Descr. There is no evident stem, no pseudo-bulb. Roots 
consisting of numerous thick, whitish, fleshy fibres, from 
the top of which springs the solitary leaf almost a foot long, 
singularly thick and coriaceous, keeled on the middle at 
the back, the point a little reflexed and acute : the base has 
three or four imbricated scales, of which the outer one is 
withered and membranaceous, the rest green and herba- 
ceous. From the base of this leaf, and from within one of the 
scales just mentioned, arises the peduncle, as thick as a 
goose-quill, bracteated, two feet and more long, terminated 
_ by a large, many-flowered panicle. Pedicel, including the 
cylindrical ovary, an inch and a half long. Flowers an inch 
across, the whole perianth waved. Sepals free to the base, 
broadly obovato-spathulate, greenish-yellow spotted with 
red-purple, concave : the petals similar to them in form and 
colour, but rather narrower. Lup yellow, deeply divided into 
three lobes, the lateral lobes obovate, the middle one trans- 
verse, broadly oblong, tapering at the base, the apex notched: 
the disk of the labellum at the base is considerably elevat- _ 
ed, spotted with orange, and bears four tubercles placed in 
a cross-shaped manner, and between them a larger and 
more prominent one. Column short, having on each side, © 
near the top, a curved wing or horn-like process pointing 
downwards. Anther-case very large.
