Shrubs. Young branchlets brown pubescent, soon glabrate. Leaves clustered at branchlet apex, appearing opposite or verticillate, biennial; petiole 5–15 mm, pubescent at first, later glabrate; leaf blade green and shiny adaxially, oblong, lanceolate, or narrowly lanceolate, 5–16 × 1–5 cm, thinly leathery, pubescent abaxially at first, soon glabrate, lateral veins 6–7-paired, slightly convex abaxially, indistinct adaxially, reticulate veins indistinct, base cuneate, margin flat, apex acute to long acuminate. Inflorescences 1 or 2 in leaf axils at branchlet apex, umbellate, 3–9-flowered; peduncle 1–1.5 cm or sometimes absent, brown pubescent; bracts narrowly lanceolate, shorter than sepals; pedicels 2–5 mm, pubescent. Sepals lanceolate, 5–6 mm, shortly pubescent. Petals white or pale yellow, ca. 8 mm. Stamens ca. 6 mm. Ovary pubescent; carpels 2; placentas 2, parietal; ovules 4 per placenta; stipe 5–7 mm, pubescent. Capsule compressed ellipsoid, 1.6–2.5 cm, dehiscing by 2 valves; pericarp thin; placentas at base to middle of valves. Seeds ca. 8 per capsule, darkish red, irregularly oblong or subglobose, 4–6 × 5–7 mm; funicle ca. 1.5 mm. Fl. Mar–May, fr. Jun–Dec.
