Shrubs, 0.2-0.4 m tall. Stem repeatedly branched, branches glabrous. Leaves regularly arranged along the upper parts of the branches, 10-18 mm x 10-15 mm; blade broadly ovate, 2-pinnate. Ultimate leaflet segments elliptic or obovate to broadly obovate, 5-13 mm x 3-7 mm, 2-or 3-cleft or 2 lobed; base attenuate; venation pinnate; concolorous, green; lobes very narrowly elliptic, flat, 2-5 mm x 1-2 mm, margins entire, prominently revolute (folded over to a width of 0.5 mm). Petioles to 2 mm long, sheathing along their entire length. Inflorescence long (more than two times longer than the diameter of the primary umbel), with 0-3 smaller lateral umbels. Primary umbel with 7-8 rays, flat-topped; bracts lanceolate, apex acute to slightly acuminate, glabrous; rays 5-8 mm long, unequal, glabrous; bracteoles lanceolate, apex acute to slightly acuminate, slightly scabrous, usually shorter than raylets; raylets scabrous. Flowers with sepals relatively large, 0.4-0.7 mm, apex obtuse to acute, glabrous; petals unknown. Fruit broadly elliptic to rotund, 5 mm x 4 mm; mericarps homomorphic; median and lateral ribs obsolete or very slightly prominent; marginal ribs relatively broadly-winged; commissural vittae narrow; vallecular vittae narrow.
