Wilford's hayscented fern
The rhizome is long and crawls sideways, with a diameter of about 4 mm and brown pubescence. The petiole is about 5 to 30 cm in length, and the upper part is green to straw-colored, and it is dark brown and glossy toward the base. However, it is often reddish brown throughout. The leaf blade is 10 to 30 cm long and 3 to 8 cm wide and has a generally elliptical lanceolate shape, with a cut from twice to three times pinnate compound leaves. It is bright green and grassy. The wings are broad-oval and have a short handle. The lobes are deeply cut and oblong in the shape of a lanceolate, with sharp or dull teeth at the edges. At first glance it looks hairless, but small hairs are sparse enough to be visible when viewed with a loupe. There are many variations in leaf shape and cutting conditions, and leaves without sporangia tend to be small and shallow. However, the shape of the envelope is not clearly cup-shaped like other species of this genus, but rather looks like a pocket on the leaf blade side.
