Twigs terete, densely pubescent, the hairs erect, the indument wearing off with age; terminal buds densely pubescent. Leaves alternate, chartaceous, 6-13 × 2.5-7 cm, elliptic to broadly elliptic, base obtuse or acute, tip acute or acuminate, lateral veins 5-6 on each side, midrib and lateral veins impressed above, tertiary venation immersed, midrib, lateral veins and tertiary venation raised on lower surface; upper surface with scattered, erect hairs, the indument denser on midrib and lateral veins, lower surface pubescent, the hairs erect; domatia lacking. Petioles 0.4-1.2 cm long, with similar indument as twigs. Inflorescences axillary, pubescent, <i>c.</i> 5 cm long, rather few-flowered, bracts sometimes present at anthesis.Tepals pubescent on both surfaces, but less so on inner surface, 1.5-2 mm long. Stamens 9, 4-celled, 1.5 mm long, filaments pubescent, anther glabrous, staminodia 3, pubescent, stipitiform. Ovary and inside of receptacle glabrous. Cupule deeply cup-shaped, 1.4 cm wide, 1 cm high, fruit ellipsoid, 1.6 × 1.2 cm.

Vegetatively, the impressed midrib and lateral vein on the upper leaf surface and the pilose lower leaf surface are characteristic.
