Sprawling to prostrate (erect when young), sympodial, shortlived suffrutices, 0.10-0.4 m tall, resprouting. Stems woody, immaculate, at first simple becoming slightly to well-branched; branches decumbent to prostrate, sprouting at nodes. Leaves 15-100 x 10-40 mm, glabrous, pinnate to 2-pinnate, firm and semi-succulent; ultimate leaflet segments oblong, 1-4 x 1-3 mm, turgid or rarely laminate, usually strongly curled inwards, concolorous, glaucous or sometimes green, margins entire or toothed, venation usually obscure.. Petioles 5-40 mm long, glabrous. Umbels with peduncle short to long, 10-80 mm long; involucral bracts 4 to 6, lanceolate to ovate, slightly succulent, acute to acuminate, margins usually membranous, glabrous; rays 6 to 26, 8-32 mm long, glabrous or scabrid; involucel bracts 4 to 6, lanceolate, slightly succulent, acute to acuminate, margins often membranous, glabrous; raylets 6 to 14, 2-5 mm long, glabrous. Flowers with petals 0.8-1 x 0.8-1 mm, apex slightly to deeply emarginate, smooth; ovary glabrous; styles lengthening as fruit matures, 0.8-1.0 mm long, becoming reflexed and extending up to or beyond base of stylopodium. Fruit 2.5-6.0 x 3.0-5.0 mm, ovate to very broadly ovate in lateral view, base obtuse; mericarps homomorphic or heteromorphic, glabrous; if homomericarpic then with median and lateral ribs as well developed as marginal ribs, if heteromericarpic then with either median or lateral ribs as well developed as marginal ribs, very prominent to winged, corky, dorsal surface without fibrous ridges, glabrous; marginal ribs parallel in lateral view.
