Prosopis cineraria (L.) Druce
- Family: Leguminosae - Mimosoideae
Synonyms
- Prosopis spicigera L.
Distribution
Occurring naturally from Saudi Arabia to India, cultivated in many semi-arid tropical countries. In South-East Asia it is grown in Java.
Uses
P. cineraria is grown for fuelwood for cooking and heating and provides excellent charcoal with an energy value of about 25 000 kJ/kg. Farmers in northern India often plant annual crops beneath it to make use of the higher soil fertility and to protect the crop against extreme weather conditions. It is used to reforest denuded areas such as sand dunes.
Observations
- Shrub or small tree with an open crown, up to 6.5 m tall with scattered internodal prickles, but without stipular thorns.
- Leaves bipinnate with 1-3 pairs of pinnae; leaflets 7-14 pairs, 4-15 mm × 2-4.5 mm.
- Inflorescence a raceme, 5-10 cm long, often combined into paniculate aggregates.
- Petals yellow.
- Pod slender, elongated, subcylindrical, 8-19 cm × 4-7 mm, constricted between the seeds.
- Seed ovoid, about 6 mm long.
P. cineraria grows in regions with 75-850 mm annual rainfall and a long dry season. It withstands high temperatures (up to 50 °C) and light frost (up to -6 °C) and tolerates alkaline and slightly saline soils. It may become a noxious weed in more humid areas.
