(Report Bot. Exch. Club, 1913, p. 475). The figure which 
I referred to A. vulgare belongs, I am fully convinced, to that 
species, and Dr. Moss agrees that there can be no doubt whatever

The general Secu of my re-examination and survey of all the 
evidence is therefore that, while I have modified my opinions 
regarding A. nemoroswm Lejeune and L. Arctiwm Hill, there is no 
further change to be made in nomenclature, and the names in my

of thie British forms. Though it is not yet possible to come to any 
final conclusions on this matter, it seems to be strongly indicated

for chalk or limestone, while A. vulgare seems to avoid the lightest 
soils. The former may have been accidentally introduced in 
some of the vice-counties given below

botanists will send to the author (9, Harvey Road, Cambridge) 
fresh unpressed specimens from the vice-counties not indicated, 
in order that later lists may be much more full and perfect. One
