I know of no Habenarioid genus in which this curious little plant 

 could be placed. The structure of the lip is very curious. The more 

 or less broad lanceolate concave half next the column has the margin 

 nvolute for the other half, forming a solid body, which appears to be 

 n some specimens grooved above. The spur Mr. Clarke describes 

 n his notes as transparent and glossy. The two slender spurs « I 

 the column, one on each side of the anther, and as long as it is, are 

 very curious. — J. D. Hooker.
