    Type
    Type: Tanzania, Kilimanjaro, Peters’ Hut to Bismarck Hut, Peter 1084 (B!, holo.; K!, iso.)
    Habit
    Lithophyte, terrestrial or occasionally epiphyte.
    Rhizomes
    Rhizome long-creeping, 2–5 mm diameter, with dense dark brown lanceolate subentire scales 3–6 × 0.8–1.2(–2.8) mm, ending in a hair-tip. Fronds spaced, sparse, erect, not proliferous.
    Stipes
    Stipe 10–30 cm long, with a few to many scales 1.5–2 mm long, usually also with rather dense stalked glands.
    Leaf lamina
    Lamina dark or dull green, sub-coriaceous, narrowly ovate in outline, (6–)7–28 × 3.5–18 cm, 2-pinnate to 3-pinnatifid, rarely 4-pinnatifid.
    Pinnae
    Pinnae in 5–19 pairs, obliquely ovate or trapezoid, to 5 × 2.5 (–9 × 4.5) cm, the basal ones largest, apex decrescent.
    Pinnules
    Pinnules deltate, pinnatisect, with 2–7 segments, the ultimate segments with 2–4 narrowly linear obtuse apices to 0.4 mm wide, with occasional scales.
    Rachis
    Rachis rather densely scaly with long-attenuate scales, often (?always) with rather dense stalked glands – but these often absent on young/infertile fronds.
    Sori
    Sori 1–2(–3) per pinnule or lobe, linear, 1.5–3.5 mm.
    Indusium
    Indusium present, entire, 0.2–0.5 mm wide.
    Figures
    Fig. 8: 7–8, p. 47.
    Ecology
    From the upper part of the forest through Hagenia woodland and heath zone to upper moorland, where restricted to rock crevices; terrestrial, epiphytic or lithophytic; 2500–4250 m
    Conservation
    Fairly widespread with a wide altitude range; Least Concern (LC)
    Note
    A. majus differs from actiniopteroides in the slightly wider rhizome scales, but not enough to keep the two apart; I have studied the types and decided to treat A. majus as a synonym. Chaerle in his unpublished thesis: p. 191 treats A. majus as a full species, distinguishing the two by stipe length and glandular covering, as well as in ecological preference. Gland cover is variable: they are missing in Hedberg 1289, which otherwise is a perfect match; there are few on Hedberg 2303 and Grimshaw 93/262; and only present on part of Wood 173. Peter spells the epithet as actinopteroides; U.K.W.F. (1974) has actiniopteroides. Chaerle, in his unpublished thesis, p. 73 explains why he believes that the spelling by Peter was a typographical error, and corrects it to ‘ actiniopteroides’. I believe he is right, and I have followed his suggestion. This taxon resembles A. uhligii but the lamina is usually ovate-deltoid and more finely dissected; dark scales and glandular rachis are best distinguishing features.
    Distribution
    Range: Probably also occurs in Congo-Kinshasa, restricted to Ruwenzori, Virunga, Mt Elgon, Nyandarua/Aberdares, Mt Meru and Kilimanjaro Range: Rwanda Flora districts: U2 U3 K3 T2
