Characteristics

Climbing shrub with stems several m. long and attaining 3 cm. in diameter near the base, at first fairly densely covered with very short pubescence but later glabrous.. Leaf-blades elliptic, 3.5–11 cm. long, 1–5.5 cm. wide, distinctly acuminate at the apex, cuneate at the base, glabrous save sometimes for some pubescence on the lower part of the main nerve beneath, thin; nodules absent; domatia present; petiole 0.2–1.5 cm. long, pubescent; stipules ovate-triangular, 4–6.5 mm. long, bilobed at the apex, the lobes 1–2.5 mm. long, pubescent or glabrous, deciduous; nodes with long hairs within the stipules.. Flowers heterostylous, (4–)5(–6)-merous, in much-branched panicles 2.5–10 cm. long; peduncle 1–4 cm. long, glabrous or pubescent; secondary branches 0.2–1 cm. long, pubescent; pedicels obsolete or ± 1 mm. long, very shortly pubescent; main bracts ± 3 mm. long, lobed at the base, clasping the stem, rest small, ± pubescent.. Calyx-tube conic, ± 1 mm. long, glabrescent; limb cupuliform, 0.75–1 mm. long, glabrous or sparsely covered with very short almost papilla-like hairs; lobes very short, broadly triangular, ± 0.5 mm. long.. Corolla yellowish, greenish or lilac, glabrous to finely densely tomentose outside; tube 3.25–5.5 mm. long; lobes ovate-triangular, 2–2.5 mm. long, 1–1.5 mm. wide.. Stamens purple, with filaments 2–2.5 mm. long in short-styled flowers, 0.5–0.75 mm. long in long-styled flowers.. Style 1.5–3 mm. long in short-styled flowers and 4–5 mm. long in long-styled flowers; stigma-lobes 0.75–1 mm. long.. Drupes red, ellipsoid, 5–7(–10 in living state) mm. long, 7(–8) mm. wide, with 2 pyrenes; pyrenes depressed semi-ellipsoid, 5.5 mm. long, 4.2 mm. wide, 2.5 mm. thick, ventral face plane, dorsal face obscurely ribbed.. Seeds dark blackish-red, of similar shape, 4.5 mm. long, 4 mm. wide, 2 mm. thick, ventral face rugose, dorsal face irregularly 7-ribbed; albumen ruminate on both faces but particularly between the dorsal ribs.
