The genus Gaylussacia, so named after M. Gay Lussac, 
the eminent French Chemist and Philosopher, differs from 
Vaceinium in the same way as Arctostaphylos from Ar- 
butus—it has but a single seed in each cell. The species 
are chiefly found in Brazil, where they are common, Peru, 
and the North of India, and among them are several which, 
as this species shews, would be worth introducing to cultiva- 
tion. 
G. Pseudovaccinium is stated to be a native of sandy 
open plains in Brazil. Auguste de St. Hilaire says that he 
found it on the coast from the city of Caravellos in the Pro- 
vince of Porto Seguro as far as the island of St. Catharine, 
and that it forms a shrub from one to two and a half feet high. 
At least it is to be presumed that this is the plant he means, 
December, 1844. 2€
