It is a very slow growing tree. It obtains a height from 20 to 30 feet. It occurs more or less gregariously in dry hills up to 4,000 feet. It is found in various geological formations and is capable of growing in poor dry shallow soil where few other species can survive. It may occur pure or in mixture with other trees. It is not found in loamy soil but has been introduced. (3). In West Pakistan it is mainly found in Attock, Jhelum and Rawalpindi Forest Divisions. It is also found in small quantity in Baluchistan, Sind and Hazara (N. W. F. P.).
It is used as fuel wood, for agricultural implements and for hedge purposes. In some places the wood is also used for building small houses. Phulai Gum locally known as
