PTERETIS NODULOSA (Micux.) NrbuwLtanp.—The 
American ostrich fern, which is essentially boreal in 
distribution, is one of the rarer ferns in the vicinity of 
Washington, D. C., occurring on a few islands of the 
Potomac River and on alluvial bottoms of both the 
Maryland and Virginia sides. The Virginia locality, 
in Fairfax County, was recorded in 1899? as a new 
southernmost one for this species. The southern range 
may now be extended by the record of specimens re- 
cently collected in West Virginia, as follows: Abundant 
in a meadow along Dry Fork, a branch of Cheat River, 
at a point about 3 miles south of Horton, Randolph 
County, West Virginia, July 10, 1918, #. T. Wherry & 
H. W. Trudell. A specimen of this collection has been 
deposited in the National Herbarium by the collectors. 
PELLAEA ANDROMEDAEFOLIA (KAvLF.) FEE.—This 
species, which is abundant at low altitudes through a 
large part of California, from Mendocino and Tehama 
counties southward to Lower California, occurs also 
in southwestern Oregon. The record is based on a 
characteristic specimen in the herbarium of the Oregon 
Agricultural College at Corvallis, collected at Roseburg, 
Oregon, in April, 1887, by Thomas Howell and labeled
