Description: |
Perennial climber with semisucculent, hairless, twining stems. Leaves somewhat fleshy, ovate, up to 42 mm long, hairless on both surfaces; margin serrulate/denticulate; petiole c. 8 mm long, hairless. Inflorescence extra-axillary, few-flowered, flowers opening in succession; ; peduncle up to 30 mm long; pedicel c. 6 mm long, hairless. Sepals subulate to linear-lanceolate, c.4.5 mm long, hairless. Corolla 49–55 mm long, slightly curved; tube 28–34 mm long, basal chamber double, lower ovoid, 8–8.5 mm long and 3.8–5.5 mm wide, then abruptly expanded into a second subglobose inflation 4.2–6.2 mm wide, gradually narrowed at apex, limb cylindrical, 2.4–3.1 mm wide, widening abruptly to 10–13 mm at mouth, exterior pale cream uniformly covered with purple spots, hairless; sinuses rounded, spreading and gaping; lobes triangular-attenuate, c. 21 mm long, apices converging to form a narrowly conical cage, hairless outside but shortly hairy on the margin, inside white for more than half length, tip dark purplish brown, sparsely stiffly hairy. Follicles and seed not recorded. |
Notes: | This species may be more common and widespread than known records suggest due to long term confusion with Ceropegia nilotica. Both species are very similar vegetatively but clearly differ in the flowers of C. arenarioides bearing much longer corolla lobes which extend into a slender, acuminately tapered beak. |
