This genus was first proposed by P. Browne in 1756 for a Jamaica plant, and was so 
named because its follicular fruit assumed the form of a viper (iyw). At that early 
period no precise genus was known, and species were defined in two or thieo words. 
Though Browne gave ample details of his species, Jacquin was the first to give a regular 
diagnosis of the genus Xchites. Linnæus in 1764 acknowledged Echites under very 
similar circumstances ; so that his definition of the genus is of little value. This example
