This is one of the most distinct species of tbis group, being 

 readily known by its large broad lower leaves, its lax almost 

 weak habit, and its pale colour both when living and in the dried 

 state. The leaves are a sap-green, the sepals sulphur-yelloAv, the 

 petals bright golden. The column is also well marked, the stigma 

 being large and bossy with a deep depression between it and 

 the rostellum. The sepals are thin, the petals thicker but scarcely 

 flesliy as in most of this section. It loves the steep sides of 

 rocky hills or crags which are turned away from the sun-
