Description

The fern's leaves are up to about 30 centimeters long and a few wide, and are made up of segments subdivided into pairs of many-lobed smaller segments. They are pale green in color with glandular hairs.

The smallest segments are oval in shape and have sori with tan-colored sporangia on their undersides.
