 sheaths. Flowers of medium size, numerous, almost sessile on a 

 long spike. Bracts membranous. Sepals, median free, narrow, 

 incurved ; lateral shorter, broader, connate at the base and 

 produced into a very long cylindrical ascending spur. Petals 

 narrow, free. Lip turned upwards, adnate to the base of the 

 column, produced anteriorly into a long narrow channelled 

 process, inclosed in the sepaline spur with apex inflexed and 

 saccate, auriculate with two erect lobes near the column. Column 

 very short ; rostellum erect, broadly membranous, acuminate in 

 the middle, with the deeply-hollowed stigma at the base ; clinan- 

 drium short, membranous-dilated, the margins continuous with 

 the rostellum. Anther erect on the margin of the clinandrium,
