Type collected by George Samuel Jenman (No. 6921) at 

 Berbice, British Guiana, in January, 1896, and deposited in the 

 herbarium of the New York Botanical Garden. The species is 

 closely related to the Jamaican Vitex umbrosa Sw., which is 

 endemic to that island. Indeed, it has hitherto been invariably 

 confused with this species. The fact that the South American 

 specimens, uniformly labeled "Vitex umbrosa Sw." in all her- 

 baria and even cited thus by Schauer, are not conspecific with 

 the Jamaican plant, was first discovered by Dr. Nathaniel Lord
