形態特徵

Evergreen trees; twigs dark brown, terete, young twigs brown, puberulous and densely to sparsely pilose to glabrescent; terminal buds subulate, 3–6 mm long, apex often curved, puberulous and densely to sparsely pilose.
Leaves coriaceous, elliptic to narrowly elliptic, rarely ovate, 4–8 cm long, 2–4(–5) cm wide, apex caudate, with apiculate tip, base cuneate-attenuate, margins slightly recurved, crenate-serrate with teeth, teeth 2–5(–7) mm apart, both surfaces glabrous, or sparsely hairy on midrib on lower surface, midrib impressed on upper surface, prominent on lower surface; nerves 5–7(–8) pairs, slightly prominent on both surfaces; reticulation fine, often slightly prominent on both surfaces, petiole glabrous, or puberulous and/or sparsely pilose, 5–8 mm long.
Inflorescences axillary, a simple racemes, 5- to 10-flowered, 1–3(–4) cm long, axis and pedicels pilose, often with minutely bristly hairs, pedicels 1–4(–8) mm, bracts gradually changing from upwardly from orbicular at base to obovate at top, apex obtuse and abruptly acute, meniscoid to boat-shaped, 2–3 mm long, caducous, glabrous adaxially inside, appressed pubescent abaxially outside, margin ciliate, bracteoles 2, narrowly elliptic to lanceolate, boat-shaped, 1.5–2 mm long, apex acute, margin ciliate, often glandular denticulate near base, glabrous adaxially inside, with same indument as bracts abaxially outside. Calyx tube glabrous, 1–1.5 mm long, limb 1–2 mm long, lobes ovate to narrowly ovate, 1–1.5 mm long, apex acute or obtuse; appressed pubescent outside at least near apex; corolla white, deeply 5-lobed, 3–4 mm long, lobes elliptic; stamens 35–60, connate at base; disc annular, glabrous; style glabrous, 4–5 mm long, ovary 3-locular, with 4 ovules 4 perin each locule.
Fruits ampulliform, 5–7(–10) mm long, 3–4(–5) mm in diam., crowned by persistent calyx lobes, stone ampulliform, smooth to slightly grooved, mesocarp thin, seed 1, curved, with curved embryo.
At higher elevations, plants with nerves impressed on the upper surface of leaves (S. macrostroma Hayata) occur, but appear to represent an ecological form on the wind-exposed ridges.
