Description:
Andromonoecious trees ca. 7–9 m tall, well branched above the middle. Leaves pinnately compound, 28–57 cm long, densely rusty brown to tawny farinose stellate pubescent throughout except on the upper surface of the leaflets; petiole 7–17 cm long, stout, ca. 4–8(–10) mm in diameter at the base; rachis articulated at the petiolule bases; petiolules of lateral leaflets (2–)5–22 mm long, those of the terminal leaflet (17–)20–50 mm long; leaflets 5 to 9, narrowly ovate to elliptic, 4–8 x (5.5–)7–17 cm, the lowermost pair sometimes reduced, lamina glossy green and glabrous above, often with a whitish scurf, midvein yellow-green, farinose stellate pubescent below with evident yellow-brown venation, apex acute to nearly rounded, margin entire, minutely revolute, base acute to rounded or sub-cordate, usually oblique on the lateral leaflets. Inflorescence axillary, paniculate-umbellate, pendant, densely brown farinose stellate pubescent throughout, primary axis stout, (5–)6–13 cm long, secondary axes (2 or)3 to 6, 2 to 4 terminal and (0 or)1 or 2 inserted laterally along the primary axis, the uppermost secondary axes (peduncles) 6–10 cm long, bearing ca. 10 to 15 hermaphrodite flowers, ca. 3 to 8 forming a terminal umbellule and the others scattered along the axis, the lowermost generally abortive and leaving an evident scar, the lower secondary axes (when present) sometimes further divided, 13–15 cm long, with 10 to 12 tertiary axes (peduncles) bearing ca. 7 to 15 apparently staminate flowers, 3 to 6 forming a terminal umbellule and the others borne mostly in the distal half, many early abortive and leaving an evident scar, pedicels stout, 2–7 mm long, ca. 3–4 mm in diameter in hermaphrodite flowers, ca. 2 mm in diameter in staminate flowers. Calyx cupuliform, shallow, ca. 1 mm high at anthesis, expanding to ca. 2 mm in fruit, irregularly undulate. Corolla depressed-rounded to broadly obtuse or nearly triangular in bud, petals 10 (or 11), sometimes remaining united in pairs at anthesis and appearing fewer in number, lanceolate-triangular, yellow-green, fleshy, coriaceous when dry, densely farinose stellate pubescent on the dorsal surface, glabrous within, in hermaphrodite flowers 5–6 mm long in bud expanding to 8–12.5 mm at anthesis, smaller in staminate flowers, up to 4–5 mm at anthesis. Stamens 10 (or 11), in hermaphrodite flowers the filaments thick, ca. 4 mm long, the anthers 3–3.5 mm long, in staminate flowers the filaments 2–2.5 mm long, the anthers 2.5 mm long. Ovary 5-carpellate, obconic in bud, becoming somewhat urceolate at anthesis, especially in hermaphrodite flowers, surmounted by a concave nectar disk tapering into a stout column of 5 fused styles, ca. 1–2 mm long at anthesis, expanding to 4 mm in fruit, crowned by 5 sessile stigmas. Mature fruit urceolate, 15–20 mm high, 10–16 mm wide near the middle, 10–12(–16) mm wide distally, with a distinctly expanded calyx rim; nearly mature seeds tan-brown, ovate to elliptic-compressed, broader at base, 11 x 7 mm.
