New York Fern
Parathelypteris noveboracensis (L.) Ching

This is a common fern, and it often grows in large colonies that carpet the forest floor. Notice how the frond tapers toward the base, and the lowest leaflets are very small. This is a good marker for New York fern. Hayscented fern shares the delicate appearance of New York fern, as well as its habit of covering forest floors, but the shape of the fronds distinguishes these ferns. Hayscented fern fronds are triangular in outline -- broadest at the base, not tapering.
