Description:  "Shrublets or annual herbs, (15-) 30-100 (-150) cm tall. Stems erect, many branched, cylindric, hollow, glabrous, corky at base, often with nodule-bearing adventitious roots. Stipules elliptic to lanceolate, 4-11 x 1-2 cm, membranous, caducous, base auriculate, apex acuminate. Leaves 20-60-foliolate, often sensitive; petiole 2-4 mm; rachis with tuberculate-based trichomes; leaflet blades linear-oblong, 3-13 x 1-3 mm, papery, base oblique, apex obtuse and mucronate. Inflorescences axillary, racemose, sometimes short or reduced to a solitary flower; peduncle 4-7 mm, with tuberculate-based trichomes; bracts ovate, caducous, margin often denticulate. Bracteoles ovate-lanceolate, persistent. Calyx 3-4 mm, membranous, glabrous. Corolla pale yellow with purplish longitudinal striations. Legume linear-oblong, 2.2-3.4 cm x 3-5 mm, straight, herbaceous to leathery, abaxial suture straight, slightly indented; articles 2-8, quadrate, slightly muricate and with tuberculate-based trichomes. Seeds blackish brown, reniform, ca. 2 mm"  (Flora of China online).

"An erect herb with imparipinnate leaves, branching, with scattered spreading hairs on stems, rachises, and peduncles; leaves 5-10 cm long; stipules semisagittate, about 1 cm long; leaflets numerous, 15-30 pairs, linear-oblong, glaucous beneath, 10-15 mm long, rounded at tip; flowers few in racemes, pale yellow; pedicels with 2 bracteoles at base of calyx; bracts like the stipules; flower c. 1 cm long; calyx bilabiate, deeply cleft; pods linear, flat, 6-8-jointed, with a central prominent rugosity on each joint"  (Stone, 1970; p. 322).

Habitat/ecology:  "Most frequently found in poorly drained areas, wet pastures, along rivers and canals, and in or around paddy fields"  (Holm et al., 1997: p. 20).  In Guam, "found in man-disturbed areas and thickets, not common."  (Stone, 1970; p. 322).  In Fiji, "occurring as a weed from near sea level to low elevations on gravel banks of rivers, along roadsides, in waste places, and often in wet parts of ricefields and canefields" (Smith, 1985; pp. 257-258). In New Guinea, "a plant of wet situations; stream banks, swamp margins, roadside ditches, and sometimes as a weed in pastures. Widely distributed from low altitudes to 800 m" (Henty & Pritchard, 1975; p. 111).

Propagation:  Seed

Native range:  Probably native to America (Smith, 1985; pp. 257-258), exact native range obscure (GRIN).
