Depending on which authority is followed, the number of acceptedBonksia speciespdor to the circumscdption of Banksictrosserae ranged between76 (George 1999) and 80 (Thiele & Ladiges 1996). Recognitionof B. cunninghamiiSieber ex Reichb.at specificrank is maintainedat NSW though not by either Georgeor Thiele & Ladiges (Harden2002). Banksia rosseraeis heretreated provisionally as a memberof subgenusBanftsla, sectlon Banksia, series Cyrros4,lls(Benth.) A.S. George. The inclusion of B. rosseraemeans that there are now 14 speciesin this series.Series Cynosrylis was erected as a seriesand more closelydefined by A.S. George in 1981. It differs from Bentham'sconcept ofit as a sectionwhere, through a processof delimitation "as by elimination,it acts a repositoryfor a disparatecollection of otherwiseunplaced species" (Thiele & Ladiges 1996 662). Only thee speciesplaced in the sectionby Benthamwere retainedby George, theothers being refened to threeother series. Impofiant charactersdefining series Cyrtostylis given by George (George 1981 &1999) are cotyledonsobovate to rounded-cuneate,often crenulate,sometimes emarginate; shrub or ffee habit, lignotuberousor not; learesalternate, seffate or ffiangularlobed with flat or slightly recurvedmargins; conflorescencetetminal or on short lateralbranchlets, cylindrical, ovoid or spherical,erect or in one (now two) speciespendulous, the buds typically losing regular pattem before anthesj.siperianth glabrous to villous, quite straight or sometimeswith the limb somewhatupturned before anthesis, relaxedafter anthesis, yellow, ferruginous,orange or reddish;tepals not awned;pistil straightor gently curved;pollen-presenter usually less than 3 mm long,slightly thickened,finely costateor smoothipollen crescent-shaped:/ollicleselliptic mostly lessthan 2 cm long, laterallybeaked after opening,split from stylar point; s€ednlng notched. Many of these defining character states are also common to other series, especially series TetragonaeA.S. George, urd B. rosseraealso sharesmany diagnosticfeatures including glabrous pgrianthsand pendentconflorescences common to speciesin this series. It also keys out to this series in his key to infragenerictaxa (George 1999: 177). 'rather George( 1981:345 & 1999:214) has refered to his seriesC)//osryli.r as being heterogeneous'. After undertaldnga phylogeneticanalysis of Banksla basedon 104 morphological and anatomical cha-ractersusing cladistic parsimony methods, Thiele & Ladigesfound no apparentsynapomorphies for 'widely seriesCl,ros4rlls and haverefered to it as polyphyletic' (Thiele & Ladiges 1996:715). They haveproposed a classificationin which not all taxaare placed in a higherlevel taxon. The basisfor this is that it more accuratelyreilects current knowledge and that taxa placed uncertainly now aremost likely to be movedanyway within the cladogramafter new dataare analysed. These taxa are leflincefiqe sedis, 'clearly The non-monophyletic'series Cylosrylir rsn.rr A.S. Georgehas been virtually dismantled by Thiele & Ladiges,splitting it into three narrowly defined seriesand leaving four speciesincertae sedis, Banl<siaeleg4nJ, a possiblesister taxon to subgenusLrosrylis, has been removed from subgenus Banksia altogetheL thus rendering both taxa monophyletic. Bqnksia elderiana has also been removed from series Cyrtostylisand placed with other speciesthat have pendentconflorescences and straight styles in a redefined series Tetrqgonqe. The original concept of series C)rtorrylls has been redefined to a monophyletic grouping of only four species.
