Abstract

Davis, R.W. & Tauss, C. A new and rare species of Ptilotus (Amaranthaceae) from a suburban wetland of the eastern Swan Coastal Plain, Western Australia. Nuytsia 21(3): 97-102. Ptilotus christineae R.W.Davis & Tauss, currently known from only one small population in the Greater Brixton Street Wetlands, about 14 km from the centre of the city of Perth, is described and illustrated. A key to Ptilotus R.Br. of the Swan Coastal Plain Biogeographical Region is provided.Ptilotus christineae is clearly distinguished from all congeners in the SCP by the combination of its slender rhizome, spathulate leaves, erect flowering shoot, five fertile stamens and wetland habitat.
