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

    Type: Bioko [Fernando Po], Mann 338 (K!, holo.)
    Terrestrial or rarely low-level epiphyte.
    Rhizome erect, less often creeping, short, with pale brown lanceolate subentire clathrate scales to 3 mm long.
    Fronds tufted (once descibed as spaced on a long-creeping rhizome, fide Faden), oblong-lanceolate, 15–60 × 3–9 cm, usually proliferous at apex.
    Stipe green, canaliculate, 5–16 cm long, with narrow lanceolate scales.
    Leaf lamina
    Lamina subcoriaceous, 1-pinnate, the basal ones not decreasing in size, the middle ones opposite or alternate, decrescent towards apex.
    Pinnae in 7–20 pairs, subsessile, at right angles to rachis, lanceolate, 2–6 × 0.9–2.3 cm, base unequal, the basiscopic part cuneate, the acroscopic part cuneate and parallel with the rachis for a bit and there forming a lobe, margin deeply crenate, apex obtuse.
    Leaf veins
    Costa whitish, veins forked in and near acroscopic basal lobe but otherwise unbranched.
    Rachis flattened, narrowly winged upwards, slightly scaly.
    Sori elongate, many, closely parallel, almost reaching costa and margin, 2–10 mm long.
    Indusium membranous, entire or nearly so, narrow, to 0.5 mm wide.
    Fig. 3: 8–9, p. 19.
    Moist forest, where may be locally common; 1000–1850 m
    Widespread; least concern (LC)
    The material from the Taita Hills ( K 7) and the Uluguru Mts ( T 6) differs in that the sori do not stretch from very close to the costa to nearly reaching the margin – in these specimens they only occupy the upper 2/3 of the vein; also, the indusia are wider, to 0.8 mm, with wavy margin, and the stipe is slightly more scaly than in more Western specimens. The single specimen from the Udzungwa Mts ( T 7), however, is more like the Western populations! I have decided against subspecific status, but this was a fairly close call.
