Deciduous geophyte. Root 1?, pencil-like, slightly and evenly fleshy. Leaves in basal rosette, procumbent, dead at time of flowering, 15-30 x 12-20 mm, 3-to 5-ternate; rachis and pinnae prominently refracted. Ultimate leaflets 2-or 3-partite, 5-22 mm x 3-10 mm; segments ovate to lanceolate, 3-20 x 1-4 mm, concolorous, glabrous; margins and midrib thickened and extending into a sharp point. Synflorescences 0.14-0.5 m long, with terminal primary umbel sometimes subtended by 1 to 4 smaller, secondary and tertiary umbels, peduncle brownish, glabrous, nodes subtended by reduced scale-like peduncular bracts. Umbels compound, transversely ovate or sometimes shortly obtriangular; involucral bracts 2.5-3 mm long, 3 to 4, narrowly oblong, acuminate, glabrous; rays 3 to 5, 15-30 mm long at anthesis, ± equal, spreading or sometimes sub-erect, glabrous; involucel bracts 4 to 6, 1-1.5 mm long, narrowly oblong, acuminate, glabrous, raylets 10 to 18, glabrous, 3-7 mm long at anthesis. Flowers hermaphroditic in terminal and secondary umbels, functionally male in tertiary umbels; calyx lobes 5, acute; petals 5, yellow, 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 reflexed to just above the base of the stylopodium. Fruits isodiametric, elliptic to narrowly ovate in dorsal view, 4.0-5.0 mm x 2.5-3.5 mm; mericarps homomorphic, glabrous, immaculate when dry; median and lateral ribs 3, equal, filiform; marginal ribs 2, broadly winged, flexuose, margins slightly sinuous; vascular tissue at base of ribs only; ribs with most cells slightly lignified; commissural vittae 2; vallecular vittae 4; commissure narrow; carpophore bipartite; druse crystals present, scattered throughout mesocarp.
