The term calciphile is here used in a somewhat general sense to 
cover all species whose ranges are, for the most part, identical with 
areas of calcareous rock. The actual lime requirements of the differ- 
ent species placed here probably differ considerably. Asplenium 
Ruta-muraria, for instance, is strictly confined to ledges of calcareous 
rock. Camptosorus and Thelypteris fragrans occur not uncommonly 
on other rocks. As shown by tests made by Dr. Edgar T. Wherry, 
of the Dept. of Agriculture, the former will grow in a weakly acid 
soil. Thelypteris Goldiana and Athyrium angustifolium are plants 
of rich woods, not always visibly associated with any source of lime 
other than leaf-mold. But it is probable that none of these species 
live in soils which do not contain soluble calcium compounds. 
Since the calcareous areas of New England are chiefly west of the 
Connecticut River, these species are most abundant there. The 
valley between the Green Mts. and the Taconics is a rich area for 
them, and so are Mt. Toby in Massachusetts and Smugglers’ Notch 
and the Willoughby Lake region in Vermont. Cystopteris bulbifera 
is the most widely distributed of these ferns east of the Connecticut, 
being known from Mt. Toby, from northern Coos Co., N. H., and 
from most of the calcareous areas in Maine. Cryptogramma Stelleri 
is probably next in abundance among the northern calciphiles, though 
in dry seasons it is likely to wither away early. It is very rare in 
western Connecticut, local in Franklin Co., Mass., and in eastern 
Vermont, and occasional in western Vermont. It has been found 
at Colebrook, N. H., by Dr. A. S. Pease and at West Paris, Maine, 
by W. L. Bacon (Rnopona x. 35. 1908). 
Asplenium viride has been found at five stations in the Green Mts. 
of Vermont and in 1917 at Green Mt. on the north branch of the 
Penobscot in Somerset Co., Maine, by Dr. Harold St. John. Woodsia 
glabella has six Vermont stations and two on ledges along the Andros- 
coggin at Berlin and Gorham, N. H. It also occurs at Moxie Falls, 
Somerset Co., and Chain of Ponds, Franklin Co., Maine. W. alpina
