    Aspleniaceae, Henk Beentje. Flora of Tropical East Africa. 2008

    Type
    Type: Rwanda, “Bugoier forest SE of Kissenje”, Mildbraed 1460 (B!, holo.)
    Habit
    Terrestrial, occasionally a low epiphyte or lithophyte.
    Rhizomes
    Rhizome erect or shortascending, to 9 mm diameter, with dark brown Rhizome scales with cordate base, ovate-oblong or elongate-deltoid, acute to long-acuminate, margin pale brown, entire or rarely fimbriate, dark, pellucid, to 6 × 2.5 mm.
    Leaves
    Fronds tufted or occasionally shortly spaced, often with subterminal gemmae.
    Stipes
    Stipe dark green above, black beneath, 11–23 cm long, with scales similar to rhizome scales (but smaller) dense near base and sparse elsewhere.
    Leaf lamina
    Lamina dark green, ovate-lanceolate in outline, (20–)30–50 × 8–20 cm, 3-pinnatisect (to slightly 4-pinnatisect), acuminate, the apical part gradually decrescent.
    Pinnae
    Pinna shortly stalked, in 13–23 pairs, the basal ones hardly smaller and (sub)opposite, the upper ones alternate, elongate-deltoid, to 8 × 4(–10 × 5, fide protologue) cm, 2-pinnatisect, acroscopic base truncate, basiscopic base cuneate. %Pinnules in 6–12 pairs; the ultimate segments falcate-oblong and to 8 × 1.5 mm; scales sparse, as on rachis.
    Rachis
    Rachis narrowly winged, glabrous or with sparse dark brown scales to 2 mm, the margins with hair-lobes.
    Sori
    Sori 1(–2) per segment, on the vein, 1.5–4 mm long.
    Indusium
    Indusium membranous, entire, 0.4–0.5 mm wide.
    Figures
    Fig. 7: 9–11, p. 42.
    Ecology
    Moist forest and bamboo forest, nearly always in damp sites such as stream-banks, often associated with Cyathea; may be locally common; 1650–2550(–3000?) m
    Conservation
    Widespread, Least Concern (LC)
    Note
    The specimens from U 2 differ slightly in having the first acroscopic pinnule less developed. A specimen from Kenya, Kiambu District: Aberdares, Royi, Mar. 1921, Gardner 1266! differs in the slightly narrower ultimate segments, and the distal, unlobed pinnules of the middle pinnae often at an angle of 70–90° to the costa, while those of A. bugoiense are usually at 45–60°. This is Asplenium sp. C of Faden. Gillett 16703 from K 5 Kaimosi looks like this taxon but lacks frond tips, so identification is not quite sure. Specimen ( Faden 69/2019!) sterile, but most likely A. bugoiense; frond cutting differs slightly, but not much. The much-lobed first acrocopic pinnule also features in several specimens of A. loxoscaphoides.
