R. xschulzei (R. conglomeratus x R- crispus), R. xmuretii (R. conglomeratus x R. pulchet), R. xpratensis (R. crispus x R. obtusifolius) and R. xpseudopulcher (R. crispus x R. pulcher).

Species are arranged within the text according to the infrageneric classification which is outlined below. In most casesonly a selection of specimens seen has been listed. Those herbaria from which material was examined are given in the Acknowl- edgements. The study was conducted at herb. PERTH and it is believed that the spe_cimensexamined there included the majority of those currently housed in Aus- tralla.

Geographical distribution and ecology of indigenous species For the iirst time the distributions of indigenous Australian species have been mapped. I am of the impression that except for some areas of south eastern , these distributions are incomplete. This may reflect a certain lack of interest in the genus by collectors within certain areas. I hasten to add, however, that following three months in Western Australia where field work was conducted be- tween Kalbarri and Albany, I was successfulin locating only two indigenous species of Rumex (R. brownii and R. dumosus). Indigenous species are evidently either rare or geographically very restricted, at least in this part of Australia. This experience raises the question as to whether or not R. drummondt'i has become extinct.

Most of the indigenous Australian species are centred in the south-east of the con- tinent. One of the most geographically restricted speciesis R. bidens, a semi'aquatic which is found in freshwater swamps (Figure 11A). Its thick, hollow, creeping rhizome is at least temporarily submerged and from this arise short, usually unbranched . It is known from New South Wales near the Murray River, Victoria, Tasmania and parts of South Australia. Eumex brownrJ is wide- spread in both coastal and inland areas of south eastern Australia but there are scat- tered, disjunct occurrences in Queensland, Central Australia and south-west Western Australia (Figure 13A). This speciesis also recorded for , New Guinea, Timor and Java and it is not known what comprised its original area of occurrence. suorsJncxa5ur{Ettl uaqA|suorJBAJasqoplall ud\o,'{ruulo4 sB IIo.{\SB EIJEqJaq UBIIeJI -sny roferu aql ul uorlBluaseJdarslr ruo4 peSpnt aq uB? ,{Juanbarl sll (eJlaso?aJv' 'ua5qns) Bllaso?aaa g flalrur;ap sI snuaF arll Jo uollP luanbarl lsoru ?r{J 'EITEJlSNY UI UAIIB I€NSEJ 'sarcods 'JrqdJolu^lod ,{lluapr^a pue ?rpJ E sr ueauBJrallpal I lEnuuB ,{lluPuluropard 'BrTEJlsnY ,{faurarlxa uE 'snroqdoFqdfinq xourntl urqltal edersa uapJBS B sluasaJ -dar sarcodsuBJrrJV qlnos sIqJ sa^eaI J]E]]IiES puE s]oirr snoJaqnl qlr^\ JaqruII) P sr (asolaJy ua8qns) s-n?B??r,'esxatuna' €rlun3 Ep uBlsIrJ puE pue1s1q8nop ::rr1ue11y qlnos aql ur spu€lsl IIErus o,{\1 urorJ u,\\ou{ oslB sl 1l lnq EclJaurv qlnos sI eaJE 'V',44 ',{ueqMo url {€8 uet[[IlA I€uortnqrrl.slp uIBuI sJI orooj,{ uqof [q ]sa.\\ 0L 'ra^ru C)l 1€ Ig6I ul para^ocsrpar sE,{\ lI €JJBA aql Jo qlnou.r aql lE slro,'i\ JnoqJeq luuro Surlsrxaraguol ou ^lrlBDol€'aurnoqlal l'puBISI opooJ uroJJpopJoJar lsrlJ sE,{\ 'u'uPtlJaurv 1I BrTBJlsnVoJ A\au sB aJaq palrodar sI suatsa?n{ q}nos aqJ ^rn}uJJ rallel aql Furrnp sra,rtrp ueq8.1y fq €IlEr:lsnv o1 patnporlul lsBI lo JlBrl lautec 'uaar8 sBm sa,cadi srql lBql al.Elntods ,{Eru auo sa^Eel lualncJns leg,tauos 'aEJBI al€d sll puB sa^lE^ pa8ull qslldlnd ualJo sl.r [q uolluolle Jllqnd JerllE 1I puB €rlprlsnv Jo sBoJElsBA JoAopEards sI snrrBJ.Isa^U,{epoJ salJodslJurlsrp ,{lJPalJ "I 's?IJads inq pai11e,{lasolcE snasolg'sB Paureuslur,{11red sB.'{ ltl JaIBI:rt?uauralJ 11 (]1 ]$au € ss sn{J poqrrJsapulruoc IZ6I uI EIIBrlsnY oJ }uBrbrullul Juarar JSou oql oq 'ErsV sulaes lsar!\qlnoS puB BcIJJY-I{lroN Jo s€arE lrasapl[ras puB ].JasaplnoqinoJrll pBardsapr,rsr qf,Iq^\ salJ?dsuEIpuIS-oJEqBS €'(Pso?ary uaEqns)snrJPilJsal xa.lllH '(,$olaq aas) ulaql uaa^\laq Jn))o spliq,{q PIJ'lsolJJeU rol ldaJxa puE raqlaSol i\oJ8 ,{llpuoISpDtosaIJ?ds oserlJ [.rnluaJ lsEI aql Jo.]l€q lsriJ aql ur sral:l'tasfl.lEa aq1 paruBduroJJeaAEq oJ uraassuloJIsuJqo u puP srl/"rJurr'1;t.roJH 'rarlJ[nd aqJ tI'sndsr1J lI'l s "IJaso?arPU salJodsuBauBJJoJlpatr^l puE uBadorng suaIIV

in various directions from Perth, I have seen it practically everywhere along road- sides and on other disturbed sites. It covers huge areas of neglected fields south-west of Capel.

The most frequent speciesof the subgenus Rumex is beyond doubt E. crispus. Its strict habit is very characteristic and is unlike all other Rumex species uccurring within Australia. Rumex crr'spus fruits somewhat earlier than the other species of subgen. Rumex but there is sufficient overlap of flowering times to permit hy- bridization to occur. Probably R. pulcher with its two subspeciesis the third most common alien species of Rumex in Australia where its spread seems to have been favourably influenced by its high drought-tolerance. In the past this alien species was confused with the indigenous fi. dumosus and R. drummondri, an error dating back to Bentham's (1870) treatment of R. pulcier (seesp. no. 9 below fbr further de, tails). Rumex conglomeratus and R. obtusifolius are of only minor importance as aliens within Australia.

Rumex ft.i,merrosepalusTorrey, Botany Mexican Boundary 177 (1858), from the Southwestern United States and Mexico. is recorded in the NSW census (Jacobsand Pickard 1981) as naturalized (sporadically) in N.S.W. and Victoria. It is charac- terized by tuberous roots, somewhat succulent stems without axillary branches, fleshy, lanceolate, acuminate leaves with cuneate base and large, delicate, entire valves lacking callosities. Its taxonomic position within subgen. Rumex is isolated. The large valves lacking callosities are somewhat similar to those of .R. yesicarius. but the latter species is an annual and belongs to subgen. Acetosa. Rumex hy- meno.sepalusinhabits the most arid parts of SW North America and is there Iocally frequent on sandy and sometimes saline soil. For details seeRechinger (193?:89-92).

Hybridization Hybridization occurs frequently between most of the species of subgen. Rumex. These hybrids are usually highly sterile therefore back crossing seems rare and hy- brid introgression is absent. Pollen sterility is easily recognized by the grains either being of more or less unequal size or sometimes clumped together and forming an amorphous mass which is not releasedfrom the anthers.

In nature, hybrids of I?umex may be recognized by their appearance.The primary panicle sheds most of the sterile flowers but the continue to grow and tend to form secondary i'lorvering panicles. Thus the hybrids are often taller than the parents and assume an untidy habit. Additionally most hybrids fail to set fruit becausethe tlowers dry and fall off belbre full development of the valves (i.e. the three inner perianth segments) occurs. The iew fruits which do reach full size combine the characters of the parents in various ways. O1len these hybrid nuts, even if reaching full size,are not viable and can be compressedbetween the fingers.

From the large amount of Australian herbarium material examined, all the hybrids detected, with two exceptions,had European speciesas both parents. The most fre- quent hybrid is E. crr'spu.sx R. obtusrToljus and this has been recognized by collectors in several cases.In Europe it is found wherever the parents grow together and it is evidently the most frequent hybrid in the genus and perhaps the most frequent of any genus within Europe. Rumex crlspus x R, pulcher has only recently been found in south west Western Australia by John Moore and by myself. Occurring also at the same localitl' were R. conglome.ratus x R. crrspus and R. conglomeratus x R. pulcher, 'por.red 3ur1rnr3 puE Suua,roU palrllrrT € r{1r.4dolcruPd Ieur[rJa'l p SurJnpord ',{rBtrlos pu€ poqf,uPJqun urals lso^EolI€sEq Surdola^?p sluBld saJrldars uollcaq a 'alEUrluJal -apur [11ecr1ce.rdsr ssaJoJd8ur]rn{ pu€ SurJe^\olfoql:sauo frEurud aqt dol.ra^o ualJo qcrq^\ secua?saJollur^r€puoJas dol?^ap ol pual l€q] slooqs .{J€llIxP ',{}paT'r?tn8ar surrnpord :sa^Bat T€spq surdolo^ap tou sluptd "::?,1fl"ri?,li"S*": s?r oJur xa&Ild. uaSqns Surpr^rp ur acu€JJodur ,{reurrrd go aJEsralrBJBqf, q},{\oJC 'snue;qns slql ulrllr^\ lsltuouoxBl 'azlplJq,{q eq1 ro; suralqo.rd urPur aqJ Jo aulos osn€c o1 selJads ,{u€ur lo dlrlrqB ar{l qllM rarllaSol 's1J€l ?s?qJ alua€ro^uoc puE rusrTallE.rBdur Surllns -ar'sarJads Jrqdrou.{lod fJaI al8urs p urq:u^\ JnJJo suoll}Burqulo)alqlssod IIB sase3auros uI sarJadslo dnoJg B ol Jo sarcadsalEurs B ol palrulrl aq {eul,'(ar{J 's,{EnasnorJBA ur paurquroD Jo {lalpJBdos rncJo ,{€ul suorl€Jrfrpou asaqJ 'rlldu?l 'adeqs 'Jaqurnu 'e pu€ uorlc?rrp snou€A Jo qlaa] dola^ap so^Ip^ aql Jo suriiJpluoqJ 'AlrsollEc I€sEqB olur poruJoJsuBrl sr puE sualJrql ssal ro arour SoAIEAsarr{l IIB ro auo lo qrrpru aqJ z 'dola,\ap sa^Jau Jo lror!\Jou B pu€ snoueJqurou ssol ro aJour auoJaq sa^lE^ aqJ I :aJpuorJEJrJrpou aAIBA Jo sad.{l urBurooJqJ aqJ ssaJoJdSuruedrl aq1Bur rnp (sa^lp^) sJqaluSosrlluErJad Jauur aeJrlJaqJ Io sJrlsrraltEreqJuorlpurrolsuerl ?r{l uo pasBq sr snuo5qns srql Jo ^ruouox€l o.g.l (unqlede.I uaSqns u,{i^)xaulnu ua8qns urqlr,^ spuarl ^rEuorJnlo^aurelrac paurllno I (q616f .raEurqcou)JadBd .rarlJBa uE uI 'IerJlJrlrE ,{1q8rqeq ()1paraprsuoJ sr Juatu?FusJJBsrqf sa^lBAa]sluap q]r,r sarf,adsSurur€luoc Jaqlo aqt pu€ soAIEA8ur1ru; arrlua rl:Il^\ sarJadsSurureluoc auo 'sdnoJ8 o,,\\l olur (utnqlede.I uorlcas srq) xarIrDU ua8qns papr^rp (lggI) Jausra]I

Distribution. Probably originally spontaneous in Europe and southwestern Asia. Now well establishedin most extratropical parts of the world. Rumex crispus is the most common of the European speciesof subgen.Rumex in Australia.

Rumex crispus,in spite of a moderate range of morphological variability, can eas- ily be distinguished from other speciesin Australia by its t strict and rather dense panicles, its crispate leaveswhich are attenuate at both ends and by its broad, cor- date-rounded,entire fruiting valves of which usually all, but rarely only the anterior one,bear a callosity.

For Synonymy seeRechinger f. 1949a:96.

Perennial. Stems usually 30-80 cm high, t erect, often branching from below the middle; branches arcuate-divaricateand forming open panicles. Basal and lowetmost stem leaves petiolate; petioles usually as long as the laminae; laminae I1at, narrowly oblong-ovate with slightly cordate or truncate bases, up to 6 cm x 3 mm, small in comparison with the size of the plant, apices rotundate obtuse; upper srem leaves be- coming gradually smaller and with shorter petioles and more acute apices. Flower w.horls many flowered, all distant, all (except sometimes the uppermost) subtended by a small short petiolate Ieaf. Fruiting pedicels about the same length as the valves or only slightly longer, articulate at the middle or slightly below. Fruiirng valves 2.5- 3.2 x 1 1.? mm, oblong ovate, entire, all bearing a large callosity which sometimes occupies nearly the whole surface of the valve. Nuts 1.3-1.7mm long, dark brown. (Figure 1A).

SOUTH AUSTRALIA: Mi Lofty RangeNational Park, 11 December1943, J. B. Clelands.n. (AD); Banksof River Torrens,Adelaide, T. J. Smith 2073(AD). WESTERN AUSTRALIA: RobinsonEstate, SW of Albany 35"02'S,117'53'E, K. H. Rechinger 60015(PERTH, W).

Distribution.Europe exceptthe Arctic (in the Mediterraneanthe speciesis restric- ted to the mountains);South-west Asia eastwardsinto the central Elburz Range. Introduced into many extratropical parts of the world and more or Iessestablished in some places. In Australia much rarer than R, crispus, R. pulcher arrd R. congtomeraf,us.

Rumex obtusitoliu.s is a polymorphic species which can be divided into four subspecies(see Rechinger 1932:41-61). The most commonone in Australiaand else- where outside its natural area of occurrence,is subsp. obtusifolius (syn. subsp. agrestr's(Fries) Danser); it has valves up to 6 mm long, all usually possessingthree teeth which in length about equal the width of the valve, the anterior valve only bearinga callosity.Some Australian specimenstend towardssubsp. transiens with slightly smaller valves,shorter teeth and usually all valves bearing a callosity of un- equalsize.

"Hab. 9. *Rumex pulcher L., Spec. Plant. 336 (1753). Type citation: in Gallia, Italia. Veronae."

Perennial, variable in habit. Stems 20-60 crn high, t stiff or angular-flexuose, vari- ously branching often from below the middle (seesubspecies). leaves thickish, com- paratively small, often papillose below, petiolate, petioles usually shorter but some- times about as long as the laminae; laminae of basal leaves ovate-oblong from a cor date base, sometimes constricted below the middle (fiddle-shaped)-see subspecies; stem leaves tew, shorter petiolate and more acute than the basal ones. Flower whorls many-flowered, all distant, all subtended by a small leaf which is not prominent in the uppermost whorls. Fruitrng pedrcels thickish, articulate near the middle or slightly below but not dehiscent, shorter than or sometimes equalling the valves. Valves thick, leathery, variable in shape (see subspecies),4.5-6 x 2.5-4.5mm, with a thick reticulate-foveolatereticulation, usually all bearing a callosity, of unequal sizes, margins variously and grossly dentate. Nuts 3-4 rnm long, broadest below the middle. (Figures 28 and 2C).

Distributbn. Mediterranean region and south-west Asia. Introduced into, and in places well established in, warmer places of the world. Common and locally well es- tablished in America and Australia.

Bentham (1870: 264) did not have a clear concept of R. pulc-treras evidenced by " the following passage from his description: . .. radical and lower leaves oblong lanceolate or almost linear. Pedicels shorter or longer than the perianth. . . Inner segments of the fruiting perianth lanceolate or triangular, 2-3 lines long with a rigid point. . . " These characters do not apply to R. pulcfter but instead to E. dumosus or R. drummonclii. Bentham confounded specimens of the Australian indigenous species,R. dumosus or R. drummondii, with the alien R. pulc-her.This is apparent not only from his description but also from his listing as synonyms R. oxysepalus and R- drummondii. This error has persisted in some publications and herbaria up to the present.

Perennial with vertical rootstock. Stems several, 20 50 cm high, flexuose, repeat- edly dividing from near the base with numerous thin, flexuose branches forming an entangled mass breaking oll near the base and dispersing as a tumbleweed. Basa.l leaves long-petiolale. laminae 10-20 x 0.8-2 cm, linear-lanceolate from a broadened truncate or broadly cuneate rarely subcordate base,sometimes constricted above the base, panduriform and/or obtusely lobed at the base, with coarsely erose crispate margins, apices acute; stem leavesnumetous, similar to the basal ones, gradually be- coming shorter peticilate and narrower and more acute. Panicles (see above). Flower whor.ls (2)ll-4(5)-flowered, distant, loose, nearly all subtended by a narrow leaf. Fruiting pedicels of varying length within one whorl, rather thin, articulate below the middle. Fruiting valves c. 5 x ll mm long (excluding teeth), triangular, attenuate, strongly reticulate; medium nerve not or only slightly thickened, (more or less in- crassate),somelimes forming an elongate callosity (var. dumostlbrmrs); usualll' two strong teeth presenLon the lower part of each side of the valve, the lower one more or less patent, the upper one antrorse, sometimes a shorter third one occurs near the middle. Nuts 2.5-ll mm Lrng. (Figures 2E and 6).

,Rumex durnosu"sis interpreted here in a broad sense as comprising a set of vari ants badly in need of further investigation. Both comparative morphokrgy and cytological studies as well as cultivation experiments are required to elucidate the complex variation patterns observed on the basis of limited fruiting material.

'fhe relationship of R. dumosus to the New Zealand endemic, R. flexucrsusSolan- der ex Sprengel should be reconsidered.Al present I have no N.Z. material at hand for comparison. However, according to my earlier treatment (Rechinger 1935a: 45) the two speciesare relaled by lheir characteristic panicles whose iine, repeatedly div- ided branches form an entangled mass which breaks-off at ground level and is dis- persed as a tumbleweed.

'Ja8urqreu ErlBr?snvur reLun8 H )I 98 Nultsia Vol.5, No. 1(1984) per whorl, its articulation on the fruiting is closer to the base and the valves are smaller on average.There is much variation in these characters within the Aus- tralian material of E. dumosus examined.

Rumex drummondtl is accepted here as a species(see sp. 11 below) but it is noted that very little material of this taxon has been seen. The status of R. drummondii and its relationship to R. dumosus is therefore in need of critical reappraisal.

In my earlier treatment of Rumex (Rechinger 1935a: 43) I distinguished -R. dumosjformis from R. dumosus on the basis of three characters of the fruiting valves: the valves were smaller, possessedlonger teeth and their central nerve was thickened into a callosity. It is now apparent that these characters are not correlated and that there is variation from specimens with valves lacking a callosity to ones where it is quite pronounced. Eumex dumosiformis should therefore be regarded as only a variety (see 10b below).

Distribution (Figure 12A). South eastern Australia.

In -Riunex-stenog/ottis the valves are about 5 mm long (excluding the teeth), rarely 1.5 mm broad near lheir base and prolonged into a long thin very acute reflexed tip; there is only a single tooth at the base of the valve on each side. The collector of the type specimen has named his plant R. crystal,Lru.s Lange; E. M. Canning has tenta tively renamed il as R. tenax. By the few fruits per whorl as well as by the pedicels longer than the valve, the plant, however, is definitely different from both these species;lrom fi. cr1'slallurusit is furthermore distinguished by its perennial growth habit. Several ofher sheetsof R. stenoglottis which I have examined had been named 'f R. dumr.,sr.r.s.he latter is evidently the closesl relative of the new species.Both have in common the repeatedly divided panicle with the branches forming an entangled mass. Ilunrex stenogktttis, however, difters from R- dumosus by the very narrow, lingulate valves bearing a single looth at the base on each side.

Etymologv. The specific epithet is derived from the Greek words stenos (narrow) and g.lossa(tongue), referring to the shape of the tip of the valves.

Distribution (Figure 118). Rumex tenax has an eastern Australian distribution roughly belween 25'30'and 37',15'S and 139'30'and 152"30'E. Most localities are situated west of the Great Dividing Ranse.

As there appears to be considerable confusion between R. tenax and R. crys- tallinus the distinguishing features between these two speciesare given in the table below. Although the name R. fenax was correctly applied by both Beadle, Evans and Carolin (19?2) and Burbidge and Gray (1970),Willis (1973) confused it with R- crys- tallnus. Many Australian herbarium specimens referable to these taxa have until now been wronslv named.

Dist.ribution (I'igure 13B). The new speciesis restricted to the Eyre Peninsula-Flin- ders Range area of South Australia. It occurs at the western end of the range of R. brownii in that State.

Rumex alcockii is closely related to R. brownii Campd. in that the teeth on the margin as well as at the tip of the fiuiting valves all end in a hook and by the lower most floral whorls only being subtended by a leaf. Rumex alcockii is distinguished from R. brctwnii by a number of correlated characters, viz. its vigorous growth, its thick, short leaves,the lower ones on averagebeing only 2.5 3 times as long as broad, its more numerous llowers per whorl (8-15 in fi. a.lcockii,(5)6(8) in -R. brownrl) and its larger frniting valves (4.5 5 mm long in R. alcockii, (2.5)3(4)mm in R. brownii).

Etymc ogy. The speciesis named in honour of C. R. Alcock, Pest Plants Commission, South Australian Department of Agriculture. The segregation of this new species from R. brownil was made possible through an instructive set of specimensgathered by Alcock, viz. nos. 15,10,2309,2524,2585, 2588, 2748 and 4179 (all AD).

Distribution (!'igure14). All mainlandStates in arid/semiaridareas.

Rumex cr.ystallinus,the only annual Australian Runrex,undoubtedly belongs to subsecl.Ma-rittni Rech.f. (193?).This subsectionis characterizedby annualgrowth, small valvesusualll' with long teeth and all bearinga callosity.The distribution of the subsectionis world wide.Each continent has one or severalendemic species. Eco- logicallyall Nlaritimi grow on temporarily flooded depressionsor along riversides. None areweeds.

Rumex crystdlinus has up till recently been confused with E. ,enax which from my standpoint is neither similar nor related. The distinctive characters have been pointed out in detail under R. lenax (sp. 13 above).

This is the first recorded hybrid between two indigenous Australian species of Rumex.

19. Rumex xjohannis-moorei Rech. f., hybr. nov. (=R. brownii CampderS x R. crisp us L. )

Perennis. Caulis erectus, in parte superiore pauciramosus.Folia emarcida. Florum verticillastri multiflori. Pedicelli fructiferi tenuiter filiformes, inaequilongi, in quarta circiter parte inleriore articulati, quam valvae duplo usque fere quadruplo longiores. Valvae ambitu et magniludine variabiles, cordato triangulares, valde inaequaliter calliferae, apice partim quidem t productae, longitudine interdum latiores, margine irregulariter denticulatae. Nux saepesaepius incomplete evoluta.

Typus:60 km S of Jerramungup, Swamp Road, property of R. D. Hurst, on field bor- ders, 8.12.1982,Rechinger f.60063 (holo: PERTH; iso: W).

Rumex xjohannrs-mooreiwas recognizedby John Moore as a hybrid. It was found in association with .Rumex cnspus while R. brownii grew nearby. It is intermediate in habit, is of more vigorous growth and is more profusely branched than E. browrii, but the branches are more patent, more elongate and more flexuose than in R. crr'spus.The pedicels are of very unequal length but in proportion to the valves on average are longer than in R. crispus. The valves are in general appearance more similar to R. crrspus but smaller and of very unequal size and shape and i irregularly denticulale near the base; the callosities are very irregularly developed. The degree of sterility seems to be rather high, a considerable number of flowers have set no fruils at all. in some of them the nuts have reached their full size but usually they can be compressedand seem to be not viable.

R. brownii x R. crispus is the first recorded spontaneous hybrid between an in digenous and an alien species.It is named after its discoverer,Mr John Moore of the W.A. Department of Agriculture (Albany branch), who has undertaken a special study of fiumex in the Albany region. John guided my wife and myself on several ex- cursionsin the Albany region in December 1982.

20. Rumex xschulzei Hausskn. (= R. conglorneratusMurr. x R. cnspus L.) Mitt. Geogr. Ges. (Thiiringen) Jena 3: 68 (1885). Typus; Several syntypes liom Germany: Thiiringen, Ha usstnec-hl (JE).

In habil closer to R. crispus but panicle less strict, flower whorls more distant and at least in the lower half of branches subtended by a leaf. Valves entire, much smaller and especiallynarrower than in R. cri.spus.

Known from only one locality, viz. Western Australia, 5 km N of Brennan's Ford along Scott River Road NE of Augusta, K. H. Rechinger 5986.1(PERTH, W).

21. Rurnex xmuretii Hausskn. (= R. conglomeratus Murr. x R. pulcher L.), Mitt. Geogr. Ges. (Thr.iringen) Jena 3: 73 (1885). ?ypus; Switzerland, Lausanne, lla ussknec,hi (JE).

Not easilv recognizedbecause both parents have divaricate branching panicles and distant floral whorls which are mostly subtended by a leaf. Valves smaller than R. pulcher with lesspronounced teeth. 6-LSZSZ s8uuds aJrlv :uollEururExa.IoJ HJUgd ol. luas EIJBqJarluEIIBllsnV Sul.t\olloJaql uro4 xatunu Jo suaurrads urnlJBqraq a,\eq o1 Sutiue.r.re flpul{ Jol (H,LEgd) rll.Iad 'urnuBqraH 'ueor0 uellBrlsnv uralsald aql Jo rolprnC AA f rG {uEql 01 qsll.\ I sluaIuatpolAl,ourlty
