The genus Catuistacnys has been established by M. 
VenreNAT, in the second volume of the Jardin de Malmaison, 
where he has given a full description and figure of one 
species, under the name of lanceolata, and has slightly 
mentioned a second, which he presumed to belong to the 
same genus; but, as it had not at that time flowered, its 
place could not be positively ascertained. This last has been 
since referred by Mr. Brown, in the Hortus Kewensis, to 
OxyLopium, a genus to which Ca.uistacnys seems very 
nearly allied; but our plant is doubtless a congener of 
Ventenat’s Cauuistacnys lanceolata, and is totally different 
from Gompnotosium ellipticum of LapitLarDIERE; it was 
received from Paris, by Messrs. Loppigzs and Sons, at the 
same time with the latter, under the name which we have 
adopted. Ventenat’s account of his Caxuisracuys elliptica
