Flora 49traverse the Pinjarra Plain. In the past it is probable that transport of plant propagules of species likeTrymalium odoratissimum from the Darling Range via waterways such as Yule Brook was an important wayin which the large species pool of the Pinjarra Plain was developed. Most of its previous habitat on the SCPhas been cleared and degraded.Family SapindaceaeDodonaea ceratocarpa. This shrub is generally confined to granitic habitats in the Darling Range, on theLeeuwin-Naturaliste Block and along the south coast from Cape Leeuwin to Cape Arid. It also inhabitscoastal limestone over granite and uncommon basalt habitats in the lower south west and south coastal areas(Western Australian Herbarium, 2009). The MKSEA and BFS 387 (Keighery and Keighery, 2000) appear tobe the only locations on the Swan Coastal Plain where this species has been recorded. The form of Dodonaeaceratocarpa that occurs in BFS 387 and the MKSEA requires further taxonomic study to determine if itdiffers from other populations beyond the Swan Coastal Plain.Family ThymeliaceaePimelea imbricata var. major. This is a taxon restricted to Pinjarra Plain clay flats and pans. The mostsouthern population known is on the Busselton Plain in the Fish Road Bushland (B.J. Keighery, DEC. pers.comm.) The most northern population is just north of Gingin. This subspecies is endemic to the SwanCoastal Plain.Tauss, C. and Weston, A.S. (2010).
