Petioles and twigs produce a milky exudate. Petiole 8-15 mm long; lamina oblanceolate, obovate or elliptic, 4-10(-20) cm long, 2-5(-8.5) cm wide, apex bluntly acuminate or obtuse, reddish brown felted on both surfaces when young, becoming glabrous above and leaving a persistent closely appressed hyaline indumentum below; secondary veins 7(-11) pairs, tertiary veins mostly oblique, the higher order veins areolate.
Pedicels up to 1 mm long, reddish brown tomentose or felted. Calyx lobes 5, oblong or narrowly ovate, 8.5-10 mm long, on outside densely tomentose or felted, on inside sericeous, margins fimbriate. Corolla 9-11 mm long, lobes broadly ovate, 2.3-2.5 mm long, apical margin glabrous or with a few minute trichomes. Stamens c. 2 mm long, anthers c. 1.5 mm long, filaments 0.3-0.5mm long. Staminodes oblong or narrowly deltoid, 2-2.5 mm long, glabrous. Ovary broadly ovoid, sericeous, c. 1.5 mm long; style narrowly conical, 7.5-8.5 mm long, sericeous, glabrous on distal one-third.
Two cataphylls produced before the first true leaves. First pair of true leaves elliptic to broadly obovate, apex acuminate to apiculate, base cuneate to attenuate, margins entire. Leaf blades about 9-10 x 3.4-3.5 cm. Petioles about 0.5 cm long. Underside densely clothed in pale brown prostrate hairs. At the tenth leaf stage: leaf blade elliptic to obovate, apex acuminate, base attenuate, cuneate or rounded, hairy on the upper surface along the midrib, undersurface brown from dense, prostrate, medifixed (T-shaped) hairs, about 10-12 lateral veins each side of the midrib; petiole, stem and terminal bud densely clothed in pale brown, mainly prostrate hairs. Seed germination time 36 to 58 days.
