ORCHIDACE.E 



The flowers suggest those of Sarcockilus Teysmannii J. J. 

 Smith in the general form of the labellum. The inflorescence is 

 branched with the branches branched again. Flowers and fruits 

 are present at the same time. The first branch springs forth about 

 4 cm. above the leaves. The branches in dried specimens are con- 

 spicuously two-winged. The claw of the labellum forms a wide 

 canal, with erect sides, which leads into the saccate termination ; 

 the lateral lobes rise perpendicularly above the very small, some- 

 what thickened middle lobe, with their acute tips pointing out- 

 ward from the column. Seen from the side the sac and lobes 

 suggest the head of a horse with erect ears.

 much smaller flowers.
