Trees or shrubs, 2-20 m tall. Branches grayish, pale to yellowish lepidote, sometimes glabrescent. Leaves alternate, to 50 cm; petiole and rachis lepidote or glabrous; petiolules 1-15 mm, sometimes slightly inflated, sparsely to densely lepidote, sometimes glabrescent; leaflets 3-9, alternate to subopposite; leaflet blades elliptic, oblong, ovate-lanceolate, or lanceolate, 5-20(-30) × 2-7.5(-11.5) cm, papery to leathery, both surfaces glabrous or adaxially lepidote only on midvein and abaxially lepidote on veins only or on entire surface, midvein abaxially prominent and adaxially depressed, secondary veins (8-)12-15(-16) on each side of midvein, abaxially prominent or depressed, and adaxially flat, prominent, or depressed, base rounded or ± oblique by being cuneate and conspicuously decurrent on one side and rounded on other, apex acuminate to obtuse. Thyrses axillary, botryose, usually shorter than leaves, 2-15 cm in male plants but shorter and with fewer flowers in female plants, densely lepidote or stellately lepidote, few flowered or sometimes with just 1 flower. Flowers unisexual, 3-5 mm in diam. Pedicel 2-3 mm, as long or slightly longer than flower buds, nodiferous, lepidote. Calyx cup-shaped, 1-2 mm, densely lepidote, 3-5-lobed, lobes rounded or sometimes nearly truncate. Petals 3 or 4, suborbicular, ovate, obovate, or oblong, 2-6 mm, concave, outside sometimes sparsely lepidote near base, otherwise glabrous, free from staminal tube. Staminal tube turbinate to campanulate, 2-5 mm, both surfaces gla-brous or outside sparsely lepidote, apical margin entire or crenate/serrulate; anthers (5 or)6(-12), linear, oblong, or ovoid, ca. 0.5 mm, inserted just above inside middle of tube, included or very slightly exserted, both ends acute. Ovary shortly conical, stellately lepidote, 2- or 3-locular, with 2 ovules per locule; style absent; stigma conical, glabrous, 3-lobed. Infructescences 6-10 cm, lepidote. Fruit dehiscent, ellipsoid, globose, or pyriform with base gradually constricted into a 3-16 mm stipe, 1-3 cm in diam., 3-locular, rugose, lepidote, apex rounded, concave, or acute; pericarp woody, hard when dry; calyx persistent, spreading and ± reflexed, lepidote, margin 3(or 4)-dentate. Seeds 1-3 per fruit, completely surrounded by a fleshy usually red aril. Fl. May-Dec, fr. almost year-round.

Forests in hilly regions, dense or sparse forests in limestone regions, ravine rain forests in mountainous regions, evergreen broad-leaved forests, thickets; near sea level to 1600 m. Guangdong, Guangxi, Guizhou, Hainan, Taiwan (Lan Yu), SE Xizang, Yunnan [Bhutan, India, Indonesia, Laos, Malaysia, Myanmar, Papua New Guinea, Philippines, Thailand, Vietnam; Indian Ocean islands, Pacific islands].

Aglaia lawii is the most widespread and variable species in the genus. Although treated here as a single species, in China it could be treated as two subspecies, Aglaia lawii subsp. lawii and A. lawii subsp. oligocarpa. Aglaia lawii subsp. lawii is lepidote on the abaxial surface of the leaflets and has a pear-shaped fruit. It occurs in Guangdong, Guangxi, Guizhou, Hainan, Taiwan (Lan Yu), and SE Xizang (as well as Bhutan, India, Indonesia, Laos, Myanmar, Papua New Guinea, Philippines, Thailand, Vietnam, and Indian Ocean and Pacific islands). Aglaia lawii subsp. oligocarpa has subglobose fruit without a stipe and leaflets almost completely without hairs or scales. It occurs in Yunnan (as well as Indonesia, Laos, Malaysia, Thailand, and Vietnam).
