 petals ochroleucous, spreading ; the former oblong, obtuse; the 

 latter similar to them, but shorter and broader. Spur short, 

 very obtuse. Lip projecting, about equal in length to the petals, 

 unguiculate, clawed (a white callous disk on the claw), three- 

 lobed, the side-lobes short, rounded, incurved with a deep blood- 

 coloured spot at the base ; the middle lobe very large, subrhom- 

 boid, acute, the whole slightly sprinkled with hairs, deep-orange, 

 with a white margin and apex ; column short, but very decurrent, 

 white, variously spotted in front with green and purple. Anther-
