Four new species of Acacia (Fabaceae: Mimosoideae) with fasciculate phyllodes from south-west Western Australia
MASLIN, B.R.

Four new species of Acacia Mill. sect. Acacia are described, namely, A. dilloniorum Maslin, A. keigheryi Maslin, A. kulinensis Maslin and A. parkerae Maslin. Acacia keigheryi, A. parkerae and A. kulinensis occur in the wheatbelt region of the South West Botanical Province; the first two were previously treated as informal variants of A. lullfitziorum Maslin to which they are related, with the latter more distantly related to these species. Acacia dilloniorum occurs in the adjacent Eremaean Botanical Province, in the south-west extremity of the arid zone; it is most closely related to A. kochii W.Fitzg. ex Ewart & Jean White and is not especially close to the other three new species described here. All four new species are classified as Priority taxa under Department of Parks and Wildlife Conservation Codes for Western Australian Flora. Notes are provided (under A. parkerae) on A. scabra Benth., a poorly known entity of uncertain taxonomic status that is known only from its type.
