Bucklandia tonkinensis Lecomte, Bull. Mus. Hist. Nat. (Paris) 30: 392. 1924; Symingtonia tonkinensis (Lecomte) Steenis.
Trees to 30 m tall; young branches brown pubescent, glabrescent. Stipules narrowly oblong, 2–4 × 0.8–1.3 cm, puberulent; petiole 3–5 cm, glabrescent; leaf blade broadly ovate or sometimes palmately 3-lobed in young leaves, 8–13 × 5–9 cm, dark green, abaxially glabrous and tuberculate, adaxially shiny, base broadly cuneate, margin entire or palmately 3-lobed in young leaves, apex acuminate, palmately 3–5-veined. Inflorescences capitate, sometimes arranged in racemes; heads 7–9-flowered; peduncle 1–1.5 cm, brown tomentose. Petals absent. Stamens ca. 13, ca. 8 mm. Ovary yellow-brown pubescent; styles 4–5 mm. Capsules ovoid, 10–15 × 8–10 mm, tuberculate. Seeds 6, winged at lower part, 8–10 mm. Fl. May–Jul, fr. Aug–Sep.
Slopes and valleys in evergreen forests; 800--1500 m. Fujian, Guangdong, Guangxi, Hainan, S Hunan, Jiangxi, SE Yunnan [Laos, N Vietnam].
This combination was first published by Steenis (Blumea 7: 595. 1954), but not validly, because the place of publication of the basionym, as required by the ICBN since 1953 (St. Louis Code, Art. 33.3), was not cited.
