    Type
    Type: Bioko [Fernando Po], Mann 338 (K!, holo.)
    Habit
    Terrestrial or rarely low-level epiphyte.
    Rhizomes
    Rhizome erect, less often creeping, short, with pale brown lanceolate subentire clathrate scales to 3 mm long.
    Leaves
    Fronds tufted (once descibed as spaced on a long-creeping rhizome, fide Faden), oblong-lanceolate, 15–60 × 3–9 cm, usually proliferous at apex.
    Stipes
    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
    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
    Rachis flattened, narrowly winged upwards, slightly scaly.
    Sori
    Sori elongate, many, closely parallel, almost reaching costa and margin, 2–10 mm long.
    Indusium
    Indusium membranous, entire or nearly so, narrow, to 0.5 mm wide.
    Figures
    Fig. 3: 8–9, p. 19.
    Ecology
    Moist forest, where may be locally common; 1000–1850 m
    Conservation
    Widespread; least concern (LC)
    Note
    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.
