As early as the year 1696 this species was introduced 

 into the annals of Botany by Sloane in his Catalogue, and 

 shortly after, in the year 1707, he described it accurately 

 in his Natural History of Jamaica. Patrick Browne also 

 gave a good description of it in Civil and Natural History of 

 Jamaica, p. 313. 



I have shown while discussing the name V. arborescens 

 (L. ) Sw. how Swartz came to apply this name to the Jamaican 

 plant. In the same passage I have mentioned the reasons 

 for applying the name V. arborescens to the Martini que plant. 

 Then there arises a problem: what is to be the correct name 

 of the Jamaican plant, the previous V . arborescens. At first 

 I thought it must be V . intonsa Gleason, this species agreeing 

 perfectly with the type specimen of V. arborescens Sw. How- 

 ever, when I realized that V. arborescens sensu Swartzii, 

 V. intonsa Gleason, V. permollis Gleason, V. albicoma 

 Gleason and even V. divaricata Sw. all were only forms of 

 one species, I merely had to take V. divaricata Sw. for its name. 

 With this the problem of the synonymy of this Jamaican 

 species had been definitively solved. 



It is hardly necessary to state that V. divaricata as 

 here understood is an extremely variable species. Gleason, 

 having abundant, new-collected material of it at his disposal, 

 described some of its forms as new species, viz. V. permollis, 

 V. intonsa, V. albicoma, and V. amaranthina. Of these V. 

 intonsa is exactly the same as the type of V. arborescens Sw., 

 V. permollis is an extraordinarily densely pubescent form, 

 and V . albicoma a nearly glabrous one. I have not perfectly 

 satisfied mvself about the taxonomic value of V. albicoma.
