The once-divided frond narrows towards the top but does not narrow significantly towards the base. The pinnae are spaced along the midrib, taper to a point and are four times or more longer than wide .
Round sori occur evenly around the entire edge of the underside of each pinna.
The species name of this fern comes from the even serrations around the edge of each pinna. In some moist high-light spots in Fern Forest dense growths of this fern reach head height.
