A climbing shrub, quite glabrous, except the inflorescences and sometimes the nerve-axils; young branches compressed, at length terete, fuscous when dry. Leaves elliptic to ovate, rarely oblong-elliptic, acutely or subacutely acuminate, shortly acute or rounded at the base, 2–3 in. long, 1–2 in. broad, papery or thinly coriaceous, quite glabrous, rarely with small tufts of rufous hairs in the nerve-axils; secondary nerves 5–7 on each side, oblique, faint; transverse veins subhorizontal, obscure; petiole 4–6 lin. long, slender. Cymes subumbelliform, gathered in lax more or less divaricate axillary and terminal panicles; lower panicles more slender and very loose, up to 3 in. long, the upper often paired, the terminal 3–4-nate, more compound, 1–2 in. long, all finely blackish-furfuraceous; peduncles up to 1 in. long, very slender; bracts minute; pedicels filiform up to 1 lin. long. Calyx campanulate-ovoid, 3/4 lin. long, finely furfuraceous; sepals ovate, subacute, intracalycular glands 5. Corolla finely papillose without, campanulate; tube 1 3/4–2 lin. long, glabrous within above the transverse subsemicircular calli; lobes subulate-linear, from a broader base, about as long as the tube or rather shorter. Anthers not quite 1 lin. long, minutely papillose on the back otherwise glabrous or with 1 or 2 hairs. Disc shallow, sinuous. Ovary-top pubescent; style short, obconical, papillose; stigma campanulate, with a subulate apex.
