Ultimate leaflets 2-or 3-sect; segments linear, 15-50 mm x 1-2 mm, concolorous, glabrous; margins and midrib thickened and extending into a sharp point. Synflorescences 0.45-1.0 m long, with terminal primary umbel subtended by 1 to 5 smaller, secondary and tertiary umbels; peduncle brownish, glabrous, nodes subtended by well developed foliose peduncular bracts. Umbels compound, obtriangular in outline; involucral bracts 3 or 4, 4-7 mm long, ovate to broadly oblong, acuminate, glabrous; rays 3 to 6, 25-55 mm long at anthesis, ± equal, sub-erect, glabrous; involucel bracts 5 or 6, 3.5-4 mm long, ovate, shortly acuminate, glabrous, raylets 10 to 18, glabrous, 2-3 mm long at anthesis. Flowers hermaphroditic in terminal and secondary umbels, functionally male in tertiary umbels; calyx lobes 5, truncate; petals 5, cream?, broadly ovate to broadly elliptic, acuminate with tips inflexed, glabrous, resin duct conspicuously branched, lateral branches 2-5, arising from near the base of the central duct; stamens 5, with anthers inflexed; ovary bilocular, glabrous; stylopodium shortly conical; styles at first erect, later becoming somewhat reflexed.
