 D. C. legum. mem. xii. t. 26. f. 120. germ. Jacq. amer. pict. 

 p. 63. t. 264. f. 65. Flowers of panicle pedicellate. Petals 

 yellow, striped with purple. Stamens purple. The filamentose 

 white substance contained in the pods is as sweet as honey, and 

 is eaten by the Indians with great avidity. It is purgative when 

 fresh gathered, but loses this quality as it grows old. Between 

 the principal roots of the tree exudes a fine transparent resin, 

 white, yellowish or red, which is collected in large lumps, and is 

 called gum-anime. It makes the finest varnish that is known, 

 superior even to the Chinese lac ; for this latter use it is dis- 

 solved in the highest rectified spirits of wine It burns readily, 

 and with a clear flame, emitting a grateful and fragrant smell, 

 for which reason it is sometimes ordered by way of fumigation 

 in the chambers of persons labouring with asthmas or suffbcative 

 catarrhs. Its vapours not only strengthen the head, but all 

 parts of the body affected with cold. Some apply it outwardly, 

 dissolved in oil or spirits of wine, to strengthen the nerves. An 

 oil may be distilled from it, useful in palsies, in cramps, and con- 



tractions of the sinews. The solution in spirits has been thought 

 not inferior to guiacum in venereal cases. The inner bark is an 

 excellent vermifuge in spirit or decoction. The wild bees are 

 fond of building their nests in this tree. The timber of old trees 

 is reckoned excellent, and is in great request for wheel-work in 

 sugar-mills, particularly for cogs to the wheels, being extremely 

 hard and tough ; it is so heavy that a cubic foot weighs a hundred 

 pounds ; it also takes a fine polish. Courbaril is the name of 

 the tree in some parts of South America.
