2-pinnate, with obtuse divisions and narrow toothed 
segments; midveins disappearing by continued 
branching; fertile portion 2-3-pinnate, often much 
branched ; spores tuberculate ; bud for the follow-

apex of both sterile and fertile portions turned 
down in vernation. 
In grassy woods and swamps, Nova Scotia to New

varying from round-reniform to ovate-lanceolate, 
their margins entire or finely incised; bud for the 
following year pilose, enclosed in the base of the stem;

to Florida, west to California. Also in Europe, eastern 
Asia and Australia. The sterile portion is persistent 
through the winter. Sept.—Dec. 
Varies greatly ; the large forms are known as var. aus- 
trale, smaller forms with obliquely lanceolate segments 
as var. obliguum, similar forms with finely dissected seg- 
ments as var. d/ssec/um, and small forms with roundish- 
reniform segments as var. /unarioides.
