Atalaya brevialata (Sapindaceae), a new species from the Northern Territory, Australia
COWIE, I.D. AND STUCKEY, B.

A new, rare species, Atalaya brevialata Cowie & G.M. Wightman is described and illustrated. The species is unusual in the genus in having a greatly reduced wing on the samara and the suffruticose growth habit, the latter perhaps an adaption to the region’s wet-dry tropical climate and prevailing near-annual fire regime. It appears to have a restricted distribution to the south of Darwin and its conservation status is evaluated. A key to species of Atalaya Blume in the Northern Territory and Western Australia is provided.
