We have had this drawing in our portfolio since April, 
1844, when a specimen was communicated by S. Rucker, 
Esq. Itis no doubt a pale variety of G. bufonia, of the 
original spotted form of which afigure will be found at fol. 2 
of our volume for 1841. 
The cultivation of this genus has become so generally 
understood, and its grotesque forms so familiar, that we 
believe the most acceptable service we can now render our 
readers, is to point out in what way the numerous varieties 
may be reduced to their species. With this view the fol- 
lowing memoranda have been prepared :— 
The best marks of distinction reside in the form of the 
little horns which stand right and left of the base of the lip. 
These are long and enlarged at their end, in some species ; 
small, and resembling a mere callosity, in others; and 
missing in another. Attention to them will render further 
differences more intelligible. 
I. Horns of the base of the lip long, and enlarged at the point. 
1. G. atropurpurea. In this, which is now one of the com- 
monest species, in addition to the deep claret purple of 
the flowers, the base of the lip is very much narrowed, 
and the lateral horns are as long as its stalk ; hence it
