Laminae papery, brownish green or yellowish green when dried, adaxially shortly hairy along costae and veins, abaxial surface with short hairs along costae and veins, also with minute spherical sessile yellow glands along veins. Sori orbicular, marginal, sterile on proximal 2 or 3 pairs of veins, sometimes only top 2 or 3 veins fertile; indusia glabrous. Sporangia bearing golden glands on stalks. Spores cristate. 2n = 144.

The epithet is derived from "Aspidium terminans" (Wallich, Numer. List, no. 386. 1829; Kunze, Linnaea 23: 230. 1850), which is a nomen nudum and was not therefore validly published (Melbourne Code, Art. 38.1(a)).
