Climbing or scrambling, perennial, succulent geophyte. Stems succulent and leafless, 30-1000 mm long; produced from a cluster of slender fleshy roots. Leaves vestigial, up to 5 mm long. Flowers 1 or 2, produced laterally at nodes; pedicels ± 10 mm long. Corolla cylindrically complicate, up to 60 mm long; tube mainly green, ± 37 mm long, basal inflation ovoid-ellipsoid, 12-13 x 10 mm, narrowing abruptly and turning ± 90° into an upright trumpet-shaped tube, mouth ± 15 mm diam.; lobes narrow, ± 4 mm long, expanded and connivent into parachute-like canopy, 16-18 mm diam. covering tube mouth, margins 10-crenulate, fringe long, pendulous, clavate and vibratile. Corona: interstaminal corona lobes scale-like and connate at base, forming a bowl surrounding gynostegium, apex extended into 2 filiform tortuous appendages ± 3 mm long; staminal corona lobes fused basally to interstaminal corona, filiform, connivent over style-stigmahead, 3.0-3.5 mm long.
Succulent climber to 1 m with smooth stems; sap clear. Leaves to 5 mm, caducous. Flowers 30-60 mm long, tube flaring above, whitish heavily veined with green and purple, petals with broad expanded apices fused together into an umbrella-like canopy, ciliate.
Like C. namaquensis but corolla tube whitish, heavily veined with green, with short and broad lobes forming a broad cage over the tube and remaining fused at tips.
