Hypselodelphys

(K.Schum.) Milne-Redh.
Description:
Subscandent, much branched perennials with bamboo-like shoots simple below and clothed with sheathing coriaceous cataphylls, branched and leafy above. Leaves: petiole jointed shortly above top of sheath; blades asymmetric. Inflorescence terminal, simple or sometimes branched at base, spike-like with a jointed rachis and a 2-flowered cymule at each distichous node, each flower subtended by a small fleshy bracteole. Corolla: tube
Distribution:
Species 5, trop. Africa; sthn trop. Afr. 4, Angola. Andersson (1998) notes that the only important difference between this genus and Trachyphrynium braunianum (K.Schum.) Baker, the only species of this genus, is in fruit structure, and that this distinction is not very convincing.
