Species

Characteristics

Much-branched shrub or small tree 1.8–4.5 m. tall; young branchlets pubescent; bark grey, smooth, soon peeling to reveal a slightly rough glabrous surface yielding resinous secretion; wood hard; hairs on young leaves, calyces, etc. also with resinous secretion.. Leaves usually ternate, mostly crowded on lateral shoots, deciduous, obovate, 1.5–10(–14) cm. long, 1–6.5(–9) cm. wide, abruptly acuminate at the apex, strongly narrowed to the base, the actual base cuneate, rounded or minutely cordate, sparsely to densely often rather scabrid-pubescent above, sparsely to densely pubescent or velvety beneath but even then with venation visible as a reticulation with reduced indumentum, often rugose above; petioles 0–1.5 mm. long; stipules forming an ovoid hairy tip 2–8 mm. long to shoots but soon splitting into ovoid parts.. Flowers 5–6-merous, solitary or 1–3 in the upper axils of leafy shoots; pedicels 1–4 mm. long, pubescent.. Calyx-tube ovoid, 2 mm. long, very densely spreading pubescent with pale hairs; limb-tube 1.5–2.5 mm. long, 5-winged by the decurrent lobes, pubescent; lobes leafy, oblong, 0.3–2.2 cm. long, 1–3.5 mm. wide, held radially to the tube, pubescent.. Corolla white, sometimes becoming yellowish, strongly scented; tube narrow, 1.2–5 cm. long, 3.5–10 mm. wide, sparsely to densely pubescent outside; lobes oblong-obovate or spathulate, 0.7–4.5 cm. long, 0.4–1.2 cm. wide, sparsely pubescent outside.. Fruit globose or ellipsoid, 0.9–1.4 cm. long, 0.9–1.4 cm. in diameter, obscurely ribbed, densely spreading pubescent, crowned with the persistent calyx.. Seed-ball with seeds separated by pale matrix; seeds reddish brown, 3.5–4 mm. long, 3 mm. wide, reticulate.

A shrub or small tree. It grows 2-5 m high. It has many branches. The wood is hard. Young branches have hairs. The leaves are mostly crowded on side shoots. The leaves are 2-10 cm long by 1-7 cm wide. They are oval and taper to the tip. The leaves are hairy underneath. The flowers occur as one to three in the axils of the upper leaves. The fruit is 9-14 mm long by 9-14 mm wide. The seeds are reddish-brown.
