Slender shrub, 1.6-2.0 m tall. Stem sparsely branched near ground level, branches glabrous. Leaves regularly arranged or often congested along the upper parts of the branches, 90-230 mm x 30-120 mm; blade narrowly ovate, 2-pinnate. Ultimate leaflet segments reduced to rigid, spine-tipped pinnules, linear, terete, 4-40 mm long; margins entire; glaucous. Petioles up to 40 mm long, sheathing along almost their entire length. Inflorescence long (more than two times longer than the diameter of the primary umbel), with large prominent sheathing leaf bases, with 0-6(8) lateral umbels. Primary umbel with (10)18-26 rays, slightly orbicular, congested; bracts lanceolate, apex acuminate, glabrous; rays 25-37 mm long, subequal, glabrous; bracteoles lanceolate, apex acuminate, glabrous, usually equal to or longer than raylets; raylets glabrous. Flowers with sepals small, 0.3-0.4 mm long, apex truncate to obtuse, glabrous; petals glabrous. Fruit broadly elliptic, 5.5-6.0 mm x 4.0-5.0 mm; mericarps homomorphic; median and lateral ribs obsolete to slightly prominent; marginal ribs narrowly-winged; commissural vittae broad; vallecular vittae broad; additional vittae under vascular bundles in ribs, smaller than vallecular vittae.
