“C. radicans sub-species.” Syme, Eng. Bot., t. 41. The 
“radical” leaf added by J. E. Sowerby from Eng. "Bot, t. 2175. 
Arnott’s statement, positive Jee it be, is wrong. There 
were wild examples € existing in the Sm ithian and British 
Museum Herbaria, and it sees that Don suggested the name 
C. denticulata for it to Smith. The plant has been rediscovered 
near Rescobie by Mr. W. Graham and I have also seen it in 
Inverness-shire near Loch Morlich, in south Aberdeenshire 
near Invercauld, in Ross-shire at Dundonn ell, and in 
Caernarvonshire at Llanberis. It is probably widely spread. 
The plate of it in the Linnean Transactions is perhaps the 
reason why it is not more generally pigs from 2a fact 
be 
that the leaf which is figured, is as one the 
radical leaves of the main stem. I think wt is a lower leaf 
from one of the rooting nodes of the stem, as these usually 
present the triangular outline, whereas the Sar radical leaf is 
only rarely of that shape. The chief characters appear to me 
to be the uniformly rooting stem, and the narrower sepals. Itis 
always found in shady places, growing in rich mud, and usually 
at the base of high mountains, or in sub-alpine localities.
