margins of the convolute side lobes recurved, crisply cre- 

 nate, as is the orbicular mid lobe, spur \ in. long, horn-like, 

 strongly incurved or involute, acuminate; fr. 2 in. long, 

 clavately fusiform. 



Open pastures in montane zone 3-7000 ft.; rather common, especially 

 at the higher elevations. Fl. Sept.-Nov., April, June ; rather variable in 

 colour ; sep. and petals pale purplish-orange above, and greenish-yellow 

 on back, but sometimes whole fl. pale orange-yellow, the lip a pale 

 uniform orange-yellow; or lip white, more or less suffused with pink, or 

 all red-violet. The colours in Lindley's fine plate are too vivid. 



Endemic. It is remarkable that so conspicuous a plant should have 

 no recorded native name.
