rery prominent on a longitudinal Mrtion. Medullary rays fine. The 

 dillWence in structure between A. Lebbek and the woods of A. proccra is 

 very slight. 



Sub-Himalayan tract from the Jumna eastwards, Bengal, Satpura Range in the 

 Central Provinces, Cu/.eral, South India and Burma. 



( Irowth very rapid. lirandis says that it attains in 12 years 3 to 4 feet, and in 



',]() years 4 to 6 feet girth. This would give about 2 rings per inch of radius, which 



rv rapid. Our specimens are of somewhat slower growth, 6 rings per inch. 



Weight, according to Skinner, No. 3, 39 Ibs. ; Brand is, No. 2S, -IS 11 is. ;our specimens 



givr an average of 40 Ibs. Skinner gives P = 884 ; Brandis 750. The wood is straight 



and even-grained, seasons well, and the heart wood is durable. It is used for sugarcan- 



crushers, rice-pounders, wheels, agricultural implements, bridges and house posts. Ifc 



is used by tea planters for stakes for laying out tea pmlens, as it is found to split well, 



and occasionally for tea boxes and for charcoal, for which it is found to be very good. 



It gives a copious gum.
