GUM ELEMI. GUMBO LIMBO. WEST-INDIAN BIRCH.

 through the West Indies. 



A tree often 18 meters in height, with a trunk 0.50 to 0.70 meter in diameter ; one of the largest and most 

 common trees of southern Florida, of very rapid growth and decay. 



Wood very light, exceedingly soft and weak, spongy, containing many scattered open ducts ; medullary 

 rays numerous, thin ; color, light brown or gray, quickly discoloring with decay ; specific gravity, 0.3003 ; ash, 

 2.04; used in making live-fences, pieces of the trunk when planted in the coral rock of the keys throwing out roots 

 and growing rapidly. 



The aromatic resin obtained from this species was formerly somewhat used in various forms, under the name of 

 Caranna, as a remedy for gout ( Watts. Chem. Diet, i, 14Q.-ttuibourt, Hist. Drogues, 1 ed. iii, 525, f. 749) ; and in the 

 West Indies is manufactured into a valuable varnish. An infusion of the leaves is occasionally used as a domestic 

 .substitute for tea.
