MASLIN, B.R. AND VAN LEEUWEN, S.
Preparatory to publishing books on the Acacia Mill. flora of the Pilbara region, 10 new species (A. bromilowiana Maslin, A. fecunda Maslin, A. leeuweniana Maslin, A. minutissima Maslin, A. subcontorta Maslin, A. subtiliformis Maslin, A. trudgeniana Maslin, A. robeorum Maslin, A. thoma Maslin and A. walkeri Maslin) and two new subspecies (A. catenulata C.T.White subsp. occidentalis Maslin and A. steedmanii Maiden & Blakely subsp. borealis Maslin) are described. Acacia coriacea DC. is now more narrowly circumscribed to include subsp. coriacea and subsp. pendens R.S.Cowan & Maslin only, while the former A. coriacea subsp. sericophylla (F.Muell.) R.S.Cowan & Maslin has been reinstated as a distinct species (A. sericophylla F. Muell.). Notes on the variation in Western Australian plants of A. drepanocarpa F.Muell. are provided. Acacia bromilowiana, A. fecunda and A. subtiliformis are Priority Three taxa and A. leeuweniana is a Priority One taxon according to the Department of Environment and Conservation’s Conservation Codes for the Western Australian Flora.
