Longest petiolules 8-40 mm long. Pinnae deltoid or linear-triangular. Pinnules or pinnalobes narrowly ovate, ultimate leaflets only shallowly lobed, rhomboid, ultimate segments 0.5-3 mm long. Veins in sterile ultimate lobes frequently simple, not reaching the margin, false veins not present. Sori frequently single on a segment, terminal at the vein endings.
