Synflorescences 500-1,000 mm long, with terminal primary umbel subtended by 4 to 19 smaller secondary umbels; peduncles stout, sometimes felty and lanate when very young but soon becoming largely glabrescent; peduncular bracts 20-60 mm, oblong to foliose, densely felty and lanate. Umbels compound, 60-80 mm in diameter, dense; involucral bracts lanceolate, 10 to 12, 10-15 mm long, maroon to purple-black, venation parallel, adaxial surface glabrous to glabrescent, abaxial surface sparsely lanate; rays ca. 40 to 65, 15-25 mm long at anthesis, glabrous; involucellar bracts 2 to 4, 5-8 mm long; lanceolate, maroon to purple-black, glabrous to glabrescent; raylets 6 to 12, ca 2 mm long at anthesis, maroon to purple-black, glabrous; umbellules with 1 to 7 hermaphroditic flowers surrounded by 4 to 10 functionally male flowers. Flowers with 5 large, petaloid sepals, maroon to purple, veins 3, inconspicuous; petals filiform, strongly inflexed, maroon to purple. Fruits ovate, base truncate to cordate, dorsally compressed, ca. 2.0-2.5 x 1.5 mm; mericarps homomorphic, glabrous; marginal ribs inconspicuous; lateral ribs narrowly-winged; median rib prominent, narrow.
