形態特徵

• A shrub or small to medium tree. Young branchlets glabrous to pubescent, 2–10 mm wide in third internode.
• Leaves opposite, 3- and/or l-foliolate. Three-foliolate leaves 5–51 cm long; petiole 1–15 cm long; leaflet blades pubescent on venation below and midrib above or grading to glabrous, elliptic to obovate or oblanceolate, 3–34.5 cm long, 1.5–15 cm wide, the base acute to subattenuate, the apex rounded or emarginate to acuminate. One-foliolate leaves 6.5–19 cm long; petiole 1–3 cm long; leaflet blade elliptic-obovate or obovate, 5.5–16 cm long, 3.3–8 cm wide; otherwise similar to 3-foliolate leaves.
• Inflorescences axillary and sometimes on branchlets below leaves, several- to densely many-flowered, 1.5–9.5 cm long. Flowers unisexual (plants dioecious); sepals 0.5–1.3 mm long; petals white, greenish, or pale yellow, 1.5–3 mm long; stamens 4; ovary sericeous-pubescent, the carpels connate at base, 2-ovulate.
• Fruit of 1–4 basally connate follicles, these sparsely pubescent or glabrate, subglobose, 4–4.5 mm long, dehiscent to base. Seeds subglobose to ellipsoid, 2.5–4 mm long.
• As seen in Taiwan, <i>Melicope semecarpifolia</i> has pubescent young branchlets, and the leaves, which are exclusively 3-foliolate, also have indumentum, at least when young. The branchlets are about 5–8 mm wide in the third internode and the leaflet blades are about 11–22 cm long and 4.5–9 cm wide .
