Green (1983) removed somespecies from Thryptomeneto his new genusMalleostemon, brtrTot thosenow corsideredto belong in Alrt4. While Green( 1980, 1986)made useof someof the unusual featutesofT. maisonneuveitodistinguj.sh it from the other speciesincluded in his keys to the arid zone and South Australian speciesof ,he otherwise drew little attention to the atypical characteristicsof this species.

Methods

Apartfromtype materialborowed from MEL, all specimenscited arehoused at PERTH, although duplicatesmay exist in other herbaria. All measurementswere takenfrom dry pressedmaterial. Leaf measurementswere obtainedfrom the largestleaves on eachspecimen. Filament lengthswere taken from the longeststamens ofeach flower and style lengthsfrom yery matureflowers and young fruits.

Distdbution maps were preparedusing distribution data ftom PERTH herbarium specimensand additionaldata from Green ( 1983). Th€ Botanical Provincesused are those defined by Beard (1980). Conservationcodeshave been assigned according to theWestern AustmlianD€partmentof Conservation and Land Management'ssystem, the categoriesof which are defined at the end of this Naytsia issue.

Relationships and differ€ntiation of Arrrra

Ahla is one of over 20 generacuffently recognizedin the Ci amelaucium alliancein the informal classificationofthe Myrtaceaedevised by Briggs & Johnson(1979). Phylogeny wirhin the alliance is still far from certain, but there appearsto be a good basisfor separationof this group from other alliancesin the family, asdiscussed by Johnson& Briggs(1985).

Some problems in the delimitation of genera within the alliance have been satisfactodlydealt with in recentyears, notably for andits closerelatives (Craven 1987a,b). Among the generaBentham (1867) included in his very broadly circumscribed conceptof L., someprogress has been made by the descriptionof OchrospermaTrudgen(Trudgen 198?)and the reinstatementof Lindl. (Bean 1997), Eurlomyrtus Schauer(Trudgen in press),Rlnzic Schauer(Trudgen 1986) and Triplarina Raf. (Bean 1995). However there are significant problems remainingin the delimitationofgenerain thealliance, particularly in the group includingThryptomene. Theseproblems and the lack ofcomparative studiesofthe morphology and anatomy ofother genera within the ChameLauciumalliance limit the certainty with which relationships of car. be discussed.

In anther morphology, Aluta appeaxsto show a closer relationship to Malleostemon tharr to Thryptomene ajndrtsallies. Aluta a\d Malleo stemonbothhaye anthers (seeFigure I ) with the following characteristics:

1. The groovesof eachcell are oblique, not parall€l to the connective,and meet towards the apex of the anther. This indicatesthat the orientation of the two cells is divergent rather than parallel.

2. The adjacentparts of the two cells (i.e. thoseparts locatedto the inside of the two grooves)differ in shapefrom the outer parts,becorning expanded towards the lower end such that they meet and are fused along the length of the anther connectiye.

Both the bracteolesand sepalsin Aluta arc parlially membranous,with the remaindersomewhat to veryherbaceousandusually prominently dottedwith oil glands. At filst the membranousportion(s) are clear-translucentbut they may becomewhitish and thicker with age. The herbaceousportion of the bracteolesis very thick, keeled and greenor partially green. In the sepalsthe herbaceousportion is usually much less thickenedand may becomemore membranousas the sepalsage.

In young fruits the disc is deeppink to dark red. By the time the fruit hasfully matured,the and usually also the petals have been shed,but the sepalsremain attached. At this stageboth the bracteolesand the sepalsare quite glossy. The bracteolesare persistentfor a while after the fruits are shgd. The two bracteolesof eachpair usually overlap at the basewhere the membranousmargins are broadest. Retentionof the paperysepals in most taxa may resultin the fruits being more easily wind- blown, promoting wider dispersalof the seeds.

Genetic and breeding systems. Like most other genera of ,Aluta Vobably has a base chromosomenumber of I l. More chromosomenumber counts are needed,however, as there is only one record to date for the ,a tetraploid number of c. 22 for Aluta maisonneuvei. The evidently favour outbreeding,having protandrousflowers that appearto be suited to pollination by small insects,

Aluta maisonneuyei (F. Muell.) Rye & Trludgeq comb.nov.

Thryptomenemaisonneuyei F. Muell. (Mueller 1864:6445). Zyper Finke River, central Australia lNorthem Territoryl, J.M. Stuart (holo: MEL70712).

Sftrabs 0.3-1.5(1.8) m high, often widely spreading,up to 2.5 m wide, glabrous; leaf-bearing branchletsmostly arising at anglesof 30-60 degrees,somewhat indented on the 4 angles;leaves fairly crowded on the branchlets, almost appressedto patent but usually widely antorsei older stems developingflaky deepred-brown bark with loosestrips readily shed.Petioles less than 0.2 mrn long. fuaf blades narowly obovate to depressedelliptic in outline, l-2.5 x 0.7-1.6 mm, 4-angled and prominently 4-ridged, with a flat abaxial surfacebroader than the oblique or perpendicularlateral surfaces,the abaxial surface often somewhat concave,the ridges smooth to coarsely denticulate, scarcelypointed at apex;glands usually 2 6 prominentones in I or 2 rows (sometimesmore when in 2 rows) on eachlateral surface, usually few or no prominentglands elsewhere, up to 0.1 mm diameter. Inflorescencewith 1-3(5) pairsofflowers in an almostterminal cluster or rarely in more thanone cluster per branchlet;peduncles up to 0.8 mm long but often very red:uced.Bracteoles very broadly ovate, 1-1.8 mm long, acuteand with a minute to prominentapical point; membranousmargins 0.2-0.4 mm wide, minutely denticulateor entire. Flowers 454mmdiameter; disc pink or red. Sepalsbroadly to depressedovate, 0.5-1.3 mm long not including auricles;vegetative portion reaching or almost reachingapex, ovate or narowly ovate,keeled and incurved at apex,often reddish; auriclesusually prominent, extending laterally and usually also somewhatto far below the base of the , up to 0.6 mm below baseof sepal,denticulate. Pelals almost circular, 1.1-2.5 mm long, white or pink, denticulate. Stamens5(6), opposite the sepals,sometimes. alternating with staminodes;filament 0.5-l mm long, pink to red; antherc. 0.3 mm wide; gland often reddish. S/cmrnodesusually lessthan 0.1 mm long but prominent and up to c. 0.8 mm long in somespecimens. Ovules 4. Style 0.5-l mm long. Frail depressedglobular to broadly ellipsoid with an almost truncateto strongly convex apex, 1.5-2 mmlong, very rarelyfertile, when fertile 1-seeded;disc1.8-2.3 mmdiameter. Seedalignedacross the fruit, probably somewhatreniform and c. 1.1 mm long.

Distribution. Distributed from Meekatharrain the EremeanBotanical Provinceof WesternAustralia eastto SimpsonDesert in Northern Teritory and south-eastto nearLake Acraman in SouthAustralia (Green1980: Map 1). Seealso Figure 4.

'fhrottgh Habitat. most of its rangeAfula maisonneuveioccrrs commonly with spinifex on red sand dunes (both on and between the ridges) and sandplains,and is often the dominent speciesin open shrublands,although sometimesthe dominant speciesare mallees or other Eucalyptus speciesor occasionally other genera srch as Cqsuarina and Acacia, However from Meekathara east to Wongawol Station,most specimensare from high rocky sites,e.g. the tops ofbreakaways,and the soil is sometimesyellow and/or clayey.

Chromosomenumber. 2t= c.22 (Rye 1979). The singlechromosome number record is from subsp. auriculata. The voucher specimen(8.L. Powell73097) was collectedfrom Loma Glen Station,with no habitatrecorded. Judging by its locationand the shapeof its leaves,however, this specimenappears 'breakaways' to be a representiveof the variant of the speciesthat occurs on ar atypical high rocky habitat.

Conser't)ationstqtus. Both subspecieshave abundantpopulations over a wide distribution.

Note.r.Subsp. ruai,r onneuveiis distirLguished from subspau riculataby ttsleaYes with veryobliquely angledlateral surfaces, each usually with tworows ofprominentoil glands. Subsp. aarlcllala usually hasnarrowerleaves, with thelateral surfaces narrowet and modelately oblique to almostperpendicular andwith theprominent oil glandsmainly located in a singlerow.

Thesecond most important difference between the two subspecies isthatthe fruit usuallyhas much moreprominent gaps or pittingon thefloraltube ornamentation in subsp.malsotlneavei than in subsp. auriculata,the latterhaving a moreuniformly wrinkled appearance to thefloral tube. Sepalshape variesgreatly in bothsubspecies but thereappears to be sometendency for subsp.quriculqta to have moreobtuse sepals than the typicalsubspecies.

Withinsubsp. maisonneuvei there is considerable variation in thesize ofthe pits on the hyPanthium, acharacter which correlates fairly well withthe width and degree ofobliqueness ofthe lateralsurfaces of the leaf. Plantsfrom the north-westernpalt of the subspeciesrange, including a majorityof the WesternAustralian specimens, tend to haveboth the lalgest pits andthe broadest and most oblique (closestto horizontal)lateral teaf surfaces. Many of theNorthern Territory specimens, including the type,also have relatively large pitting on the hypanthiumand broad lateral surfaces on the leaf. A secondvariant with lessobvious pitting on thehypanthium, and sometimes also narower lateralleaf surfaces,occurs in centralAustralia, overlapping with therange of thetypical variant. Figure 4 shows the knowndistributions of the typicaland atypical variants of the subspecies,the formerwith pits usuallynearly as large and obvious as those on thedisc, the latter with pitsmuch finer thanthose of thedisc or scarcelyevident.
