20 AMERICAN FERN JOURNAL 
In 1837, Dr. Wm. E. A. Aikin published a catalog 
of the plants found in the vicinity of Baltimore. In 
1888, Basil Sollers, a most enthusiastic amateur well 
known to the writer, published a ‘Check List of Plants” 
found in the same region. In this list are all the plants 
mentioned by Aikin, as well as those in Ward’s “Flora” 
of the District of Columbia, because the latter were 
to be looked for near Baltimore. My account includes 
data from Aikin and from Sollers. 
OPHIOGLOSSACEAE. 
Ophioglossum vulgatum L. Found in only a few 
places and always in damp woods. It has never been 
seen in the open grassy situations where it is so frequently 
found in New England. 
— Botrychium  virginianum (L.) Swartz. The dwarf 
fruiting forms, 4 or 5 inches high, which were ill-advisedly 
called B. gracile Pursh, occur in places where the condi- 
tions appear not to be the most favorable. 
Botrychium obliquum Muhl., var. oneidense B. D. 
Gilbert. This was found two or three times in wet 
soil in thick woods. 
Botrychium neglectum Wood: The discovery of three 
or four dozen plants east of Towson, Balto. Co., was a 
definite extension of the southward range of this fern, 
unless the fern found by Egerton near Ellicott City, 
Howard Co., and called B. simplex, was really neglec- 
tum. The plants found near Towson were in a little 
thicket at the edge of open woods. 
Botrychium simplex E. Hitchcock. See note above. 
The writer was told by Egerton that the few plants 
were in the corner of a field in which cows were pastured, 
so that the station was destroyed. 
OSMUNDACEAE. 
Osmunda regalis L. Plants growing in dense shade 
have pinnules much resembling the leaflets of the honey 
locust.
