I stated in Fl. Brit. Ind. that this little plant should probably form 

 a separate genus from Ccvlogytie, for which 1 proposed the name 

 Adrorhizon^ in allusion to its curious thick roots; but that I awaited more 

 specimens before establishing it. These I have (in the Peradeniya 

 Herb.) now examined, and they confirm my opinion of its proving a 

 very distinct genus, which is nearer to the Himalayan Pafiisea, Lindl. 

 (see Ann. Bot. (kird. Calcutt. v. t. 29) than to any other, differing in the 

 absence of the long sigmoid claw of the lip of that genus.
