FERNS OF BALTIMORE 21 
Osmunda cinnamomea L., var. glandulosa Waters. 
The type locality is near Glen Burnie, Anne Arundel 
Co., where it was first seen in 1901. By July the char- 
acteristic glandular hairs had turned to a rusty brown, 
so that the plant seemed to be infected with a rust. 
This is what attracted attention to it. 
SCHIZAEACEAE. 
Lygodium palmatum (Bernh.) Swartz. This is not in 
the list of Sollers, but he afterwards knew of the chief 
station, a swamp on the turnpike from Baltimore to 
Washington. It is not found there any more. 
POLYPODIACEAE. 
Polypodium polypodioides (L.) Watt. Found in the 
District but not near Baltimore. : 
Lorinseria areolata (L.) Presl. A Coastal Plain plant, 
but there is one small patch in wet woods on the Pied- 
mont about 300 feet above sea-level. 
At Glen Burnie, where it is very abundant, there can 
be found many curious “obtusilobata” forms intermed- 
iate between the typical fertile and sterile fronds. There 
is nothing to indicate that they are the result of accident, 
like the corresponding forms of Onoclea sensibilis. 
Asplenium Bradleyi D. C. Eaton. Found by J. H. 
Brummell. Growing on a high rocky cliff and on 
neighboring rocks on the upper Patapsco River. 
Asplenium montanum Willd. On my first visit to the 
Bradleyi station this fern was found growing with It, 
but in much smaller numbers. These two species are 
now nearly if not quite extinct at this place. 
Asplenium ebenoides R. R. Scott. A single plant was 
found on an outcrop of limestone near Towson, Balto. 
Co. 
Asplenium pinnatifidum Nutt. This has not been 
found in the region, but it is not scarce on rocks along
