Description: 

Genus: "Trees, shrubs, or herbs, often with extrafloral nectaries on leaf petioles and/or raceme axes; leaves spirally arranged or distichous, paripinnate, the leaflets opposite (numerous and small in our taxa); inflorescences 1-many-flowered, racemose, the axis sometimes adnate to stem, the pedicels 2-bracteolate near or above middle; flowers with 5 sepals, imbricate; petals 5, nearly always highly heteromorphic, yellow (sometimes red-marked near claw), the 2 abaxial ones variously oblique, the vexillar one usually interior in bud but sometimes exterior on one or both sides; androecium functionally (2-) 5-10-merous, essentially actinomorphic, the filaments straight, short, the anthers basifixed, equal or unequal (if unequal not accrescent toward abaxial side of flower), puberulent or pilosulous along lateral sutures, dehiscent by pores or short slits apically; fruit plano-compressed, very rarely winged along sutures, elastically dehiscent, the valves coiling, papery, leathery, or subligneous, the seed funicle deltately dilated, the seeds with a smooth or pitted testa, without areoles"  (Smith, 1985; pp. 117-118).

Genus: "Stipules lanceolate, usually 5-15 mm long and prominently 5-13-nerved; leaves with petioles 3-7 mm long, the gland variable but usually slightly elevated (depressed in center) and 0.5-1 mm in diameter, sometimes obovoid-stipitate; leaf rachis sulcate, the margins of furrow not raised between leaflet pairs and appearing only narrowly winged; leaflets 10-26 (-31) pairs, the blades usually 10-23 x 2-3 mm and with venation evident on both surfaces; seeds nearly as broad as long" (Smith, 1985; pp. 117-118).

C. mimosoides (similar species): "Stipules acicular to lanceolate, usually 3-10 mm long and with only 1-3 nerves in distal portion; leaves with petioles 1-3 mm long, the gland flat, discoid, 0.3-1 mm in diameter; leaf rachis seemingly serrate, the margins of furrow slightly expanded between leaflet pairs into rounded wings; leaflets 15-40 (-80) pairs, the blades usually 2-8 x 0.5-1.5 mm and with venation often immersed or obscure on upper surface; seeds about half as long as broad"  (Smith, 1985; pp. 117-118).

Habitat/ecology:  In Fiji, "abundant locally as a weed along roadsides and in cultivated areas, sometimes in coconut plantations" (Smith, 1985; pp. 117-118). In Guam, "a rather uncommon roadside weed" (Stone, 1970; pp. 310-311).  In Hawai‘i, "naturalized in dry to mesic, disturbed sites, 3-1,130 m"  (Wagner et al., 1999; pp. 655-656).

Propagation:  Seed

Native range:  Neotropics, now widely naturalized (Wagner et al., 1999; pp. 655-656).
