Osmundaceae 
OSMUNDA REGALIS L. 
This fern is frequent throughout the region in swamps, 
damp old fields and woods. May—Aug. 
It is often found growing in shallow water about the 
margin of sphagnum marshes, where it attains the 
height of 6 feet. 
OSMUNDA CINNAMOMEA L. 
Low grounds and swampy woods; common. May-— 
une, 
A tall fern with a large rootstock, from which spring 
a circular cluster of fronds. The fertile fronds unroll 
in the early spring: the sterile do not attain their growth 
until in the summer. Sometimes confused with Clay- 
ton’s Fern, when not fruiting: but the base of the 
stipes retain some of the ferruginous wool: and the 
sterile pinnae with small tufts of tomentum at their 
bases, are thicker, darker green, and the segments 
less obtuse. 
The form rronposa (Torr. & Gray) Britton is occa- 
sionally met with; the fronds may be sterile below or 
above or on one side. This fern was first noted in 
swamps at Cambridge in Lewis C. Beck’s “Botany of 
the Northern and Middle States,’ 1st ed.: 457. Al-
