Two newly described species and a draft key to the species of Sida s.lat. from Western Australia
BARKER, R.M.

There are a number of new native species of Sida listed in the Western Australian Herbarium’s FloraBase that have not yet been formally described. Of the 56 accepted species names presently listed, nearly half represent undescribed taxa. These are cited as either manuscript or phrase names. Two of the species, Sida ectogama W.R.Barker & R.M.Barker and Sida arsiniata R.M.Barker, previously known by phrase names, are here described and a draft key is provided for the native species of Sida found in Western Australia.
