    Type
    Type: Sudan, Niamniam/Monbuttu border, Schweinfurth 3295 (B!, lecto., BM!, K (not found), iso.), chosen by ?Burrows
    Habit
    Terrestrial or lithophyte.
    Rhizomes
    Rhizome short-creeping, to 7 mm diameter, with dark brown subulate entire rhizome scales up to 5 mm long.
    Leaves
    Fronds shortly spaced, arching, narrowly deltoid, proliferous at base of terminal pinna (and sometimes on pinna costa) near the apex, thinly coriaceous.
    Stipes
    Stipe matt black, 12–35 cm long, set with brown subulate scales similar to rhizome scales, glabrescent.
    Leaf lamina
    Lamina ovate to deltate, 15–48 × 8–20 cm, 2-pinnate to 3-pinnatifid near the base of the lamina, the lowest pinnae longest, apical pinna similar to upper pinnae.
    Pinnae
    Pinnae dark green above, ovate or lanceolate in outline, up to 11 × 4.5 cm, unequally cuneate at the base, attenuate, progressively deeply divided towards the base into obcuneate or rhombic pinnules with the outer margins sharply serrate and irregularly shallowly incised, free pinnules with cuneate to narrowly cuneate bases, glabrous except for small lanceolate dark scales near the extreme base.
    Rachis
    Rachis matt brown, with occasional dark subulate scales, sulcate ventrally.
    Sori
    Sori along the veins, linear, 4–30 mm long.
    Indusium
    Indusium linear, narrow, membranous, entire, 0.3–0.4 mm wide.
    Figures
    Fig. 7: 1–2, p. 42.
    Ecology
    Moist forest; 900–1600 m
    Conservation
    Widespread; least concern (LC)
    Note
    I agree with Faden that in habit and cutting of the fronds this species most closely resembles the non-proliferous A. buettneri, which however has more dissected pinnae. However, in Zambia there are populations without gemmae – fide Kornaś.
