"Shrub, 1.5-4 m high.  Bark smooth, brown to grey.  Branchlets brown to reddish, terete, lenticular, glabrous.  Stipules persistent, white, spinose, subulate, 4-28 mm long, glabrous.  Leaves bipinnate.  Pulvinus 1-3 mm long, glabrous.  Leaf rachis 5-55 mm long, 1-4 pairs of pinnae per leaf, hairy on grooved upper surface, jugary glands present, interjugary glands absent; pinnae 6-32 mm long, 5-14 pairs of leaflets per pinna; leaflets linear-oblong, flat, 5.5-10 mm long, 2-3.2 mm wide L/W 2.8-4.3, concolorous, glabrous.  Inflorescences on simple axillary peduncles.  Heads globular, yellow, 10-11 mm wide; peduncle 10-28 mm long, hairy.  Pods stipitate or sessile, dark brown, paler on sutures, linear to oblong, straight or curved, cylindrical, indehiscent, 40-70 mm long, 8-12 mm wide, glabrous, longitudinally wrinkled, apiculate.  Seeds oblique in pod, olivaceous, irregularly ellipsoid, 6-9 mm long, 4.5-5.5 mm wide" (Dunlop et al., 1995).

"Erect much-branched shrub; leaves with 4-8 pairs of pinnae, pinnae with 10-12 pairs of small leaflets; stipular thorns straight and slender; flowers in pedunculate axillary heads, 1-3 heads together, subglobose; flowers yellow, fragrant; heads about 1.3 mm across; stamens numerous; pods dark brown or black, up to 8 cm long, to 12 mm broad, plump, often slightly curved; pulp within sweetish; seeds compressed, elliptic, brown"  (Stone, 1970; p. 296).

"Arbuste de 1 à 4 m de hauteur, reconnaissable à ses feuilles composées de 1 à 7 paires de pennes divisées chacune en 8 à 25 paires de petites folioles, ses grandes épines, ses inflorescences globuleuses (glomérules) de petites fleurs de couleur jaune vif, et ses gousses de 2 à 8 cm de long" (Meyer, 2008; p. 30). Dry habitats between sea level and 1000 m.  "This thorny, deciduous shrub grows to 4 m in height, sometimes forming impenetrable thickets, although in most areas it forms a more open cover. Although the aerial portions may be killed by fire, it soon regenerates from basal shoots"  (C.W. Smith, 1985; p. 183). "Sweet acacia is a drought-hardy, fire-resistant species that does not tolerate frost and grows well in areas receiving between 500 and 750 mm of rainfall with a dry season of 4 to 6 months (Webb and others 1980). Its best growth occurs on well-drained soils. It tolerates heavy clays to sands and a variety of soil conditions, including saline soils, at elevations up to 2,000 m. A light-demanding species, sweet acacia often forms dense thickets on disturbed sites and is associated with numerous other shrub and tree species in secondary thorn woodlands, shrublands, and dry forests in its tropical and subtropical American range (Rzendowski 1981)"  (Wildland shrubs of the United States and its territories).

In Fiji, "naturalized near sea level along roadsides, in cultivated areas and pastures, and on beaches and dry river banks " (A.C. Smith, 1985; pp. 69-70).  In Hawai‘i, "formerly cultivated for an attempted perfume industry, now naturalized and common, sometimes becoming a pest, in dry, open, disturbed areas, 2-400 m (Wagner et al., 1999; p. 641).

"Elle est devenue envahissante en Australie et dans les îles du Pacifique (Hawaii, Fidji, Guam, Nouvelle-Calédonie et Polynésie française) où elle forme des fourrés très denses dans les zones sèches et littorales, les zones cultivées et les pâturages" (Meyer, 2008; p. 30). In New Caledonia, "planté jadis par des éleveurs qui l'estimaient comme fourrage de réserve utile en temps de sécheresse. Toujours commun, surtout sur la côte Ouest" (MacKee, 1994; p. 76); "naturalisé autour de Nouméa" (Balansa 315, 1868, cited in MacKee, 1994; p. 76). Seeds are dispersed by ungulates which eat the pods. "Natural reproduction is abundant, particularly on disturbed sites and in active pastures where cattle readily consume the pods"  (Wildland shrubs of the United States and its territories).

"Ses gousses sont consommées par les animaux herbivores qui disséminent les graines" (Meyer, 2008; p. 30). Tropical and subtropical Americas; widely cultivated & naturalized, exact native range obscure (GRIN).

An invasive species in Fiji, French Polynesia, New Caledonia, Solomon Islands, and Vanuatu (Waterhouse, 1997). Reported by Waterhouse (1997) to be present in Niue but not seen there. "La lutte manuelle par arrachage des plantules et coupe des arbustes associée à une lutte chimique par traitement des souches avec un herbicide (à base de triclopyr et/ou dicamba) sont réalisables" (Meyer, 2008; p. 30).

Physical: "Destroyed by cultivation and grubbing." (Swarbrick, 1997)

Chemical: "Probably susceptible to: 1) translocated herbicides, including picloram, metsulfuorn-methyl, glyphosate and triclopyr, and possibly 2,4-D applied to the foliage, freshly cut stumps or by stem injection at standard rates; 2) residual herbicides, including tebuthiuron and hexazinone" (Swarbrick, 1997).

"Sensitive to foliar applications of triclopyr at 1 lb/acre and metsulfuron at 0.45 oz/a and to basal bark applications of 2,4-D or triclopyr at 2% in diesel. Drizzle applications were not effective in foliar and basal bark trials at Kihei, Maui, but these trials were confounded by a severe drought" (Motooka et al., 2003).
