Shrub or tree up to 8 m. tall, much-branched, all parts glab. Seedlings with simple ovate serrate lvs passing quickly into stage (a), succeeded by stage (b) or directly by adult stage, rarely remaining simple-lvd to adult stage. Juveniles of stage (a) with lvs 3–5-foliolate, lflts 4–15 cm. long, narrow linear-oblong to elliptic, deeply lobed to pinnatifid, lobes acute to obtuse; petioles up to 10 cm. long. Juveniles of stage (b) with lvs 3–5-foliolate, lflts 5–8 cm. long, elliptic to obovate-oblong, to lanceolate, acute or obtuse, sharply to bluntly serrate, on petioles up to 6 cm. long; sts flowering at this stage. Adults with unifoliolate lvs, with or without some trifoliolate lvs; lamina lanceolate to broad-lanceolate, to elliptic, to ovate-elliptic, to obovate-oblong, sharply serrate, acuminate to acute or obtuse, coriac., 5–10 cm. or more long, on petioles 3–8 cm. long. Umbels axillary and terminal on peduncles c. 2–3 cm. long, compound with 3 or more umbellules each 5–15-fld; terminal umbellule us. completely pistillate, lateral wholly or partly staminate.
