    Type
    Type: CongoKinshasa, Ninagongo, Mildbraed 1369 (B!, syn.); Rwanda, Kahama, Mildbraed 1779 (B!, syn.); Tanzania, Usambara, near Magamba above Kwai, Engler 1288 (B!, syn.)
    Rhizomes
    Rhizome short-creeping, with two types of Rhizome scales plus intermediate ones (HB: no, all the same); dark brown, ovate to narrowly triangular, acuminate, ending in hair-tip, 1–4 × 0.5 mm, from cordate or peltate base, with paler margin.
    Leaves
    Leaves spaced, 50–80 cm long, 3-pinnatisect.
    Stipes
    Stipe black, 25–33 cm long, to 2 mm thick, glabrous or nearly so.
    Leaf lamina
    Lamina oblong in outline, 25–40 × 9–12 cm, apex decrescent.
    Pinnae
    Pinna 15–20, 2-pinnatisect, deltoid-ovate or deltoid-oblong, to 7.5 × 3.5–4 cm. %Pinnules trapezoid-rhombic, to 2 × 1–1.3 cm, base cuneate, the ultimate segments spatulate with (sub-)truncate and denticulate apex; scaly when young with scales similar to those of rhizome.
    Rachis
    Rachis with ovate (Kivu) or thread-like and lobed (Ninagongo, Usambara) scales.
    Sori
    Sori lateral on veins, 2–5 mm long, not reaching margin.
    Indusium
    Indusium entire, to 0.4 mm wide.
    Ecology
    Montane or bamboo forest, alpine zone; 2300–3000 m
    Conservation
    Fairly widespread with a wide habitat and altitude range; Least Concern (LC)
    Note
    This is close to A. praegracile but differs in pinnule shape, which is narrow in praegracile, spatulate in mildbraedii; and apical lobes are thin and deep in praegracile, spatulate and rather shallow in mildbraedii. Chaerle in his unpublished thesis, p. 200, treats it as a full species; and keys it out as having fronds up to 2-pinnate-pinnatisect, as opposed to praegracile which he has as up to 3-pinnate or more finely dissected. Chaerle adds as syntypes Libusch s.n. from Lutindi, and von Goetzen 43 from Ninagongo; but Hieronymus only placed these incomplete/juvenile specimens tentatively in this taxon. The protologue only likens it to A. furcatum Thunb. var. tripinnatum Baker (± aethiopicum) and says it is very like A. goetzei var. major (now a synonym of actiniopteroides) “but with much smaller rhizome scales.”
