Characteristics

Sprawling or very rarely somewhat erect, sympodial, annual herbs, 0.03-0.25 m tall. Stems herbaceous, immaculate, usually very well-branched at base; branches prostrate to decumbent or rarely somewhat ascending to erect, not sprouting from the nodes. Leaves 15-60 x 6-20 mm, glabrous or scabrid, 2-pinnate, herbaceous to somewhat coriaceous; ultimate leaflet segments linear-oblong, 1-10 x < 1 mm, laminate to subterete, concolorous, green or glaucous, margins entire, venation visible. Petioles 7-30 mm long, glabrous or scabrid. Umbels shortly pedunculate, very rarely sessile to subsessile, peduncles (0-)6-30 mm long; involucral bracts 1 to 6, lanceolate to ovate or often foliose, coriaceous, acuminate, margins membranous, glabrous or scabrid; rays 4 to 12, 5-15 mm long, glabrous or scabrid; involucel bracts 2 to 6, linear to lanceolate, coriaceous, acuminate, margins often membranous, glabrous or scabrid; raylets 4 to 12, 2-5 mm long, glabrous or scabrid. Flowers with petals 0.7-1 x 0.7-1 mm, deeply emarginate, papillose; ovary scabrid to pustulate; styles lengthening as fruit matures, 0.7-1.3 mm long, becoming reflexed and extending well beyond base of stylopodium and often beyond base of fruit. Fruit 0.6-1.8x1.0-1.8 mm, transversely oblong (broader than long), base cordate; mericarps homomorphic, scabrid to pustulate; median and lateral ribs as well developed as marginal ribs, slightly prominent, cartilaginous, dorsal surface without fibrous ridges, scabrid to pustulate; marginal ribs strongly concave in lateral view.
