Woodwardia fimbriata Sm.
Giant Chain Fern, Giant Chainfern
Blechnaceae (Chain fern Family)
Synonym(s): Woodwardia chamissoi
USDA Symbol: WOFI
The plume-like fronds, several per crown, of this giant chain fern may attain 8 ft. in length. The bipinnate frond segments are coarse and large, lacking the delicacy of smaller ferns, but persisting in excellent condition until new fronds have uncoiled. The chain of worm-like sori on the underside of the frond give the plant its name.
