Slender to robust shrub, 1-2.5 m tall. Stem solitary, sparsely branched above ground level, branches glabrous. Leaves regularly arranged along the upper parts of the branches, 90-250 mm x 60-150 mm; blade broadly ovate, 2-pinnate. Ultimate leaflet segments rhomboid to obovate, (20)40-65(85) mm x (12)20-50(70) mm, 3-lobed to 3-partite, usually regularly toothed over upper half or two thirds; teeth prominent; margins irregularly serrate or less often lacerate; base cuneate to obtuse, often asymmetrical; lamina not revolute along the margins; venation clearly reticulate; discolorous, adaxial surface green, occasionally covered with a fine bloom, abaxial surface glaucous. Petioles up to 25(40) mm long, sheathing at the base only. Inflorescence short (less than 1.5 times as long as the diameter of the primary umbel), rarely with 2 smaller lateral umbels. Primary umbel with (30)52-120(180) rays, orbicular; bracts linear to lanceolate, apex acuminate, glabrous; rays (32)39-76(102) mm long, subequal, glabrous; bracteoles linear to lanceolate, apex acuminate, glabrous, usually shorter than raylets; raylets glabrous. Flowers with sepals small, 0.1-0.3 mm long, glabrous; petals glabrous. Fruit elliptic to rotund, 3.5-6.0 mm x 2.5-3.5 mm; mericarps homomorphic; median and lateral ribs obsolete or slightly prominent; marginal ribs narrowly-winged; commissural vittae broad; vallecular vittae broad; additional vittae under vascular bundles in ribs, smaller than vallecular vittae.
