73. ORCHIDACE.E. 429 



"general" area only interrogatively, from not being aware 

 of any authority for this species in South Wales; while the 

 occuiTence of it in the adjacent counties of the Severn and 

 North Wales provinces renders its presence in that of 

 South Wales also extremely probable. A second species, 

 G. odoratissima (Rich.), has been supposed to occur in the 

 south of England; but some error may have arisen through 

 the circumstance of G. Conopsea differing much in scent 

 according to soil or humidity. See the remarks on this 

 peculiarity by Mr. Joseph Woods, in the Phytologist, iii. 

 262. My reference to the published suggestion about the 

 occuiTence of G. odoratissima is unfortunately lost. , , :

Native. Ericetal, Sylvestral. These two alleged spe- 

 cies having been usually recorded as one, under the joint 

 name of O. bifolia, only some of the recently published lo- 

 calities can be confidently assigned to either species a])art 

 from the other. Thus, as in many similar instances, their 

 distribution can only be treated in connexion, because 

 founded upon the united records, not of the last very few 

 years, but of the last and present century. H. chlorantha
