 An evergreen tree of variable size. Mostly confined 

 to the dry and snbalpine forests of Mysore and 

 Coorg. Leaves in whorls of 4— 7, petiolate, elliptic- 

 oblong, coriaceous, white underneath ; average blade 

 7x2 in. Follicles 1 — 2 feet, in pendulous clusters, 

 very slender. The wood of this tree is of little 

 value, being soft and light — weight 28 lb. per cubic 

 foot. — but the bark and leaves are prized for their 

 medicinal properties. The bark, which is astringent, 

 antiperiodic,axid anthelmintic, is known commercially 

 as dita harJc. It is not, however, an article of Indian 

 commerce. The specific name scholaris has originated 

 from the frequent use of the wood in Indian 

 schools both as blackboards and sandplanks, on 

 which native children trace their letters. 



CvQtivation. — Easily raised from seed and per- 

 fectly hardy in the drier forests of Mysore, where it 

 is also self -productive.
