SOME FERNS OF SOUTHWESTERN WISCONSIN 
Sister M. Ellen 
An attempt to discover and to identify the pteridophytic flora 
in the vicinity of Sinsinawa Mound (Grant County) was both in¬ 
teresting and attractive. The types of habitat in this locality are 
so varied within a radius of three or four miles that a fern lover 
might hope to find almost any or all of the native, temperate forms. 
These various plant habitats may be classified as follows: deep 
moist woods, dry open woods, wet rocky bluffs, tall limestone cliffs, 
and waste lands. 
It was somewhat disappointing but none the less interesting to 
find not a single plant of Polypodium vulgare, the common rock 
fern, which is so generally distributed throughout the state. . The 
Woodsias, rock-loving Aspleniums, Aspidium marginale, the Lyco¬ 
podiums, and other common forms were also hunted in vain. 
In the following list the nomenclature follows Gray^s Manual, 
seventh edition. 
POLYPODIACEAB 
Adiantum pedatum L.

Aspidium spinulosum (0. F. Muller) Sw. 
Occasional plants in deep woods. 
Asplenium Filix-femina (L) Bernh.

Camptosorus rhizopJiyllus (L.) Link. 
Three places on rocks; (a) on Sinsinawa Mound; (b) about 
three and one-half miles west of the Mound; and (c) about four 
miles southwest of the Mound. 
Cyst'opteris bulbifera (L.) Bernh. 
Very abundant on rocks. 
Cystopteris fragilis (L.) Bernh.
