 or notched at the apex, wedge-shaped at the base, narrowed to the short, broad 

 leaf-stalk, entire on the margin, yellowish green, smooth and shining above, paler, 

 smooth and finely veined beneath. The flowers are few, clustered in cymes; 

 calyx of 8 to 16 imbricated sepals, which are thick, leather-Uke, and suborbicular; 

 the corolla has 4 broad obovate petals 2.5 to 3 cm. long, leathery, yellow, some- 

 times slightly unequal; stamens short and thick, several to many in the staminate

The gummy exudation is used in the West Indies as a dressing for wounds, 

 and the bites of insects. 



No species of the genus is known to inhabit Florida at the present time, but 

 there is evidence that another one, perhaps Clusia rosea Linnasus, formerly existed 

 on Pine Key and Key West; further exploration of the Keys may still reveal one 

 or the other. 



The genus is composed of about 80 species, confined to tropical and subtropical 

 America. The name is in commemoration of Charles de I'Ecluse, a French bota- 

 nist of the sixteenth century. The type species is Clusia major Linnaeus, of the 

 West Indies.
