Description: Hermaphroditic (or possibly andromonoecious) trees (2–)3–15 m tall. Leaves 50–100 cm long; leaflets 13–21(–25), papyraceous to thinly coriaceous, narrowly oblong-ovate to elliptic-ovate (the lowermost 1–2 pairs often widely elliptic-ovate), the lateral ones often strongly oblique to nearly falciform, 11–25 × 3.5–10(–12)cm, the apex narrowly acute to acuminate or cuspidate, the margin entire and minutely revolute, the base rounded or truncate to shallowly cordate and often strongly oblique; petiolules stout, 2–40(–50) cm long ; rachis articulated at petiolule bases; petiole stout, 10–30(–35) cm long, enlarged and clasping at the usually lenticellate base, evidently alate for 5–14(–20) cm with coriaceous to membranous, occasionally revolute wings. Inflorescence terminal, erect, glabrous throughout, the primary axis stout, often lenticellate, (15–)40–150 cm long, secondary axes 3–8(–10), scattered or irregularly grouped, (10–)30–90 cm long, each subtended by a coriaceous, adaxially concave, triangular to ovate-lanceolate, acute to acuminate bract 15–40 cm long, the tertiary axes ca. 20–50 per secondary axis, scattered or irregularly grouped, each 5–23 cm long at maturity, subtended by a coriaceous, adaxially concave, ovate to ovate-lanceolate, acuminate bractlet 2–20 mm long, and bearing ca. 25–40 scattered, racemosely disposed umbellules, the peduncles 0.5–6 mm long (or occasionally sub-sessile), each subtended by a small, lanceolate-subulate, acute to acuminate bractlet 0.5–2.5 mm long, and bearing (1–)2–10 hermaphroditic (or occasionally some apparently functionally staminate), protandrous flowers, the pedicels 0.2–1.2mm long (or the flowers sometimes sessile). Calyx broadly cupuliform, 0.2–0.4(–0.6) mm high, the rim undulate and often irregularly 5-denticulate, hyaline. Corolla oblong-elliptic to sub-globose and often tinged pinkish in bud, the petals 5, spreading to recurved at anthesis, greenish white to pale yellow, ovate to oblong-ovate, 1.8–2.5 mm long. Stamens ascending at anthesis, the filaments 0.5–0.8 mm long, the anthers white to pale yellow, 0.8–1.5 mm long. Ovary 2-carpellate, broadly urniform, 0.6–0.8 mm high at anthesis; styles 2, united only in the basal 1/3, 0.4–0.6 mm long and with the free arms erect at anthesis, diverging and expanding slightly as they become receptive, then recurving and elongating in fruit to 0.6–1.5 mm long. Mature fruit laterally compressed, purple, elliptic, orbicular or oblate to depressed ovate, 2.8–5.5 mm high, 3–6 mm wide, ribbed when dry, the base obtuse to truncate.
