Stems 3 ft. or more long, scrambling, fleshy, terete, with lax hanging branches, marked with the scars of fallen leaves, glabrous, glaucous (Thonning). Branches alternate or sometimes somewhat clustered, 1–3 lin. thick, leafy when young. Leaves alternate, 1–3 lin. apart, with a whorl at the base of the umbels, sessile, 1–1 1/2 in. long, 1–2 1/2 lin. broad, linear-lanceolate or linear, acute, tapering to the base, entire, glabrous, with the midrib prominent beneath, veins invisible. Umbels terminal, with about 4 simple rays 3–10 lin. long, each with 1 involucre and a pair of orbicular-obovate thin bracts about 2 lin. long and broad, glabrous. Involucre shortly pedunculate within the bracts, about 2 lin. in diam., cup-shaped, glabrous, with 5 glands and 5 rounded subentire lobes slightly woolly on their inner surface; glands 2/3– 3/4 lin. in their greater diam., suborbicular, or transversely elliptic, yellow (Thonning). Ovary globose-trigonous, glabrous, exserted on a pedicel about 2 lin. long and curved to one side; styles about 1 lin. long, shortly united at the base, then widely spreading, emarginate or minutely 2-lobed at the apex.
