SCHOMBURGK S GUIANA PLANTS. 213 



near Posogueria and Randia, having something of the habit 

 of the latter, but the calyx and corolla are of so peculiar a 

 form, that I am induced to consider it as distinct. The 

 structure of the ovary leaves no doubt as to its being rightly 

 placed amongst Gardeniece.

 Guiana, Schomhurgk. — There are two single specimens from 

 different localities; in the one the corolla is about five inches 

 long, in the other it is more slender and scarcely four inches 

 long; in the latter the leaves are also smaller. In both they are 

 thick and shining with the lateral veins scarcely prominent.

 Posoqueria. His n. 2197 from Piauhy is Tocoyena hirsuta, 

 Moric, and his n. 1043 from Pernambuco, and 1337 from 

 Alagoas are also specimens of Tocoyena^ a genus which I do 

 not find among Schomburgk's.
