Trees, to 16 m tall, to 1 m d.b.h. Bark grayish white, smooth. Young twigs, buds, petioles, leaf blade abaxial surfaces, leaf blade adaxial surfaces when young, and brachyblasts densely appressed grayish white to brown villous. Twigs black, ca. 3 mm in diam., remaining with pubescence. Petiole 0.6-1.5 cm, without a stipular scar; leaf blade narrowly elliptic to narrowly obovate-elliptic, 8-15 × 3-5 cm, midvein adaxially impressed, secondary veins 9-15 on each side of midvein, reticulate veins slender, dense, and prominent on both surfaces when dry, base rounded to broadly cuneate, apex acuminate to acute. Brachyblasts stout, ca. 7 mm; bract scar 1, ca. 2 mm below tepals; spathaceous bract 1, just next to tepals. Flower buds ovoid, ca. 1.5 cm. Tepals ca. 12, in 4 whorls; outer tepals 3, narrowly obovate, 1-1.2 cm; tepals of next inward whorl obovate, 1.3-1.5 cm; tepals of innermost 2 whorls narrowly ovate, narrower and smaller, ca. 1 cm. Androecium exceeding gynoecium; stamens 4-5.5 mm; filaments broad and flat, 1-1.5 mm; connective exserted and forming a 1-1.5 mm obtuse tip; anthers 3.5-4 mm, thecae divaricate 0.5-0.8 mm away from each other, dehiscing introrsely and laterally. Gynophore ca. 1 mm, pubescent; gynoecium cylindric, ca. 5 mm; ovaries globose, densely tomentulose. Fruit usually curved because of carpels partly undeveloped, 2-3 cm; mature carpels black, obovoid, 1.5-2 cm, conspicuously white lenticellate, apex rounded. Seeds broad and flat, transversely ellipsoid, ca. 1.5 × 1 cm, adaxially broadly furrowed, base mucronate, apex impressed; endotesta black. Fl. Apr-May, fr. Aug-Sep.
