The middle sepal (a) has coalesced with the left (h) as much 

 as ? from the base, the third sepal free. Of the lateral petals 

 we find the right one ((/) only, the left being absent ; also the la- 

 bellum is present although at one side only overlapping the 

 gynostemium, as the left margin is bent inwards in front of 

 the column. The latter itself is inclining towards the left half 

 of the flower. Also the top of the column, together with the 

 rostellum and the anther are slanting. The right anther-cell is 

 normal, but the left cell a little bigger, bearing a petaloid 

 little lobe.

At the base of two successive pseudo-bulbs there developed 

 a short, few segmented lateral shoot with roots terminating in 

 a small leafless pseudo-bulb. This pseudo-bulb produced at its 

 top a very short inflorescence with a few flowers. The latter 

 were normal. (Fig. 36).

1°. In one flower, for the rest normal, the lateral sepals have 

 grown together to a concave whole under the labellum. 



2°. The labellum of the flower, for the rest normal, has the 

 shape of an ordinary petal and is besides unmoveable. Compared 

 with the other petals it is slightly shorter and bears on the 

 upper surface an irregular longitudinal ridge corresponding on 

 the opposite surface with a corkline. The gynostemium is not 

 quite normal, showing the shape of a square prism instead ot 

 an arched upper face. Moreover there are no stigmas, the top
