Obs. I have named this genus in honour of Mr. Thomas 

 Hoy, whose merits as an intelligent and successful m 

 cultivator have been long known to the botanists of this 

 countiy. I have added specific characters of the only two 

 species with which I am acquainted; but Hoya carnosa 

 probably includes several species, which can only be deter- 

 mined from living specimens : it is also to be considered as 

 the type of the genus, Hoya viridiflord differing in some 

 degree in the structure of its corona, and considerably in 

 habit.
