 synonym of Marcg. Fruit ovate, 4-celled, resembling that of 

 the laurel, with the nut involved in a brittle covering, containing 

 4 stones or 4 cells wrapped up in viscid pulp, which has a bal- 

 samic smell and taste, hardens into a grey resin, and is used to 

 burn as a perfume. The whole tree is very sweet-scented, and 

 pours out a very odorous clear balsam from the wounded trunk

 where it is called Chlpa. Amyris decandra, Willd. spec. 2. p. 

 335. I. pentandra, Aubl. guian. 1. t. 135. When the bark of 

 this tree is wounded, a whitish liquid flows out, which has 

 the scent of citrons, when dry becoming a yellow transparent 

 resin, which is found in small pieces under the bark. This resin 

 is carried by the Caribbees to Cayenne, where it is employed in 

 churches as incense.

 altissima, Willd. spec. 2. p. 336. There are two varieties of 

 this tree, the one called Cedre blanc the other Cedre rouge. 



The wood of the Ccdrc rouge is considered more durable than 

 the Cedre blanc for household furniture and for carpentering, 

 and canoes and boats made with it last longer than those made 

 with the other kind.
