Native. Sylvestral. The plants intended by authors 

 under the three first of the above four names, are not 

 known to me as distinct or clearly distinguished species ; 

 and I find it impossible to apply many of the recorded lo- 

 calities rightly to the different forms. They are, therefore, 

 unavoidably treated in the aggregate at present. I sup- 

 pose Mr. Babington correct in separating the E. ovalis as 

 a distinct species ; and could wish that I was equally able 

 to separate correctly its special localities from those of 

 " E. latifolia," usually so designated, and even from those 

 of "E. rubra," to which latter plant the localities of E. 

 ovalis have been occasionally assigned. The neighbour- 

 hood of Settle, in the West of Yorkshire, has become 

 familiar to English botanists, as the chief locality of E. 

 ovalis, by the numerous specimens so liberally distributed 

 by Mr. Tathara. In 1832, I gathered Epipactis latifolia, 

 as I then deemed it, on limestone rocks, by Loch Errboll, 

 in Sutherland ; but the specimen in my herbarium appears
