Sent in January 1851 from the collection of Messrs. Lucombe 
and Pince, of the Exotic Nursery, Exeter. By them it was pur- 
chased at one of Mr. Stevens’s sales of Columbian Orchidee, in 
1850, where it was entered in the catalogue as the “ Red Bull’s- 
mouth.” 
We were at first disposed to consider it a distinct species from 
C. aurea, levis, or bractescens, but a further investigation led to 
the conclusion that it was rather a highly coloured variety of 
C. aurea, to which, indeed, C. bractescens is very nearly allied, 
nor do I find the chief distinction which Dr. Lindley lays stress 
upon, available; viz. that on the labellum of C. aurea there are 
five principal ridges, and three minor ones on each side, all 
downy and diverging, “while in C. dractescens there are five 
equal ridges all smooth and parallel.” In our drawing of C. 
bractescens, now before us, the five ridges are all downy in their 
lower half, while in C. aurea, both a and 8, the three lesser
