形態特徵

• Small evergreen trees; twigs green to grayish dark brown, terete; young twigs green, conspicuously ridged below petioles, glabrous; terminal bud ovoid, apex acuminate, often curved, 3–10 mm long, glabrous except ciliolate margin of scales ciliolate.
• Leaves glabrous, elliptic or oblong, 3–9 cm long, 1–3 cm wide, apex shortly caudate, obtuse, base cuneate, margins recurved, crenate-serrate, with teeth 2–12 mm apart, midrib prominent on both surfaces, nerves 6–9 pairs, meeting in an intramarginal vein, slightly prominent on both surfaces, petiole glabrous, 3–10 mm long, sulcate on upper surface.
• Inflorescences axillary, a contracted spikes, branched like a paniculately branchedle, axis puberulous, ridged, to 1 cm long; bract persistent, semiorbicular to depressed ovate, 1.5–2 mm long, apex rounded, bracteoles 2, persistent, keeled, ovate, ca. 2 mm long, apex acute, with apiculate gland, glabrous or hairy along midrib, margin ciliolate. Calyx tube glabrous, 1.5 mm long, limb 1.5 mm long, deeply 5-lobed, lobes imbricate, ovate, apex rounded, 1.2–1.5 mm long, glabrous except ciliolate margin ciliolate; corolla white, 4.5–5.5 mm long, deeply 5-lobed, lobes elliptic, ciliolate; stamens 50–60; disc pilose; style glabrous, 5–6 mm long, ovary 3-locular.
• Fruits ellipsoid or obovoid, crowned by persistent calyx lobes, 9–13 mm long excluding calyx limb, 5–7 mm in diam., stone smooth, mesocarp woody, 3-locular, seed 1 in each locule, straight with straight embryo.
• Plants from Taiwan belonging to this species were previously referred to S. kuroki Nagam. (= S. lucida Sieb. & Zucc.), but they are easily distinguished by having more stamens and a 3-locular ovary. The epithet 'migoi' is selected after honors Hisao Migo
