Branches terete; young internodes flattened, widening towards top, densely white stellate hairy, later glabrous. Leaves opposite or subopposite, broadly elliptic-ovate, rounded
or acute at base, acute or obtuse at apex, usually crisped margined, (6 -) 12 - 16 x (3 -) 6 - 8 cm,
subcoriaceous, white or rusty stellate hairy on both surfaces when young, glabrous when old;
lateral nerves 5 - 9 pairs; petioles (1 -) 1.5 - 2.5 cm long. Inflorescences centrifugal pseudoracemes;
peduncle more than one in each axil, each 6 - 10-flowered, 2 - 3 cm long; flower buds spathulate,
2 - 2.5 cm long, densely stellate hairy; flowers 2.7 - 3 cm long; pedicels 1.5 - 2 mm long; bract
scaly, 1.5 -2 x 0.5 - 0.6 mm. Calyculus obsolete. Petals united; tube ventricose beneath the neck,
with median split up to half the length, 12 - 16 mm long; lobes linear, unilaterally reflexed, 5 - 7 mm
long. Stamens erect; filaments 5 - 6 mm long; anthers linear-oblong, 4 - 4.2 mm long. Ovary
obconical, 2 - 2.2 mm long; style filiform, 2 - 3 cm long; stigma small, subcapitate. Fruits
