The sori of Cheilanthes feei are elongate and they may be partially
hidden under the inrolled margins of the blade segments. The blades
are less than 3 cm wide, less than 20 cm long, but in Wisconsin are often much smaller. The blades are at least twice
pinnate, often 3 times pinnate at the base. The ultimate fertile
segments are nearly round in shape. The blades are conspicuously
pubescent with long hairs on the abaxial (lower) surface.
Cheilanthes feei usually grows on rocks, especially limestone
or sandstone. It's distribution is mostly west and south of Wisconsin,
and is limited mostly to the southwestern corner of the state,
plus an area along the Mississippi River north to Pierce County.
