north to Burlington and St. Johnsbury, Vt., and North Woodstock, 
N. H. In Maine it is rare, known only from scattered stations, 
the northernmost of which is Anson and the most eastern Appleton 
and Union. Asplenium Trichomanes grows on ledges of various 
kinds of rock in southern New England. Further north it seems to 
prefer calcareous rocks. It is frequent in Vermont, occasional in 
southern New Hampshire and in western Maine. It apparently 
ascends to higher altitudes northward than the other species here 
placed. Athyrium angustum, var. elatius is known from scattered 
stations in other states, and along the Maine coast and on the 
Kennebee and upper Androscoggin Rivers, but not further north. 
(This generalization is based on 32 records.) Thelypteris cristata, 
var. Clintoniana is frequent west of the Connecticut, especially in the 
Taconie Mountains. It occurs here and there to the east, except in 
Rhode Island and on Cape Cod, as far as Mt. Desert. T. hexagon- 
optera is frequent in southern New England, occasional in 
Vermont, rare in New Hampshire (three stations) and occasional 
in Maine as far east as Charleston in Penobscot Co. T. simulata is 
known in Vermont only from Brattleboro and Hartland, but is 
occasional in southeastern New Hampshire north to Merrimac 
and southern Carroll Counties and in Maine along the coast to 
Southport and inland to Limington. It is abundant in eastern 
Massachusetts but apparently is less common in Rhode Island 
and Connecticut. Woodsia obtusa is frequent on ledges and in dry 
soil in southern New England; occasional in Vermont, reaching 
Burlington and St. Johnsbury; rare in southern New Hampshire; 
and in Maine known only from Winthrop (H. Metcalf, RHopora iii. 
236. 1901; specimen in herb. N. E. Botanical Club). 
Group B consists of species, rare or local with us, which enter 
New England from the southwest and are confined, except for one 
New Hampshire station for Lygodium, to the three southernmost 
states. Asplenium montanum is known from six scattered stations 
on granite ledges in Connecticut. A. pinnatifidum is reported from 
Sharon and Southington, Conn. The specimen from Southington 
in the Gray Herbarium, however, is not A. pinnatifidum, but a state 
of A. ebenoides with obtuse segments; that record may be founded 
on an error in determination. There seems no reason to doubt the 
Sharon report. Athyrium asplenioides is known from the Boston 
region and from Sandwich, Mass., and from Rhode Island and Con-
