Mostly a slender twiner; new shoots very slightly ridged, persisting softly hairy; older stems glabrous, red-brown. Younger developmental stage leaves with silky hairy midribs and margins, glabrescent. Adult leaves alternate, very shortly petiolate; lamina mostly narrowly elliptic to almost linear, 30–65 mm long, (3–) 6–13 mm wide, dark green, discolorous, margin thick and slightly down-turned, apex almost cuspidate; petiole (1–2 mm long). Inflorescences nearly sessile, corymbose, 10 or more almost rotate flowers; distinct rachis 6–10 mm long, peduncles less than 10 mm long; bracts and bracteoles all softly hairy, caducous. Sepals 2–3 mm long, yellow-green, noticeably unequal, green or colour matching petals, hairy on both surfaces, margins woolly. Petals 12–20 mm long, clawed, briefly cohering forming a narrow tube longer than the blade, apices reflexing, hairy. Colour changes: initially very pale blue or pale pink at anthesis, deepening with age and sex phase change, with contrasting deeper colouring spreading from the throat; never cream or yellow. Stamens free, filaments tapering to a wider base, anthers ovoid with a prominent mucro. Pistil with a wide, disc-like receptacle and basal nectary; ovary 3–4 mm long, silky hairy (subsp. cymosa) or glabrous (subsp. pseudocymosa); style can be as long as the ovary when fully extended. Fruit bilocular, berry-like with seeds in separate dry cells, slightly obovate, c. 12–15 mm long. Seeds numerous, discoidal, muricate.
