be neglected. The gathering was not mixed ; there was no 

 true segregate E. la ti folia, and most decidedly no atrorubens, 

 and the specimens were as well prepared for accurate deter- 

 mination as the species allows, though that is not saying very 

 much. Mr Cryer's note is correct in saying that there were 

 " intermediates," but that was only saying agaifl what Mr 

 Marshall's note had put clearly, viz., that the gathering is 

 " fine H. atroviridis W. R. Linton." This is, no doubt, true, 

 for W. R. Linton's species, which was published as Epipadis 

 atroviridis, is intermediate between H. latifolia and H. atro- 

 rubens. I take no small blame to myself for having over- 

 looked the determination. My only excuse is that my usual 

 and best book of reference, Babington's Manual, Ed. IX., 

 does not refer to H. atroviridis. 



The species was created by W. R. Linton in his Flora 

 of Derbyshire (1903), where there is a plate, opposite p. 269, 

 which, in spite of its odd appearance, is sufficient to illustrate 

 the critical points which separate the form from its closest allies. 

 The description, on p. 270, is as follows (under the name of 

 E. atroviridis) : — 



' ' This plant is in some respects intermediate between E. latifolia and 

 E. atrorubens. It has the broad, rounded leaves of the former but rather 

 more numerous lanceolate leaves between the lower leaves and the flowering 

 spike ; the label is furnished with two side hunches and one median linear 

 hujich, descending lower than the side ones ; in size and robustness it is like 

 E. latifolia, its flowers are not rose-coloured or not so much as in E. atrorubens." 



Except that the colour of some of Mr Day's specimens 

 was well-marked, and the variability of their hunch-plication 

 was considerable, this description fits very well indeed to the 

 Gloucestershire plants under discussion. 



The probability is that we shall find that much of our 

 Gloucestershire aggregate E. latifolia, but not all, is this 

 particular segregate of W. R. Linton's, or, at any rate, nearer 

 to it than to any other described form. The greatest proba- 

 bility of all is that there is a pretty complete series of forms 

 running from extreme E. latifolia to extreme E. media ; the 

 latter of which, as found in England, has been declared by 

 Herr Freyn, the German botanist, to be merely a form of
