Information
Rhizome up to 7 mm. in diam., creeping or ascending, with tufted fronds and with linear-attenuate dark-reddish-brown clathrate entire to pseudoserrate scales up to 6 mm. long ending in a short hair-point. Frond usually arching, not proliferous, firmly herbaceous to thinly coriaceous. Stipe up to 28 cm. long, matt-brown, covered at first with a mixture of scales similar to those on the rhizome with numerous smaller almost hair-like scales when young often becoming subglabrous with age. Lamina up to 48 x 20 cm., 2-pinnate to 3-pinnate, oblong to lanceolate in outline, acute to broadly acute with the lower pinnae not significantly reduced. Pinnae up to 12 x 4 cm., lanceolate in outline, acute to caudate, divided into narrowly obcuneate to very narrowly oblong segments, the upper segments adnate and decurrent, irregularly incised and serrate towards their apices, glabrous ventrally when mature and often with copious hair-like scales on the dorsal surface. Rhachis dark-brown, covered with mostly hair-like scales but with some lanceolate scales similar to those on the stipe. Sori up to 8 mm. long, linear; indusium very narrowly linear, membranous, subentire.

Notes
A sterile depauperate form referable to the A. aethiopicum complex (Wild 6200 (BOL; SRGH)) was collected high on the main peak of Mlanje Mt. Its widely creeping rhizome with spaced fronds and shiny rhizome scales indicate that it may represent a depauperate form of either A. volkensii Hieron. or A. goetzei Hieron., or possibly an undescribed species.
