A medium- si zed evergreen tree with dark-brown bark. Branchlets finely,

 the older branches. Leaves 1-2 in. long ; rachis downy, with several 

 glands ; pinnce 3-6 pairs, -^-1^ in. long; Leaflets 10-20 pairs, ^-j in. long, 

 membranous, glabrous or downy. Peduncles short, 4-6'-nate, densely 

 grey-downy, with bracts above the middle. Heads I in. in diam. Flowers 

 yellow, fragrant. Calyx minute, campanulate. Corolla twice the calyx, 

 Fods usually solitary, 3-6 in. long, distinctly stalked, rather fleshy ;; 

 sutures deeply indented between the seeds, subindehiscent, densely and 

 persistently grey-downy. Seeds 8-12, in a single row. 



Common within the area, but only as a planted tree or self-sown, 

 DiSTEiB. Throughout the greater part of India and in Ceylon, but 

 nearly always planted. According to Brandis the tree is probably 

 indigenous in Sind, and perhaps in the N. Deccan. It is found also in 

 Arabia, Egypt and in Trop. Africa. It flowers during the rains, and 

 the pods ripen in the cold season. The young pods and foliage are 

 greedily eaten by all kinds of cattle, as well as by camels ; and 

 as such fodder is of immense value during seasons of drought, every 

 encouragement should be given towards extending the growth of this 

 tree in such lands where agricultural crops cannot be grown with 

 profit. For a full account of the many useful products yielded by this 

 valuable tree, far too numerous to be mentioned here. Dr. Watt's- 

 Dictionary article should be consulted.
