Venation anadromous to catadromous, obscure, ending in the teeth near the margin. Stomata mostly of the polocytic type, (40-)52(-66) mm long. Sori circular, to 1.2 mm in diameter, medial on unmodified anadromous vein branches, the sporangia often confluent at maturity; sporangia stalks simple or glandular, the capsule with (11-)14(-17) indurated annulus cells, the epistomium 5(-6)-celled, the hypostomium 5(-7)-celled. Indusia brown, firmly herbaceous, reniform, to 1.6 mm in diameter, entire to erose, often with a few scattered glands along margin. Spores ellipsoidal, monolete, the perispore forming tubercules and short ridges, ruminate, (38-)43(-48) x (26-)31(-36) µm.
