M.G. Gilbert (2006) Leptadenia. Flora of Somalia 3: 166-168
Plants leafless shrubs or woody twiners with well-developed leaves; latex clear and watery. Inflorescences subsessile or pedunculatem in many flowered extra-axillary umbels. Corollas rotate, tubes short and campanulate, lobes fleshy, pubescent or lanate with slightly revolute margins. Coralline corona lobes present between the corolla lobes; gynostegia largely enclosed by the corolla tubes and corolline corona lobes, with or without an annular corona at their bases; anthers incumbent over the stigmatic head, lacking apical appendages; pollinaria subhorizontal or suberect, corpuscula minute, translator arms flattened and obtriangular; pollina somewhat flattened, each and with a translucent germination zone. Follicles developed singley, fusifirm, with a long-attenuate beak; seeds flattened, smooth, with a tuft of silky hairs at one end.
Leptadenia includes 6 species (POWO 2022). They are native across northern Africa, Madagascat, the Arabian Peninsula and south to southeastern Asia.
Note: GBIF records include introduced and cultivated plants. Consequently, the distribution shown often differs from statements about a taxon's native distribution.
