fragrant, April and May ; fr. R. S. It affords the best and 

 most extensively used timber in India ; the goodness of which 

 must depend in a great measure on the resin, (called rat 

 in the northern, and dhoona in the southern provinces) which 

 it contains. (Royle.)

1. Icevis, Buch. (W. and A. o. c.p. 85. — Dipterocarpus turbinatus, 

 Roxb. Corom. 3, t. 213 ;— fl. ind. 2, p. 612.) L. b Tippera, 

 Ava. Fl. large, white, tinged with red. In H. C. G. fl. March ; 

 fr. May and June. Yields an abundance of Wood-oil. A large 

 notch is cut into the trunk of the tree, near the ground, where 

 a fire is kept up, till the wound is charred, soon after which 

 the balsam begins to ooze out : the average produce of the best 

 trees during the season, is said to be sometimes 40 gallons. 

 It is found necessary, every three or four weeks, to cut off the 

 old charred places and burn them again. In large healthy 

 trees, abounding in balsam, they even cut a second notch in some 

 other part of the tree and char it as the first. These opera- 

 tions are performed during the months of November, December, 

 January and February. Should any of the trees appear sickly 

 the following season, one or several years' respite is given them.
