Also known as Adiantum aleuticum, the maidenhair fern (Adiantum pedatum) is an unusual fern that resembles plants more than ferns. The branches are palmately arranged and are where the leaves become fronds. Stipes can be dark purple or brown, 15 to 60 centimeters tall. The top of the stalk of the plant divides twice to create the fronds. The leaflets are fan or oblong shaped and are in a linear, consistent fashion with a little bit of tapering at the end of the frond, and are usually at right-angles to the stalk. Sori are oblong and on edges of leaflets.
