Pseudobulbs tufted, flattened, 3-7 in. long, covered when young with 

 large loose sheaths. Leaves four to six, subcoriaceous, 4-7 in. long,,

 peduncle about 1 in. long, stout, naked below. Flowers many, 

 white tinged with yellow, densely crowded, subglobose, about J in. 

 across, inodorous ; floral bracts equalling the sessile pubescent ovary,

 pair deeply concave. Petals oblanceolate-oblong, spreading, nearly

Rhizome stout, clothed with imbricating tubular sheaths. Pseudobulbs

 tapering to the base, subcoriaceous. Scapes from the base of the 

 pseudobulbs, about as long as the leaves, clothed with dense pale 

 tomentum and with many sheaths at the base. Flowers distant,, 

 yellow, J in. across, densely white-woolly outside ; floral bracts lanceo- 

 late, pilose, shorter than the pinkish piloFe stalked ovary, shrivelling 

 as the flowers open. Dorsal sepal small, lanceolate; lateral pair
