    Aspleniaceae, A. H. G. Alston. Flora of West Tropical Africa. Ferns and Fern-Allies Supplement. 1959

    On trees in forest; up to 600 ft. alt.

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

    Type: Benin [Oware kingdom], Palisot de Beauvois s.n. (P, holo., not found)
    Epiphyte or lithophyte.
    Rhizome erect or shortly creeping (fide Faden), short, fleshy, with lanceolate clathrate (dark brown cell walls, translucent lumen) rhizome scales to 11 × 1.5 mm, margin entire to sinuate or crenate (not crenate in our specimens), apex attenuate and ending in a hair-tip.
    Fronds tufted, drooping.
    Stipe thick, canaliculate, gradually attenuate from lamina but sometimes seemingly to 25 cm long, with a few scales at the very base.
    Leaf lamina
    Lamina slightly fleshy, lanceolate or strap-shaped, 25–100 × (2.2–)3–8 cm, entire, base attenuate, apex attenuate, glabrous.
    Leaf veins
    Costa clear, flattened. Veins many, free, forking, 6–7 per cm, at angle of 45–70° with costa.
    Sori many along the veins, linear, long ones alternating with occasional short ones, 9–30 mm long, reaching neither costa nor margin.
    Indusium membranous, entire, pale, to 0.7 mm wide.
    Fig. 1: 6, p. 9.
    Moist forest, often near water, (low) epiphyte or occasionally on rocks; 1000–1550 m
    Widespread; least concern (LC)
    Chandler 2445a from U 4, Sezibwa Falls, has a very small fronds but has sporulating sori; the lamina on fertile fronds can be as small as 12 × 0.8 cm. Rhizome scales and general look indicate that this is an extreme form. Dummer 2728 from Uganda has some leaves with narrowly triangular outgrowths to 25 mm long on the margin; again, a form rather than a new taxon. Johns split off Faden 70/39 as species A of his checklist, without indicating any differences. I believe it is the same taxon.
