Twining/climbing, subsucculent geophyte. Stems often much branched and tangled in basal vegetation, up to 5 m long; from fibrous or fleshy rootstock. Leaves ± fleshy, oblong to ovate-lanceolate, up to 75 x 50 mm, base cuspidate; petioles 10-15 mm long. Inflorescence: peduncle up to 35 mm long. Flowers 1 or 2 at nodes; pedicels 8-16 mm long. Corolla complicated, up to 50 mm long, basal inflation small and globose, curved shortly after through 90°, then expanding trumpet or funnel-like into 15-20 mm mouth, throat hairy; lobes free at base, broadly deltoid, margins replicate, connivent over tube mouth and producing a short stalk, 5-15 mm long, becoming inflated at apex forming an elliptic or subglobose knob, 3-5 x 2-5 mm and which is fluted and cage-like, margins replicate and ciliate (-like an umbrella with an antenna). Corona: interstaminal corona lobes dorso-ventrally flattened, scale-like, connate basally, upper margin cleft and bidentate; staminal corona lobes fused basally to interstaminal corona, narrowly ligulate, broader at connivent apices and flexed outward.
