Tlie basal sheaths are almost colourless, striate, and blunt, 

 reaching f in. in length. The leaves (to 2 in. in length by 2 lines 

 in breadth) become narrowed at the base and apex. The peduncle 

 bears a colourless scarious lanceolate-acummate bract in its lower 

 half ; the upper ilower-bearing portion is zigzagged ; the reddish 

 pubescence is continued up the pedicels on to tue outside of the 

 sepals. The scarious bracts are scarcely 1^ lines long, the ovary 

 and stalk 2 lines. The sepals are 3 lines long, the dorsal is scarcely 

 1 line broad, the lateral 1^ at the base. Tlie petals are 2^ lines 

 long by less than i line. The upper part of the lip, above the claw, 

 is 2^ lines long by 2 lines at the base ; the central lobe is just over 



1 line. The column is 1 line long.
