Lindley describes the lip as villose inside, and this character is repeated in the 
Botanical Magazine, yet the plate itself shows that this is erroneous, as I also find in 
examining several flowers from Barter’s specimens. This plate was prepared from 
plants sent to Kew by Mr. Gustav Mann from the same locality, but no dried 
specimen appears to have been preserved.
