Pinnae simple; lower pinnae shortly stalked, transition to decurrent pinnae in middle part of frond abrupt (over 2 or 3 pairs of pinnae); longest pinnae 8–38 mm long, 3–6 mm wide; rachis and pinna midvein without tubercles. Sori 0.5–2 mm long, 0.5–1 mm wide, discrete to laterally confluent when mature, in 1 row on each side of pinna midvein, sometimes part of a second row towards margin; inner nearer midvein, outer nearer margin.
