Hab. — Wet places in woods, often in alder- thickets near stream- 
lets or ponds. Discovered near Lowell, Massachusetts, by Mr. William 
Boott as early as 1843, ^•Bd since found by several collectors near 
Fresh Pond, Cambridge, in Middlesex County, near Amherst and near 
Pelham, all in the same State. Mr. Frost has it near Brattleboro, ; I 
have found it in more than one place in Connecticut; it occurs in 
central and southern New York, and Mr. A. Commons has sent it from 
the vicinity of Wilmington, Delaware. It is known to occur in England, 
in Continental Europe, and in Siberia. 
Description: — In the structure of the root-stock, and in 
its mode of growth there is nothing to distinguish this fern 
Mr. Moore’s character read’s thus: — '■'•Fronds variouSy early fertile ones tally 
erecty narroWy linear-lanceolate, bipinnate below witk oblong-acute adnate inciso-serrate 
or lobed pinnules having aristate inczirved teeth; barren ones shorter, with oblong 
bluntish pinnuleSy adnate or decurrent ; later fertile ones broader, with oblong bluntish 
crenato-serrate pinnules ; anterior and posterior basal pinnules of the lowest pinnae 
nearly equal in size ." — Mr. Moore’s plate well represents the three kinds of fronds he 
describes, all taken from a plant brought by .Mr. John Lloyd from Oxton bog, Notting- 
hamshire.
