Colombia. Fine specimens, and live plants brought 



home by Mr. Hartweg shew this to be a rival of C. labiata. 

 Its flowers are as large, and are described as being of a 

 beautiful dark pink.

 (C. MossicB, Hooker in Bot. Mag. t. 3669. Bot. Reg. 



1840, t. 58.) a Brazil. /3 La Guayra One of 



the most noble species of this fine genus. The varieties 

 of what has been called C. Mossise are numerous, and 

 seem to prove that no reliance can be placed on the 

 supposed distinctions between it and C. labiata. It must 

 however be confessed that the question is open to further 

 consideration.
