BRITISH SPECIES AND SUBSPECIES OF POLYGALA. 173 
retain the specific rank of P. calearea, which is remarkably invariable, 
affording no well-marked varieties. It is istinctly calcareous in its 
habit, and much the most abundant on the chalk; it is recorded from 
Surrey, Sussex, Kent, Berkshire, Oxfordshire, Gloucestershire, Wilt- 
shire, and Dorsetshire. On the Continent its distribution is similar, 
throughout Central and Southern Europe. Our a is from a 
specimen gathered by myself on Box Hill, Surr

Great confusion has been imported into the Hee by the indisceri- 
minate use of the specific term amara for a great variety of forms, espe- 
cially for P. calcarea, a totally different plant. I thorou 
form of Linnzus’s P. amara, as exem in the Linnean herbarium, 
and I cannot distinguish from this Crantz’s P. austriaca, under which 
t has generally been ranged. Indeed, Reichenbach’s figu tf 
preceding species by the rosette of large fleshy leaves lying close
