FERNS OF THE LAKE GEORGE FLORA—II 99 
were collected at Clarks Pond, west of Shushan, Sept. 
21, 1907. 
A form, the var. obtusilobata (Schkuhr) Torr., with 
sterile fronds, bearing a few abortive pinnae is occa- 
sionally met with, where the plants have suffered in- 
jury. ‘It was first detected, many years ago by Dr. 
Jed. Smith, in Salem.”’ Torrey’s, ‘Flora of the State 
of N. Y.’’ 2: 499. 1848. This fine specimen from 
Salem is preserved ‘in herb. Sartwell” at Hamilton 
College, according to Paine’s, “Catalogue of Plants of 
Oneida County and Vicinity.” N. Y. State Cab. 
Rep’t 18: 179. 1865. This form has also been found 
at Vaughns. 
PTERETIS NoDULOSA (Mx.) Nieuwl. 
Wet woods, usually in alluvial soil along larger streams 
in thickets; infrequent. July—Oct. 
Glens Falls (Hulst); Silver Bay (Kemp); Huletts 
Landing (Jelliffe); Hague (Mrs. E. Watrous); from 
French Mt., southern W. Fort Ann and South Bay 
southward to Round Lake, Coveville and Shushan. 
Along the Battenkill, near Shushan, fine plants grow; 
the sterile frond over 514 feet high and the stipe covered 
with a bloom. This fern is not so often met with in 
the western part of the region. 
Like the Osmundas, the numerous sterile fronds arise 
from stout ascending rootstocks: but the curious, 
dark-brown, firm, pinnate fertile fronds, do not appear 
until late in the season. The fertile fronds persist 
until the following spring. This fern was formerly 
known as Matteuccia Struthiopteris and Onoclea Struthi- 
opteris of American authors. 
Woopsta 1tvensis (L.) R. Br. 
Exposed granitic rocks on mountains; local. July-
