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.
