Ultimate leaflets 2-or 3-sect; segments linnear, 20-30 mm x ± 1.5 mm, concolorous, glabrous; margins and midrib prominently thickened; extending into a sharp point. Synflorescences ca. 0.45 m long, with terminal primary umbel subtended by 10 slightly smaller, secondary and tertiary umbels; peduncle brownish, glabrous, nodes subtended by reduced scale-like peduncular bracts. Umbels compound, obtriangular in outline; involucral bracts 3 to 5, 3-5 mm long, lanceolate, acuminate, glabrous, caducous; rays 2 or 3, 80-95 mm long, equal, sub-erect, glabrous; involucel bracts 4 to 6, 1.5-2 mm long, lanceolate, acuminate, glabrous, raylets 9 to 14, glabrous, 2-3 mm long.

Fruits (immature) isodiametric, very narrowly elliptic in dorsal view, 3.5-4.0 mm x ± 1.5 mm; mericarps homomorphic, glabrous, immaculate when dry; median and lateral ribs 3, equal, inconspicuous; marginal ribs 2, inconspicuous; vascular tissue observed at base of ribs only; ribs without lignification; commissural vittae 2; vallecular vittae 4; commissure narrow; carpophore bipartite; druse crystals present, scattered throughout mesocarp.
