Pascual. This species is found in short uncultivated grass 

 pastures, especially on the coast of Scotland, but it occurs also far 

 inland, ascending over 1000 ft. 



See remarks under E. brevipila as to the borders of the areas of 

 this and E. borealis meeting in the British Isles. 



Since this Monograph was completed Prof. Wettstein has 

 written to me respecting the varied forms of E. borealis and E. 

 brevipila of which I communicated a series of specimens. I had 

 doubts whether many glabrous forms which have been referred to 

 E. borealis should not be looked upon as glabrous forms of E. brevi- 

 pila, or that there are glandular forms of E. borealis and that we 

 have only one species, which was originally my opinion some years 

 ago. Prof. Wettstein writes that he has never as yet seen an 

 eglandular form of E. brevijiila and this fact mainly disposes him to 

 believe that we have two species and that hybrids occur between 

 them. For the present I assume that Professor Wettstein is 

 correct and that we have two distinct species, and that hybrids do 

 occur between them, but I am convinced that forms which have 

 been referred to E. borealis do represent an eylandular form of E. 

 brevipila, which is not unfrequent in Scotland. Future observation 

 may possibly determine that E. borealis is an eglandular form of 

 E. brevipila which has a separate area, and a more northern exten- 

 sion than the parent form, and that this eglandular form is con- 

 stant within this area except on its southern border.
