to three or four from the summit of the young pseudobulb, oblong- 

 lanceolate, slightly twisted, subcoriaceous. Scape radical, about 

 a span long, braeteated, with four to six lanceolate, sheathing 

 scales. Ovary pedunculiform, one inch and a half long. The 

 spread of the flower is considerable, but the floral coverings are 

 narrow. Sepals much divaricated, linear or linear-oblong, yel- 

 low-green, indistinctly speckled with red ; petals conform with 

 them, but erect and nearly parallel with the upper sepal, slightly 

 incurved. Lip large, broad-oblong, tapering below into a long 

 claw, three-lobed ; side-lobes rounded, erect, purple within ; 

 middle lobe broad-oblong, quite white, barred transversely with 

 short streaks of dark purple : there are a few elevated callous 

 lines at its base. Column much elongated, clavate, incurved. 

 Pollen-masses two, transverse, each two-lobed, and attached to 

 a large triangular gland.
