The handsome QOdontoglossum here figured is a native 
of Guatemala, originally described as O. platycheilum 
from a solitary plant which had flowered in March, 1892, 
in the collection of Mr. R. I. Measures of Camberwell. 
The county of origin of that example was then unknown ; 
all that was known regarding it was that it had been 
acquired along with some other orchids when the 
Downside collection was dispersed. More than a decade 
later a specimen of the same species were received at 
Kew in a collection of dried plants communicated by 
Mr. J. Donnell Smith. This specimen had been gathered 
by Heyde and Lux in April, 1892, at an elevation of 
8,800 feet, at Chiul in the department of Quiche, 
Guatemala; it is now known that a fruiting specimen 
collected by Bernoulli in Guatemala in May, 1860, belongs 
to the same species. In 1905 Messrs. Sander and 
Sons, St. Albans, were able to make an importation of 
this Odontoglossum, which since then has flowered fre-
