Shrubs or trees, to 2.5 m tall, the branchlets 4-angled, minutely puberulent, often red when dry, the nodes well spaced, the subnodal area often constricted on drying. Leaves elliptic or obovate elliptic, 7.5-21.0 cm long, 1.5-11.5 cm wide, deltoid or obtuse at the apex, acute or attenuate acute at the base, the costa prominulous above, prominulous beneath, puberulent, the lateral veins 13-20, arcuate, scarcely prominulous but conspicuous beneath, chartaceous, often stiffly so, glabrous above, glabrous beneath except on the veins; petioles slender, 1.0- 5.5 cm long; stipules often deciduous, free or shortly connate, to 1 cm long, often cylindrical, each part slightly retuse at the apex, the lobes of each part conspic- uously rounded, often spreading with age, scarious marginate, subcoriaceous, glabrous. Inflorescences terminal, pyramidal paniculate, to 14 cm long, 5-10 cm wide; peduncle to 7 cm long, relatively stiff, to 0.3 cm wide, puberulent, often drying dark red, the lowermost primary branches opposite, to 5 cm long, the superior primary branches usually well spaced, opposite or alternate and bearing several well-spread pairs of opposite or occasionally alternate secondary branches or sometimes 3 secondary branches terminating a primary branch, the cymules or occasionally individual flowers sessile and disposed along the branches to give a zig-zag effect; bracts and bracteoles persistent, linear or narrowly obovate oblong, the bracts of the lowermost primary branches 0.4-1.0 cm long, paralleling the branches or somewhat reflexed, ciliate. Flowers sessile, the calyx and hy- panthium 2 mm long, the calycine lobes oblong or triangular, 0.2-1.0 mm long, obtuse or acute, spreading, puberulent; corolla yellow or greenish white, the tube cylindrical or subcampanulate, to 6 mm long, scattered puberulent or minutely puberulent all over outside, puberulent within, petaloid, the lobes oblong, ca. 1/4 the length of the tube; anthers oblong, ca. 3 mm long, the filaments ca. 1 mm long, affixed below the middle of the tube; ovarian disc compressed rotund, to 0.2 mm long, wider than long, the style short, the stigmatic lobes ca. 2 mm long.
