Abstract

A new species of Tylophora, T. corollae Bullock ex Meve & Liede (Asclepiadaceae), is described from Ethiopia. This delicate twiner is characterized by yellow, shield-shaped corona lobes with apical appendages.

The non-twining shrub up to lm high, T. fleckii (Schltr.) N.E. Br., so far known to be endemic to Namibia, is for the first time recorded from NE Africa. The interesting biogeographical implications resulting from the extraordinary gap of 4500km in its distribution are discussed.
