Sida picklesiana (Malvaceae), a new species from the Murchison-Gascoyne region of Western Australia
MARKEY, A.S., DILLON, S.J., COCKERTON, G.T.B. AND BARKER, R.M.

This article provides a description of the recently discovered species Sida picklesiana A.S. Markey, S.J. Dillon & R.M. Barker. This species is known from an area near Wiluna in Western Australia’s Murchison-Gascoyne region, where it occurs in a variety of habitats. Sida picklesiana has conservation priority status as it has a relatively limited distribution. Major differences between Sida picklesiana and the species with which it is most likely to be confused are discussed, and the most recently published draft key to Sida is amended to include this new species.
