Podsof,4. venulosaarestraightwhilethoseofVt. lanigem are at least arcuate to once-coiled, insofar as they are known, forwe have not seen the pods ofvar. whanii. While indumentum in the two species is variable there are patterns in density, hair type and orientation, particularly on branchlets and peduncles, which make these useful secondary character for distinguishing the species (see descriptions below). The resin-hairs which are common in A. venulosabutinfrequentinA. lanigemaresimilartothosefoundinA. oswaldiiF.Muell. andmany other species. They appear similar to the C-hairs Rutishauser and Sattler (1986) described in A. longipedunculata Pedley.

Woolly Wattle, Hairy Wattle. Typification. Although Cunningham listed no collections in theprotologue ofA. lanigera, he cited the locality, “rocky barren ranges in the interior” [ofN.S.W.]; theprotologue includedcharacters of bothflowersandfruit. Severalfloweringandfruitingcollections,labelledandunlabelled,areinvolved on a numberofherb. K sheets. From study ofCunningham Specimen Lists in thearchives at K, we have concluded thatCunningham collected flowering material ofA. lanigera in theBathurst region andnorthwardaroundSeptember 1822,towhichhegavethenumber221;onareturntripinDecember ofthe sameyearhe collected fruiting material for which he used the samecollection number. This phenology is borneout by modern collections. Because the lower (flowering) specimen on a herb. Hooker sheet at Kew is annotated (on aslip-on label in Cunningham’s hand) with“Acacia lanigera C” and the locality given in the protologue, we here designate it as the lectotype. This specimen is un-numbered, but itis a very good match foranother Kew specimen which has aCunningham slip- onlabelthatisannotated“221/1822”. ThelectotypeisthereforeassumedtobepartofCunningham’s 221 collection gathered from the Bathurstregion around September 1822. Thefruiting material on thelectotypesheet is unlabelled,butmay wellrepresenttheDecembergatheringoftheCunningham 221 collectionandisthereforetreatedasaprobableparalectotype. Thereareduplicatesofthesetwo specimens on the othersheetsatKew. Theonly otherspecimen ofrelevance isCunningham 19 (in flower) which is labelled as having been collected from near BathurstinJuly 1823; wehavetreated this as aparalectotype.

We have notseenspecimens,eitherat KorPR, annotated by Domin asA. lanigera var. brachyphylla', this name was based on a Macarthur collection from N.S.W. However, there is a Macarthurspecimen at K, annotated by Bentham as “lanigeraCunn. var. brevifolia”. a name which was neverpublished. Asthis specimen accords well withDomin’s very briefprotologue and as his epithet “brachyphylla” is the Greek equivalent ofBentham’s “brevifolia”, it is possible that the MacarthurspecimenisthetypeofDomin’sname,eventhoughtheauthorhasnotannotatedthesheet.

Pedley(1978:207)citedCunningham85 [sphalm“25”inPedley]collectedinMay 1827 from “Barren country lying north ofthe Dumaresq River, in 29°S” as the holotype ofA. venulo.sa. ThiscollectionoriginatedfromCunningham’sherbariumandwasdonatedtoKin 1862;itcomprises alarge and asmallerbranchlet, the latterwith aCunningham field tagannotated “85/1827”. While the two branchlets described above are undoubtedly part ofCunningham’s original collection of A. venulosa therearereasonstoquestion whetherBenthamactually usedthis material in drawing up theprotologue: (1)inthelowerrighthandcornerofthesheetBenthamhaswritten“152A. venulosa” which wasprobably addedafterpublication becausethe“152” isthetaxon numberunderwhich the speciesappearedintheoriginalpublication;(2)thecollectinglocalitydoesnotagree withthatgiven intheprotologue,namely,“Liverpoolplains”. Indeed,theonlyspecimenwehaveseenwiththelocality given in theprotologueand annotated “A. venulosa” in Bentham’s hand, istheoneoriginatingfrom Hooker’s herbarium atKand which wehavelistedaboveastheholotype. The specimen is labelled (inanunknownhand): “Acaciaclavata’783AC.seelist 1829";thislistisinthearchivesatK,entitled “KewCollectors. A.Cunningham. Miscellaneous 1816-38 VI. SpecimensofplantsofNSWsentto Dr. W.J. Hooker 1829”. Inreferringto number83 in the list, onefinds“Acaciaclavata m/s. Allied toA.falciformisandpenninennsDecandolle/ thisspec® ofAcaciaisfrequentinbarrenforest-landin the northofLiverpool Plains/flowering inJuly.” It isunlikely thatCunninghamcould have related 72 NuytsiaVol. 10,No. 1 (1995) the material ofA. venulosa to eitherofthe listed species, forthey are extremely unlikeA. venulosa. Consequently,weconcludethatthislabelisprobablywronglyattachedtothisspecimen,butthisdoes not alter its status as holotype.

Discussion. Bentham (1842: 367) described A. venulosa var. lanata based on Cunningham 91 and 98, collected July 1827; laterhe wrote on the sheet bearing Cunningham 98: “A. ixiophyllaBenth. var./(A. venulosaBlanataBenth. inLond.Jour.)”.
