Stem

Tree to 20 m (-25m) tall, stem sometimes buttressed. Twigs fluted or terete, clothed with straight and tortuous, appressed and erect, pale brown hairs.

Leaves

Leaves alternate, simple. Stipules absent. Petioles 0.4-1.4 cm long. Leaf blade elliptic, ovate, or obovate, sometimes narrowly so, 5-12 cm long, 2.-5 cm wide, base cuneate, truncate or rounded, margins entire, apex acute, acuminate or obtuse. Domatia often present, visible under magnification as more or less hooded pits or tufts of hairs at axil of lateral veins and midrib. Leaf undersurface usually with straight and tortuous, appressed and erect, pale brown hairs. Midrib depressed on upper surface. Oil dots ± visible with a hand lens.

Flowers

Inflorescence paniculate, axillary. Flowers bisexual, 3-merous. Perianth tube 1-1.7 mm long, outer tepals larger (0.7-1 mm long) than inner tepals (0.6-0.9 mm long), scarcely opening, forming a cylinder around anthers and ovary, cream, green or yellowish green. Stamens three; staminal glands six, free from one another. Staminodes three, usually differentiated or undifferentiated into a head and stalk. Ovary superior.
