形態特徵

• A shrub or small to rather large tree.
• Leaves l-foliolate, 4–30 cm long; petiole 0.5–5 cm long; leaflet blade glabrous, elliptic or elliptic-oblong to obovate or oblanceolate, 3.5–24.5 cm long, 2–8.5 cm wide, the base cuneate or sometimes rounded or attenuate, the apex obtusely acuminate or sometimes obtuse or rounded.
• Inflorescences few- to many-flowered, 2–25 cm long. Sepals 0.6–1.5 mm long; petals 3–11 mm long; ovary pubescent (rarely only at apex), 4-carpellate, completely syncarpous or with apical septicidal fissures; style pubescent toward base.
• Fruit usually rather sparsely pubescent and with a ring of dense, appressed hairs at base, but grading to tomentose or glabrous, completely syncarpous or with apical septicidal fissures, usually subglobose but grading to ellipsoid, pyriform, or broadly conical, sometimes lobed or ribbed, 5–15 mm wide, the epicarp drying 0.5–3 mm thick, with woody or subwoody mesocarp. Seeds 3–7 mm long.
• As seen in Taiwan, <i>Acronychia pedunculata</i> has leaves about 7–15 cm long with the leaflet blade about 6–12 cm long and 2.5–5 cm wide. The petals are about 5–6 mm long and the fruit, which is pubescent or sparsely so, is about 7–8 mm wide.
