About
Cynanchum ellipticum is a South African climbing plant of the family Apocynaceae. It has slender stems and branches, exuding milky, bitter latex that is non-irritant. It occurs in coastal scrub from Cape Town as far north as Mozambique and further inland up to 1300 m, and may be found on flats or moderate slopes, in sand or between rocks, in indigenous forests and along forest margins and thickets, frequently occurring in disturbed habitats.
This sprawling twiner has opposite semi-succulent leaves 20–40 mm long, 10–20 mm wide, elliptic to oblong, broadly elliptic with a prominent tip (apiculate) and a ring-like thickening where the petioles join the stem. Helicoid cymes of tiny, white or cream flowers grow from the axils of the leaves, having a tubular corolla and being sweetly scented. The horn-shaped fruits or follicles contain club-shaped plumed seeds.
