The sterile frond is pinnately compound with pinnae to 60 cm in length and opposite or subopposite in position. The pinnae are lanceolate, with an acute pinnae apex, an entire (repand margin) and oblique base.
The fertile fronds similar in shape and size as sterile fronds but more erect. All pinnae have sporangia. The sporangia cover the entire abaxial surface of the pinnae.
