Shrubs or trees. Branchlets mostly yellowish green, slightly angled to winged, glabrous. Petiole 0.5--1.5 cm; leaf blade oblong to narrowly elliptic, 5--13 X 2--5 cm, leathery, glabrous, base cuneate, margin revolute and entire or sharply dentate, apex long acuminate to acute, midvein adaxially prominent and often sulcate, lateral veins 4--15 pairs. Inflorescences a basally branched spike or raceme, shortened to a fascicle or up to 6 cm, axis mostly puberulent to pubescent; bracts and bractlets persistent, broadly obovate, 1--3 mm, often glabrous. Ovary glabrous, 0.5--2 mm. Calyx 1--3 mm, glabrous; lobes oblong, slightly shorter than 3 mm. Corolla 3--5 mm. Stamens 10--80, 4--6 mm. Disc white villous, puberulent, or woolly-sericeous. Style ± as long as corolla to much shorter, glabrous or hairy towards base. Drupes ovoid to mostly ellipsoid, 0.5--1.8 X 0.4--1.3 cm, apex with persistent calyx lobes. Seeds and embryo usually U-shaped. Fl. Mar-Dec, fr. May-Dec. Mixed forests; 500--2600 m.

In many collections the petioles in Symplocos lucida are decurrent on the twigs, making the latter ridged to slightly winged. The name S. tetragona has been applied to the extreme condition, but after careful study it is apparent that, apart from winged branchlets, S. tetragona is indistinguishable from S. lucida.
