Osmunda claytoniana
Osmundaceae
Interrupted fern gets its name from the brown fertile leaflets, which "interrupt" the green sterile leaflets on the larger fronds. This fern is unusual in that its sterile, three-foot tall fronds have brown spore cases in the middle with green pinnae both above and below. The fairly blunt tips of the leaflets; this characteristic helps distinguish interrupted fern from its relative, cinnamon fern, which has very pointed tips. Interrupted fern performs best in a shady site with moist soil, but it does better in higher light and drier soil than most ferns.
