備註: 烏檀頂芽兩側壓扁. 團花托葉三角形 東方烏檀: 葉片約15-30 x 10-18cm; Fruiting heads (i.e., multiple fruit), 0.9-1.5 cm diam 烏檀:葉片約7-11[-15] × 3.5-7[-10]cm; Fruits about 4-5 cm diam (東方烏檀的話葉大很多) loc in internal reference 同團花Neolamarckia cadamba 的葉有些似 FOHK: Evergreen trees, 4–12 m tall. Branchlets slender, smooth; terminal bud obovoid. Stipules obovate, 6–10 mm, apex rounded, caducous. Leaves opposite, papery; petioles 10 – 15 mm; leaf blade elliptic, rarely obovate, 7–9 × 3.5–5 cm, base cuneate, apex acuminate, tip ± blunt, glabrous; lateral veins slender, 5–7 on each side of midvein, slightly raised on both surfaces. Flowering head solitary, terminal. Peduncles 1–3 cm. Calyx‑tubes connate, fleshy. Corolla funnel‑shaped, 5‑lobed. Stamens 5, inserted in the upper part of the corolla‑tube. Fruiting head globular, yellowish brown when ripen, 9–15 mm in diam., composed of numerous drupelets. FOC: Trees, apparently evergreen, to 12 m tall; branchlets angled and rather flattened becoming terete, puberulent to glabrescent. Petiole 10-15[-20] mm; leaf blade drying papery, elliptic to broadly elliptic or infrequently ovate or obovate, 7-11[-15] × 3.5-7[-10] cm, glabrous, adaxially dark brown and matte to shiny, abaxially pale brown and matte, base cuneate to obtuse, apex shortly acuminate with tip slightly blunt; secondary veins 5-7 pairs, usually with tiny foveolate domatia in abaxial axils; stipules caducous, obovate to elliptic, 6-10 mm, glabrous, smooth, rounded. Inflorescences terminal, puberulent to glabrous; peduncles 1-3.5[-4.5] cm, in lower part articulate, bearing caducous bracts 2-4 mm; flowering heads 1-3, 5-6 mm in diam. across calyces, ca. 15 mm in diam. across corollas. Calyx limb deeply lobed; lobes 5, oblanceolate to spatulate, ca. 1 mm, glabrescent, fleshy, rounded to subtruncate. Corolla color unknown, narrowly funnelform, glabrous outside and apparently inside; tube 3-4 mm; lobes 5, ligulate to elliptic, 1-1.5 mm, obtuse to rounded. Stigmas 1.5-2 mm, exserted for ca. 3 mm. Fruiting heads (i.e., multiple fruit) yellow, 9-15 mm in diam., fleshy, with surface rough (i.e., pitted with calyx limb scars); seeds ca. 1 mm, with testa shiny black, foveolate. Fl. summer, fr.
