This genus is allied to Irlbachia of Martius, and Leianthus 
of Grisebach, but differs essentially from both in the shape of 
its corolla, and sessile anthers. Var. a. has the stigma of Irl- 
bachia, while B. has that of some of the species of Leianthus. 
Both of the varieties grow together, and are equally abundant. 
I was at first inclined to consider them two distinct species, but 
with the exception of the very short style and umbraculiform 
stigma of var. 6, there is nothing to distinguish them. 
This remarkable difference in the form of the stigma is most 
probably caused by the depauperation of the style. I have 
named the genus in honour of my friend G. C. Hockin, Esq., 
of Rio de Janeiro, who accompanied me on my last journey 
to the summit of the Organ Mountains, and to whom I am 
deeply indebted for much kindness during my wanderings in 
Brazil. It will also serve to commemorate the name of his 
brother, John Hockin, Esq., of Dominica, who is devoting 
much attention to the botany ofthat Island.
