Abstract
Twenty-five species of Pultenaea endemic to Western Australia are revised at and below species level. Three species (P. daena Orthia & Chappill, P. indira Orthia & Crisp, P. wudjariensis Orthia), three subspecies (P. calycina subsp. proxena Orthia & Chappill, P. indira subsp. monstrosita Orthia, P. indira subsp. pudoides Orthia) and two informal taxa [P. ericifolia ‘southern’ (Orthia 39), P. sp. Mt Lesueur (Beard 7827)] are described for the first time. The status of all varieties of P. verruculosa is changed: P. verruculosa var. brachyphylla (Turcz.) Benth. is reinstated at species level, P. verruculosa Turcz. var. verruculosa and P. verruculosa var. pilosa Benth. are placed in synonymy of Pultenaea verruculosa Turcz., and P. verruculosa var. recurva Benth. is found to be a nomen dubium. Three names in common usage are found to be illegitimate: P. conferta Benth. [now P. purpurea (Turcz.) Crisp & Orthia], P. obcordata (R.Br.) Benth. (now P. quaerita Orthia) and P. drummondii Meisn. (older name P. brachytropis Benth. reinstated). The Pultenaea species occurring in both western and eastern Australia are discussed and addenda made to the treatments previously published by de Kok and West (2003, 2004). The status of P. vestita R.Br. and P. juniperina Labill. as naturally occurring WA species is questioned.
