Secondary rachises 1–3 mm apart. All pinnules alternately arranged, almost all at 908 to the secondary rachis. Pinnules wide oblong to semi-circular, bases not constricted, apices obtuse and broadly rounded. Fertile pinnules smaller than sterile pinnules; one central or distally offset sorus per pinnule.
