Descr. Pseudo-bulbs ovate, compressed, obscurely fur- 

 rowed near the margin, more or less sheathed with large 

 brown scales at the base, and bearing a single, oblong, 

 obtuse, thick, coriaceous leaf at the extremity. From the 

 base of this leaf the peduncle arises, a span to nearly a foot 

 high, slender, articulated and sheathed at the articulations, 

 five- or six-flowered at the top. Flowers rather small, deli- 

 cate lilac-rose colour, with a deep purple eye in the centre 

 of the lip. Sepals spreading, equal, lanceolate. Petals resem- 

 bling them, but larger and broader. Lip standing forward, 

 lilac, about equal in length with the sepals and petals, 

 oblong, three-lobed, tapering at the base, with the sides 

 there inflected, so as to embrace the column : the lateral 

 lobes acute, spreading ; the middle lobe ovate, oblong, 

 obtuse, even retuse at the apex, waved and striated : the 

 disk towards the base is marked with an elevated and stri- 

 ated, broad line, and the colour is deep purple. Column 

 rather short, semicylindrical, dark red purple, especially in 

 front. Anther-case hemispherical.
