and Bonpland in the temperate parts of Mexico, near El 
Puerto de Andaracuas, between the towns of Guanaxato and 
Valladolid de Mechoacan, on mountains, at the elevation of

flowers than I have yet seen in our garden specimens. 
Mr. Skinner again found it in Guatemala, and sent it to 
Mr. Bateman, who published the first figure from living 
plants in his magnificent work on the Orchidacee of Mexico 
and Guatemala, t. 4.

impaired when they are tied up to a stake, and so forced into 
a position alien to their habits. They have an agreeable 
odour, which Mr. Bateman compares with justice to new hay. 
In this species we have another instance to add to those

flowers in a genus so very generally yellow. In the coloured
