E. media, Fries. Bab. 323. Woods, common : Dane Garden Wood ; etc. 

 Note. — 1 may mention the following among the marks which serve to distinguish 



these closely alhed species. E. media is a taller plant than E. latifolia, and is altogether 



lighter in colour ; the lip, which in E. latifolia is usually purplish, is in E. media 



almost colourless ; in E. media it is longer than broad, terminating in a sharp point, 



Avhile in E. latifolia the point is blunt, and usually curves under. The blossoms of E. 



media are usually larger than those of E. latifolia, and the spike is denser. E. media 



commences to blossom about ten days earlier than its relative. 



^ E. purpurata, Sm. 1 " There is an ExApactis growing in the Stoken- 

 church woods, which is, in its young state, quite purple in both leaves 

 and stem j it must I suppose, be E. purpurata ; I have seen it also in 

 Bisham Wood, but have not had an opportunity of seeing it in flower." 

 Phyt. i. 993, O.S. I have received a specimen gathered near Hampden, 

 to which the preceding description well applies ; but I was equally un- 

 fortunate in obtaining it in blossom.
