Although the specimens do not absolutely agree, especially with reference to the 
calyx, with the original description of Duchassaing and Walpers, I do not hesitate 
to identify them with their Vitex floridula. This is the species of common occurrence 
in the district explored by Duchassaing and the only one known which has close 
affinities with V. divaricata Swartz.
