About

Claytosmunda is a genus of fern. It has only one extant species, Claytosmunda claytoniana (synonym Osmunda claytoniana), the interrupted fern, native to Eastern Asia, Eastern United States, and Eastern Canada.

The specific epithet is named after the English-born Virginian botanist John Clayton. "Interrupted" describes the gap in middle of the blade left by the fertile portions after they wither and eventually fall off.
