occurs in southern Nerv South Wales, a supposition that again can only be confirmedor otherwiseby further collecting. lt may also gradewestwards along the north coastof Australia into the variant of subspeciespeigranulate fotnd on the north coast of WesternAr.rstralia; here tbe plants are erect,with the llorets somewhatadnate (but not fused)to eachother and the upper bract. In none of the collectionsexamined have any fertile stanens been seenand, in fact, I a study of material which is at a stage,or in a condition, suited to investigationhas in all casesshown that the flowersbear a staminodewhich consistsof a nrinutevestjge about t 0.1 mm long.

'7' L Hctlos.trcie doleiformis is closely related to, and in some situations sympatric with, .R H. pergranulata. lt may be readily distinguished from the latter species by its barrel- N K shapedarticles which becomepithy witb ageand rctaintheir form, by its smooth attenuate spikes,and by the ciliolate margin to the arliclesand bracts. In the mature fruitlets of H. pergronulatathe perianth either remains fleshy and eventuallyshrivels or it becomes SI lirmly chartaceouson the outside and retainsits deltoid outiine (from above),in either CI case the fruitlets fall arvay from the spike axis. ln H. doleilormis the perianth becomes lr dry and pithy, similar to the bracts in textLrre,the whole spike being brittle and readily ir fragrnenlingbetween the articles. The seedsof the two speciesare virtually identical. II

Specirrenswhich are ilternrediate in forn] between H. dolei/brnis and H. peryrunulutt ol have been collected;examples are as follorvs: Goomalling, T. E. H. Aplin 714; 8 km S th of Coorow, A. S. George2310; 15 kn E of Wagin, P. G. Wilson8270 (all herb. PERTH).

The specificepithet refers to the barrel-shapedappearance of the dry articles. fc The flower of H. cloleit'brntisresembles the soulhern Western Ar"rstralian variant of in H. pergrafiulatq(i.e. in having a large rounded outer abaxial lobe), and therefore,con- ol sideringthe virtual identity of the seedsof the two species,it seemslikely that the two ,s planls have arisenin this region from a common ancestorin WesternAustralia. As is th noted elsewherein the text, the forn taken by thc llower of H. peryrcnLlalain other areas tr( of Australia differs considerably from that found in H. doleilbrnis. St

Australia this is absent (or is extremely minute). In Western Australia plants of 1L t syncarpa with very different aspect but with the same fruit type can be found growing l together without any apparent sign of introgression, whereas plants gathered from the t total area of its distribution so vary as to cover the entire morphological spectrum. Much 'syncarpa' critical field work is needed before the complex can be understood. The specific epithet refers to the lateral union of the fruitlels. t f 17. Hafosarcia undulata P. G.

Halosarcia undulata may be recogniscd by its sessile,broadly based, lateral spikes and their short markedly undulate bracts. It is probably most closely related to FL syncarpa which may be distinguished by its predominantly intercalary fruiting spikes and by the lateral fusion of its fruitlets (free in 1L unclulata). The fruitlets of H. unclalata are usually very strongly dorsiventrally flattened towards the apex but in some variants they are more obtuse, in which casethey are similar in shapeto those foundin H. pruinosa. In the latter species,however, the perianth is muricate on the outside.

This speciesis noticeable becauseof its large pruinose articles which exceedthose of any other speciesof Halosartia. lt is evidently most closely related to H. pruinosa and H. undulqtq as is suggestedby the similar fruits. I

The old spikes appear to remain attached to the plant for severalyears and presunrably a fall only with the decay of the dead branches. The frLritlets are tightly enclosed within I the cup-shaped bracts and are securely held in place by a flange on the underside of the n bracts.. Evidently, therefore,the seedis releasedonly after the decay of the bracts and peflantn. 1 c The size of the articles in H. bulbosa may be partly a responseto the particular soil 9 in which the plant grows for rvhen transplirnted to non-saline sandy loam it develops narrower branchlets. However, the other Hqlosarciq species found with H. bulbosu had articles of normal size; these species were H. halotnemoides stbsp. halocnemoides, a H. pergrunulata srbsp. pergrufiL atq, and H. pruinosa.

Bennett3123 testa This sub-speciesis typically a sub-tropicalplant and is relatively common in the bet\\, southernportion of Australia south of 26' latitude. It occasionallyoccurs in association cells with strbsp. leiostachya in more northern localities but here often appears to be a recent Dert arrival since it may be only representedby isolated bushes. Towards the north it grades gro\\ into subsp.Ieiostachya and with many collectionsit js not practicableto designatethen toa as belongingto eitherone sub-specieror lhe other. tidal wrin Sub-speciesblrlers exhibits considerable plasticity of form; ir particular the spike the 1 may vary greatlyin size,shape and texture. The sizeis much dependenton the €nviron- furtt mental conditionswhich when satisfactorycause the spike to becomemuch longer than the c normal. The corkinessof the spike increaseswith age but the texture is obviously also dependent on other factors. The fully mature fruiting spikesbreak up in a mannersimilar to thrr describedunder :'::: subsp. inclica, but immature frr.riting spikes (those which have not assumed a dull pale i. ;: fawn appearance) of both subsp. bidens and stbsp. leiostathya will often suell up and ;"{; disarticulatewhen placed in water. This reaction is due to the gelatinousnature of the ;;'; cellcontents ofthe bract tissueand the perianth. A simiiarreaction has not beenobserved in anv other soecies.

Type species: Sartocornia perennls (Miller) A. J. Scott (Sctliutrniaperennis Miller). About l6 speciesthroughout the world; three are native to Australia, two of wirich are endemic. Origin of name: Fron the Creek word sar-r,flesh, and the Latin word corru, horn, referring 3 to the succulentnature of the planls, the shape of the leaves,and with allusion to the s gents Salicornia (cf. the name Pachycornia). B The genus Sarcocorniq includes speciesrvhich were referred to Sqlicornia by Ungern- s Sternberg(1866, 1876), Volkens (1892), J. M. Black (1919),Ulbrich (1934),and by authors d of recentAustralian Statefloras. However, Moss (1954),T61ken (196?), and BalJ(1964) treated thesespecies as belonging to the genrs Arthroc eml.//7?,a rnove that was accompanled by a misinterpretationof both Standley's(1916) and Ulbrich's (1934) lectotypilication ; of that genus. This lectotypificationrelates back to Ungern-Sternberg'scritical assess- s ments of the genera within the Salicornieae. He recoglised that Moquin's orjginal L descriptionof Arthrocnernumencompassed species belonging to disparategenera and he A effectivelyexcluded all but three taxa, i.e. l. fruticosum var. nlocrostachyur (Moric.) T. Moq. ( , l. glaucum(Delile) Ungern-Sternb.),A. inditunt(Willd.) Moq., and A. arbtrsctrlq tr (R.Br.) Moq. (the last specieswith a query). P. Standley(l914) pointedout the conlusjon D rvhich existed in European floras over the use of the names Selicorniq and Artfuocneftum 2 and later (1916)lectotypilied the latter genus or1A. /niicosnn Inon (L.) Moq.l Moq t, (: A. glaut:utt). This lectotypificationwas acceptedby Ulbrich (1934). Unfortunately ar both Moss and Ttjlken apparently misunderstoodthe inteltion of the earlier authors and consideredthe typeto be A. fruticoslr?s.str., a movewhich ran counterto the intentions of Ungern-Sternberg,Standley, and Ulbrich (see also A. J. Scott, 1978). The genera a Salicorniq and Arthrccnenttunas previously understoodtogether contained fivs distinct 5 groupswhich are hererecognised as separategenera, the additionalones being Sarcocorniu, v Scle rost eg i o and H qlosqt ci u, f(

The name Arthrocnemun heptiflortrnt Moss (1954) was publislred posthumouslywhich could acaountfor the confusionwith its earlierhomonym published Moss ex Fourcade in 1941, also after Moss's death. Moss (1954) stated that the H by "S. lo name A. heptifloruizwas a'nom. nov.'; in his synonymy he cited three names,viz. austrqlisSo1. ex Forst. Prodr. 88. 1786 (nomen nudum)i S. indica Hook. Handb. N.Z. pachystachyaBlack Fl. S. Austral. 2. 208 f.l. 1924.non Bunge D Fl. 233. 1864non. Willd. S. tr ex Ung.-Sternb.". Moss* died in 1930and the editors of his manuscriptwere evidently r.rnawaiethat Ulbrich (1934) had already provided a new name for S. pctdrystachyaBlack and that Bentham (1870) had validly published the name S. attstralis (.basedon Solander's 'nont. o' manuscript name). Moss, in calling his name a nov.', and in citing the type as Is. being the Forster specimenfrom ,lvas evidentlyintending a nomen novum for S. australis So1.ex Forst.f., though it is unclear why he felt this required a new name. There is the possibilitythat he was aware of Bentham's'5. qustruli;' and assumedit to E. be basedon an Australian plant. He was, therefore,providing a new name lbr the New Vt Zealand entity. In any case, the name A. hepti/lctrum (1954) is illegitimate being both 10 superfluous and a later homonym. Salic:orniapachystachya Black is distinct from the Zoaland species and is a nomenclatural synonym of Sarcocornia blackiqna. In T6 New Nt his paper Moss also cited specimerrsfrom Sottth and East Africa; these are referled by Tdlken (1967)to A. deatmbensTolken (: Sarcocot ia decumhens(Tolken) A. J. Scott). So of (1954) different The nane A. australasicumwas misappliedby Moss to atleasttwo W species. The New Zealandand New Caledonianspecimens cited belong to S. quinquefora 3t while the African specimensbelong to Sarcocorniq decumbens(Tolken) A. J. Scott (see Tdlken, 1967). The type of ,4. austrclasicutllwas statedby Moss to be a Robert Brown ltl specimenfrom the East lndies in herb. BM: the type is, bowever,a specimenof unknown b( collector in herb. P; the name has been transferred to Tecticorniq 4s T. austrulasirc (Moq.) in quite (see 1972). P. G. Wilson, a species diflerentfrorn thoseconsidered by Moss Wilson, IN Robert Brown applied the name Sali(:ornie intlica Wt1ld. 10 the speciesconsidered Ti here and his application was followed by both Richard and J. D. Hooker. Moquin (1849)recognised a misidentificationby Brorvn and consideredthat the latter's specimens hz (1853, probably belongedlo HalocnefiLtffioLtstrulusicLlm Moq. However, J. D. Hooker o{ (and 1860),who evidentlydiscussed the matter with Brorvn,adhered to a broad obviously th incorrect) concept of the species. Brown (1810)appears to have based his description of S. indica on material of Sarcocornid ? quinqueflorafrom Fowlers Bay, South Australia (cf. his Flora manuscriptat the British Museunr),but his cited distribution of the plant m encompassedspecimens or observationsof severaldiflerent species. ot iL th Key to subspecies It sp Plant decumbent (or shrubby): spikes slender; seed with slender often rurcinate la. subsp.quinqueflora of trichomes .... na Plant caespitose;spikes shortly cylindrical; seedwith short acutetrichomes ...... qu lb. subsp.tasmanica So Ol * The 1954paper by C.

Tijlken (1967)noted that the abundanceof sclereidsin the palisadetissue was often relatedto the salinity of the soil; the greaterthe salinity the more numerousthe tracheids. I have not observedthis correlation in the Australian specieswhere relative abundance appearsto be determinedby geographyrather than ecology.

Tdlken (1967) recognisedthat S. quinque.floradid not occur in southern Africa, as had been stated by Mois (under S. cntstralis)and he described the African segment of the'australis' complex as a nelv species,Afihroc emum decunbens. Tolken compared A. tlecumbenswith both S. quinquefora and S. blachiQnaand stated that the latter two specieshad spiral sclereidswhereas in A. decumbensthey were uniformly thickened. As noted above,spiral sclereidsdo occur in a variant of S. quinquefora.but this variant bas not beenrecorded from near Adelaide,Melbourne, or Sydneyand sinceplants fron these areastend to be more slenderthan thosein wl.richspiral sclereidsoccur it is unlikely that such will be found. S. quinqueflorawas described from material that was collected near thesecities and it is thereforeplobable that none of the syntypespecimens have palisade tissuewith spirally thickenedsclereids.

Collectorshave sometimesindicated that specimenswere dioeciousand Black (1919) found S. quinqueflora to be functionally so, the male plants having ovaries which were sterileand smallerthan thoseof the femaleplant. A study of herbariummaterial suggests that the plants of some localities are dioeciouswith the mnle flowers as describedby Black and the female with small stanrinodes,holvever, in generalspecimens bear what appear to be hermaphroditeflowers. It is not clear how this sexualityis relatedto the piant's distribution or whether it is dependenton environmentalfactors. (For a general discussionon this phenomenonsee J. Heslop-Harrison,1957, 1972.) 'fhe Ecology. ecological conditions which generally operate in segregatingS. quinqueflota ald S. blaclcianqare not clear. Both specieswill grow in situationswhich are periodically inundated, wtth S. quinqueflora generally occurring where the water has zLsalt content roughly equivalentto or lessthan that ofthe seai S.trcocorniablackiana, when allopatric with the former species,often grows in areas which are drier for much of the year or are likely to have a higher salt conleni; it will also grow in salineloam which is very dry 1n the summer and here it adopts a bushy rather than decumbenthabit. Where the two speciesgrow together they tend to be virtually identical in gross morphology. It is interestingto note that in WesternAuslralia the variant of S. quinqueJlorawhich has spiral sclereidsis found growing in conditionswhere water stressis likely to be at timesextreme; this anatomical character may therefore be an advantageousadaptation to thesesituations.

Moss (1954) cited the collection 'Black 8' frorn Glenelg, Sonth Anstlalia, as being the type of Salicornia pachyslachya and he listed this name as a synonyn of Arthrocnenunt heptflorttnt. A specimen in herb. AD, collected by J. M. Black on 20 January 1920at Glenelgprobably correspondsto this and has beenselected "sent as lectotype. It bearsa note in Black's handwriting to say that jt was to Paris as no. 3, 30/1/20"; the no. 8 referredto in Moss'spaper may be a copying error for a "3" on a specimenin herb. P. For additional notes on L heptiflorumFourcade (194l) and A. heptiflorunt Moss (1954) seeunder S. qtinquefloro. Morphological Notes, Sqrcocorniq blqckian.t is rather uniform in appearancethroughout its geographical range (but it becones slightly 1rore robust towards the north-western limit). The papillaeon the testaof the seedsprovide the clearestcharacter for distinguish- ing it fronr S. quinqueflora and, in fact, fronr other members of the genus. In Victoria, Tasmania, and South Australia the papillaeare short and rounded, whereasi[ Western Australia, in addition to plants which exhibit this typical form, may be found those in which the papillae are slenderand tend towards the shape of the trichonresfound on the seed of S. tluinqueflora.

In all specimensexamined the palisadetissue had abLrndantspirally thickeled sclereids (fig. 3F) which, in materialfrom much of its range,are usefulin distinguishingthis species from S. quinqueflora (but see comnlent under the tatter). The central fforets of the cynrulesin S. blackiqneare frequentlyin two tiers although the flowers of the lower tier may be vestigial. Old spikesfrom which the llowers have fallen still bear an indication ofthe two tiers in the concavitiesoftheir axes. In the extremervestern limit of its range the single-tiercondition is normal.

Note added in proof

The type species of Arthrocnemum is stated earlier in this artic,le tobe-4. Slaucum (Delile) Un-g.-Siernb. (1876); however, the epithel glaucum dates from 1876 since the iornbination- is based on Salicorniq slauca Dellle (1813), an illegitimate name being a later homonym ol S. glauca Stokesal8l2). Some recent authors (seerynonymy) ha\e therefore usid for thJ same species the name Arthrocnemum macrostachyum (M.oric.) C. Koch (1853) which is based on S. macrostachyaMoric. (1820); however, according to Index Kewensis (1895) an earlier synonym exists, viz. SQlicotnia mucron(ttq I ag. (1817), a name which hai nev6r been accepied bi botanists nor has it been transferred to Arthroc- nemum- rJngern-sternberg (1876j appe'arsto have been th€ first person to suggest the synonymy o{5. mucronati with .l. ftaucum atthough he ciid so with a ouery, which was underitandable sincethe description of the former specieswas based on vegetativematerial. Index Kewensis(1895) . provided the samesynonymy and Moss (l9ll) statedthat he.was following that work. Ii is likely that the later authors did likewise since, in each of those oaoers cited above in which the name Salicornia mucronqla is mentioned (except for that of-Ungern-sternberg), the page reference for the original publication is incorr€ctly given as 58 instead of 53. I am not transferdng Sqlicowit mucronatq to Arthrocnemum in view of the lack of evidence that any workeisince Ungern-Sternberg has looked into its correct applicatio-n. Until such a stuiy is undertaken ifwould appear desirable that th€ name applied to the species in question should be Arthroc emum macrostqchyum. The relevant synonymy is as follows: Arthrocnemum macrostachyum(Moric). C. Koch, Hortus dendrologicus 96 (1853);Zohary, Fl. Palaest. 1 :156 (1966); ftfri ei Rateeb, Ft.
