The calciphiles are very interesting, from the closeness with which 
they follow the calcareous rocks. They seem to depend on lime in the 
soil. The northern group contains species abundant north and west 
of New England. Clematis verticillaris is the most generally dis- 
tributed of these, for it does not depend entirely on substrata for its 
lime, but finds it sometimes in rich humus on other rocks, as on quart- 
zite at Killingly, Conn! Anemone riparia seems to have sought out 
calcareous areas throughout, although especially abundant in Aroos- 
took County and western Vermont. A. canadensis is-abundant in 
the alluvium of the St. John and Penobscot valleys in Maine, in the 
Champlain region and in the Housatonic valley. The stations in 
eastern Massachusetts seem to be introduced. 
Thalictrum confine, discovered at Van Buren, Ft. Fairfield and 
Caribou, Maine, by Prof. M. L. Fernald, has also been found on ledges 
along Lake Champlain, from Ferrisburg to North Hero. Anemone 
multifida, var. hudsoniana grows in ledges of the St. John River at 
St. Francis and by the Fish River at Fort Kent, and at Aroostook Falls 
in New Brunswick. This was also found by Robbins and others in the
