Description:  "Small tree with prickly thorn-like stipules and small simple alternate 3-nerved leaves white (or tawny) tomentose beneath, dark green above, ovate or subelliptic, or slightly rhomboid, mostly less than 6 cm long, finely serrulate; flowers bisexual or male, greenish, in small cymes to 10 cm long; about 5 mm wide; calyx 5-toothed; petals 5; disc large; ovary with 2 styles; fruit a drupe with sweet sour mealy flesh and a 2-seeded stone, orange when ripe" (Stone, 1970; pp. 399-400).

Thorny tree 4-10 m high.  Flowers are white or greenish white and the fruits are orange to brown, 2-3 cm long, with edible white pulp surrounding a 2-locular pyrene. (Smith, 1985; pp. 696-697).

Habitat/ecology:  "Bush- and woodland, coastal sites.  A highly variable species with numerous varieties and cultivars and whose exact native range is obscure.  The shrub forms dense and impenetrable thickets affecting wildlife and displacing native plants.  In Australia, it forms a continuous shrub layer within formerly open eucalypt woodlands"  (Weber, 2003; p. 460).

In Fiji, "sometimes naturalized along roadsides and in agricultural land, usually near sea level but occasionally up to an elevation of about 600 m"  (Smith, 1985; pp. 696-697). "Occurs in a wide variety of habitats including river levees, margins of springs and alluvial flats.  Can spread to form impenetrable thorny tickets which seriously hamper the movement of animals and humans.  The thickets also out-compete more desirable native pasture species." (Smith, 2002; p. 25). In New Caledonia, "introduit depuis longtemps, reste rare dans les jardins" (MacKee, 1994; p. 120).

Propagation:  "Seed is spread by birds..., native animals, stock, feral pigs and humans who eat the fruit and expel the seeds. Spread also by intentional plantings as a fruit tree" (Smith, 2002; p. 25).  "The plant suckers from roots and resprouts even after complete removal of the shoots, e.g. after fires"  (Weber, 2003; p. 460).

Native range:  "Perhaps originally a native of India, Ziziphus mauritiana is apparently now widely naturalized from tropical Africa to Afghanistan and China, and also through Malesia and into Australia and some Pacific archipelagoes; its range as an ornamental is even more extensive" (Smith, 1985; pp. 696-697).

Comments:  Reported to be moderately invasive in Fiji (Meyer, 2000; p. 92). "A declared noxious weed in Western Australia, Queensland and the Northern Territory" (Smith, 2002; p. 25).

Control: 

Physical:  "Single plants can be slashed and the roots grubbed".

Chemical:  "Larger stands are slashed and the cut stumps treated with triclopyr.  Basal bark sprays with triclopyr or picloram are also effective.  Glyphosate can be used as an overall spray.  Follow-up programs are necessary to treat seedlings and regrowth"  (Weber, 2003; p. 460).
