Very variable if, as I think probable, the following forms are correctly referred 

 to it. The perianth alone is exposed from the broad sheathing scarious bract as in 

 0. ensiformis and others. The rachis is stout or slender, the capsule sessile. There, 

 is such a mixture of specimens in a very bad state under Wallich No. 1948 that a 

 reference to them is of no use.

Whole plant 2 in. high. Leaves about .J in. broad, straight. Scape adnate at 

 the base to the uppermost leaf, rachis filiform ; flowers red, about - in. I have seen 

 only one specimen of this little species, which is most nearly allied to O. Griffithiana, 

 Lindl.

 terete sparsely bracteate, spike decurved, flowers minute subsessile densely 

 imbricate, bracts short erose, petals oblong, lip very short 3-lobed, lateral
