 Description

Stems filiform, branching, creeping, rooting at nodes, up to c. 3 dm. long, forming large patches. Lvs clustered at nodes, 3-foliolate, on slender petioles up to c. 8 cm. long; stipules ciliate; lamina membr. to subcoriac., glab. or nearly so, occ. with sparse strigose hairs. Lflts ± 15 × 10 mm., on petioles c. 3mm. long, broad obovate-oblong to obovate-cuneate; 2–6-lobed or obtusely toothed towards apex, occ. apiculate. Peduncles us. 2–3 together, filiform, ± 1–2–(3) cm. long. Umbels 2–8-fld; involucral bracts narrow-triangular to linear-oblong. ciliate. Fr. subtetragonous, > pedicel.
