88 x Rhodora [May 
is found only at Queechee Gulf, Smugglers’ Notch and Mt. Willoughby 
in Vermont, though it closely approaches the Maine border in the 
Aroostook valley, New Brunswick. Thelypteris Filix-mas has been 
found at eight stations in central Vermont, where it thrives best in 
high pastures and thickets (see E. J. Winslow, The Male Fern in 
Vermont, Am. Fern Journ. vii. 87-90. 1917). T. fragrans is a fern 
of drier ledges (sometimes hardly calcareous) which occurs locally 
in the Green Mts. south to central Vermont, at Lake Sunapee and 
in gorges of streams north of the White mountains in New Hamp- 
shire and at scattered stations in Oxford, Franklin, Kennebec, Pis- 
cataquis and Aroostook Counties, Maine. 
The ranges of the two species of Pellaea overlap in Vermont, where 
P. glabella is known from six stations from Willoughby Lake to 
Pownal. P. atropurpurea crosses the Connecticut eastward to Mt. 
Toby and Berlin, Mass. (RHopora ii. 14. 1900), and occurs at Lin- 
coln, R. I., and Bolton, Conn., while occasional westward. 
Asplenium ebenoides is a rare hybrid reported from six places in 
Vermont, Sheffield, Mass., and Canaan, Berlin and Southington, 
Conn. A. Ruta-muraria is "scarce" on Mt. Toby and local in western - 
Berkshire Co. in Massachusetts, and occasional in western Vermont 
(with a single station at Willoughby) and western Connecticut, 
and occurs rarely on the trap ridges of central Connecticut. East 
of the Connecticut, Camptosorus was once found in Winthrop, Maine, 
by Haven Metcalf (Rnopona iii. 236. 1901). It has been collected 
at Hudson and Windham, N. H., at Weston and Natick (eradicated) 
and Needham near Boston, at Brookfield, Amherst and Mt. Toby, 
Mass., and at Lincoln, R. I., and at a few scattered stations in eastern 
Connecticut. West of the Connecticut it occurs at numerous sta- 
tions from New Haven, Conn., to the Canadian border, becoming 
locally common in the calcareous areas west of the Green Mts. 
Athyrium angustifolium is a rich woods calciphile, running north 
in Vermont to St. Albans and Danville and known east of the Con- 
necticut only at Alstead, N. H., and in the Mt. Toby region. Thelyp- 
teris Goldiana is a plant of similar habitats, but rather more common 
and with a wider range east of the Connecticut. It has scattered 
stations at Mt. Toby and in Worcester Co., Mass., at Alstead and 
in northern Coos Co., N. H., and in Franklin Co. and at Winthrop 
and Fairfield farther east in Maine.
