The first notice I received of the existence of this pretty 
epiphyte was from Mr. Bateman, who favoured me with a 
specimen in February last. It was afterwards sent from 
Chatsworth. It is a native of Guatemala. 
The more striking features in it are the long thin pseudo- 
bulbs, the very narrow grassy leaves, and the singular protu- 
berance at the base of the white lip. This protuberance is 
deep yellow spotted with crimson, very fleshy, firm and shining, 
and is almost horseshoe-shaped in front, while it is distinctly 
three-lobed behind, in consequence of two deep depressions. 
Fig. 1. shows this structure; 2.is the pollen-masses with a 
part of one of the masses cut off. 
It is now well known that many Orchidaceous plants*from 
Mexico and Guatemala require less heat than is generally 
kept in our moist stoves, and to many of them it is particularly 
injurious if applied at those seasons when the plants are in a 
resting state. This is a plant belonging to this class, and 
therefore there is nothing worse for it than over-excitement 
caused by the application of a high temperature and moisture
