Vachellia leucophloea (Hindi: रेवंजा), also called reonja, is a moderate sized tree found in southern India. It is sometimes mistaken for Prosopis cineraria with spreading crown and somewhat malformed and crooked trunk. It attains a height of about 20 to 30 ft and a girth of 2 to 3 ft. New leaves appear in April, and yellowish white flowers appear from August to October. The pods ripe by April and the seeds germinate readily if moisture is available. The tree is very hardy and stands drought well. It is frost hardy except in young age. It coppices well and produces good root suckers. It suffers from goat browsing particularly in early stage. Fruits are thin, flat, curved tomentose pods (difference from Prosopis cineraria).
