Clematicissus angustissima

Clematicissus angustissima is a vine in the Vitaceae family, endemic to the Geraldton area of Western Australia.

The species was first described as Vitis angustissima in 1859 by Ferdinand von Mueller, from a specimen collected by Oldfield on the Murchison River. In 1887 Jules Planchon reassigned it to his newly described genus, Clematicissus,  with Clematicussus angustissima being the type species.
