In the Supplement to the ‘ Orchidece of British India ’ I have (vol. vi. 
. 189) corrected the blunder which I had made in the description of 
from overlooking the very obscure true 
petals of this plant, and mistaking for them the broad nerved wings of 
the remarkable column. As there stated, I am indebted to my artist, 
Miss Smith, for pointing these out to me. They are not, as described 
by Reichenbach, triangular-ligulate, but each forms an extremely short 
transparent membrane, not a fourth of the length of the column, to the 
broad base of which they are adnate, and along whose foot they are 
decurrent.—J. D. H.
