Brachystelma vahrmeijeri grows several pinkish brown stems from a flat, discoid caudex, the top of which may sometimes be seen above-ground. The leaf is broadly elliptic to oblanceolate with a tapering tip and base. The leaves are opposite with entire margins. They attenuate into the stems, making the existence of petioles a matter of opinion.
The pale yellow star-shaped flowers are widely opened, the corolla lobes often curving either backwards or forwards. The distribution area of B. vahrmeijeri lies in the north of KwaZulu-Natal in Maputaland (www.bihrmann.com).
