 contracted into a claw, the lobes lanceolate and produced into long fine points- 

 embracing the galea. Labellum oblong-linear, tapering to a point. Column 

 with a short basal projection, lower lobe of the wings broad and obtuse, upper

 Leaves in a radical rosette, petiolate, ovate or elliptical, | to ^in. long. Scape 

 1-flowered, 6in. to 1ft. high, usually with a single long loosely sheathing empty 

 bract besides the one under the terminal pedicel. Galea nearly lin. long, much 

 curved near the base and again towards the end, so as to give the flower a. 

 nodding appearance, obtuse or acuminate in front ; lower lip shortly and broadly 

 cuneate, the lobes long and lanceolate, tapering into long points embracing the 

 galea. Labellum oblong-linear, obtuse, 4 to 5 lines long, the surface smooth but 

 sometimes minutely ciliate, the basal appendage narrow-linear, curved, peni-
