Synflorescences 300-350 mm long, with terminal primary umbel subtended by 1 to 4 slightly smaller secondary umbels; peduncles slender, densely lanate in upper and lowermost portions; peduncular bracts 2-3 mm, lanceolate. Umbels compound, 20-40 mm in diameter; involucral bracts 4 to 6, 2-2.5 mm long, lanceolate, acuminate; rays 5 to 12, 20-30 mm long at anthesis, glabrous, involucellar bracts 3, 2-3 mm long, lanceolate, acuminate, glabrous; raylets 5 to 9, 2-3 mm long at anthesis, glabrous; umbellules with 1 or 2 bisexual flowers surrounded by 3 to 6 functionally male flowers. Flowers with 5 large, petaloid sepals, ca. 1.5 mm long, elliptic, apex acute, cream-coloured, veins 3, usually prominent; petals filiform, strongly inflexed, cream-coloured. Fruits ovate, base rounded, strongly dorsally compressed, 3-4 mm x 2.5-3 mm; mericarps homomorphic, glabrous; marginal, lateral and median ribs inconspicuous, with a prominent wing between the lateral and marginal ribs.

Leaves simple, on slender petioles, in basal clusters, proteranthous; petiole 30-110 mm, glabrescent; lamina ovate-elliptic, pinnatipartite (rarely pinnatifid), (20-)40-(35) x 15-25(-52) mm; base variably cuneate to cordate; apex mucronulate; margin cleft, the lobes dentate; adaxial surface green, glabrous; abaxial surface gray-white, densely tomentose; veins prominent, reticulate. Inflorescence with 1 to 4 umbels; peduncle slender, 300(-350) mm, densely woolly at the base; bracts on peduncle lanceolate, ±3 x 1 mm, revolute; umbel small, each with 5 to 12 umbellules; umbellule with 1(to 2) bisexual flowers surrounded by (3 to)6 male flowers; bracteoles paired; sepals large, petaloid, veins single in keel; petals filiform. Fruit ovate, dorsally strongly compressed, ±4 x 3 mm; lateral wings absent, marginal ribs inconspicuous, dorsal ribs inconspicuous or absent, endocarp woody. Flowering occurs from December to February and fruiting from February to April.
