Prosopis cineraria (Linn.) Druce. Description
An almost evergreen, thorny, large shrub, small sized tree 12 m tall. The crown is open and spreading. The stem is short with diameters up to 31 cm. Foliage is feathery-like and the leaves are compound, 1 to 2.5 cm long. Leaf fall occurs for short periods before flowering. The bark is rough, grey, and exfoliating in thin flakes. The flowers are small, creamy white to pale yellow and are arranged in small bunches, 1 to 2.5 cm long, flowering between December and May. The pods are flat, 12 to 25 cm long and contain on the average 10 to 15 seeds, maturing between April and August. A number of insects attack it, but they are of little significance. It is reproduced both from seed and by vegetative means. The seed can be stored for long periods. Pretreatment of seed by nicking the seed coat, or a water or acid soak will speed germination. It is fast growing with reported yields of 3 to 5 m3/ha/yr. On favorable sites it will reach heights of 7 m in 11 years. Interlocked, close grained, sapwood is whitish, and heartwood is purple-brown, dense, with a specific gravity of 0.61 and a calorific value of 5000 kcal/kg.
