Shrubs or small trees, 3-6 m tall. Branchlets robust, olive green or chestnut brown; bark densely glandular. Petiole stout, 1.2-2 cm, sulcate adaxially, glabrous; leaf blade abaxially pale green, adaxially distinctly green, oblong-elliptic, 8-16 × 4-7 cm, thickly leathery, both surfaces glabrous, abaxially sparsely glandular, midvein slightly impressed adaxially, broad, secondary veins in 6 or 7 pairs, arcuate ascending, reticulate veins prominent on both surfaces, base rounded-obtuse, margin irregularly spinose serrate except near base, apex acute or shortly acuminate. Racemes axillary, solitary, erect, shorter than leaves, 7-13 cm; rachis, bracts, pedicels, and calyces sparsely puberulous and sessile or substipitate reddish glandular; bracts leaflike, sometimes conspicuously elongate, to 1 cm. Flowers numerous; pedicel spreading to pendulous, 2-3 mm. Calyx shallowly cupular; lobes linear-lanceolate, shorter than or subequaling petals, 3-3.5 mm. Petals erect at anthesis, slightly curved apically, white, lanceolate, 3-4 mm, margin puberulous, sometimes sparsely glandular. Stamens conspicuously longer than petals and ovary, ca. 5 mm; filaments puberulous; anthers ovoid. Ovary superior, glabrous. Capsule ca. 7 mm. Fl. and fr. Jun-Nov.
