Trees 3–5 m tall, rarely to 15 m tall, with loose branches. Branchlets purplish brown or blackish brown, terete, slender, glabrous or subglabrous, sparsely lenticellate; buds purplish brown, narrowly conical, margin of scales pubescent. Stipules caducous, lanceolate, membranous; petiole 1–2.1 cm, sometimes sparsely pubescent; leaf blade ovate or narrowly elliptic, 4–7 × 2.5–3.5 cm, abaxially pubescent along midvein when young, glabrescent, base rounded, rarely subcordate or broadly cuneate, margin entire basally, minutely serrate apically, apex acute. Raceme 4–5 × 3–5 cm, many flowered; peduncle initially sparsely pubescent, glabrescent; bracts caducous, linear-lanceolate. Pedicel 0.8–2.8 cm, slender, initially sparsely pubescent, glabrescent. Flowers 3–4.5 cm in diam. Hypanthium cupular, abaxially initially pubescent, glabrescent. Sepals lanceolate or triangular-lanceolate, ca. 5 mm, nearly as long as hypanthium.
