This ppecies is intermediate between OdohtocJiilns and Ancedocli'dits, 

 having tbe small sac lamellate witbin and more or less covered by 

 the sepals of tbe former genus, but the sepals contraeted at the base 

 and liot forming a mentum, and the spurless lip of the latter. It 

 appears to me that these two genera might well be combined, perhaps 

 together with Cheiroshjlis, which only differs in tbe cohesion of the 

 sepals into a tube, and the appendages of tbe column ; but if so, Zevxihe 

 must follow. These and all tbe other Sfiravthecp of India want a very 

 careful analysis of living specimens; so long as the position of the 

 stio-ma is unknown in so many, and the true nature of appendages 

 ot'the column in all, tbe limitation of the genera must be uncertain. 

 I once hoped that tbe very remarkable differences in the structure of 

 the pollinia would afford a% ailable generic characters, but was obliged 

 to abandon this hope. The analyses of the orchids figured in these 

 * Icones,' and those described in the pages of the * Flora of British India, 

 have been a work of great labour, executed first by myself at various 

 periods between 1882 and 1892 ; and those of the ' Icones have been 

 more recently, and quite independently, revised by my accomplished 

 artist. Miss Smith, who has portrayed the results of our analyses, 

 together with the drawings of the plants themselves.— J. D. H.
