and spreading, wider and toothed on the upper margin towards 

 the base, margins incurved, 1*6-1'8 cm. long ; odd sepal similar 

 but shorter and recurved, with a horizontal or ascending com- 

 pressed retuse spur, about f of the length of the limb ; petals 

 with an erect earlike lobe in front, knee-bent behind, then 

 falcate-linear recurved and bifid at the apex ; lip somewhat 

 fiddle-shaped, the lower part (hypochilium) ascending ovate 

 inflated-concave, the middle (mesochilium) sharply deflexed, 

 ovate, margins inflexed erosulate, somewhat fleshy, with minute 

 papillffi scattered on its surface, suddenly contracting into the 

 upper part (epichilium) which is filiform, beak-like, minutely 

 channelled in front, 4-8 mill. long. 



Described from numerous living and dried specimens. Colour 

 of the flowers varying from pale lilac to rose-red, with minute 

 greenish spots on the surface of the mesochilium of the lip, and 

 larger pale purple spots on the petals. This seems to be a vari- 

 able plant in the length and degree of curvature of the sepals, by 

 both which characters it is well distinguished from all its con- 

 geners, except perhaps D. longipetala {Schizodium lojigipetalum, 

 Lindley), which, however, is probably a mere variety of our 

 present plant, characterised by slight differences in the petals.
