    Type
    Type: South Africa, Cape, ?Grahamstown, Hesse s.n. (?LE, holo.)
    Habit
    Terrestrial, epilithic or epiphytic, 60–120 cm tall.
    Rhizomes
    Rhizome erect, to 30 mm diameter with grey-brown to black, lanceolate acuminate irregularly fimbriate rhizome-scales, 9–14 × 2–3 mm, composed of thin-walled cells.
    Leaves
    Fronds tufted, arching, somewhat fleshy, to 80 cm long.
    Stipes
    Stipe matt-grey to brown above and green below, canaliculate, 20–30 cm long and 3 mm diameter, at first densely clothed with subulate clathrate subentire or fimbriate scales, gradually becoming subglabrous.
    Leaf lamina
    Lamina oblong-lanceolate, 1-pinnate, 40–100 × (14–)20–26 cm, bearing a gemma or small plant at the base of the apical pinna - some fronds lack gemmae but at least some proliferous fronds usually present.
    Pinnae
    Pinnae in 6–12 pairs, alternate, coriaceous when fresh, dark green and shiny above, lanceolate to narrowly elliptic, 10–19 × 2–5.2 cm, petiolate, unequally cuneate at the base with the acroscopic base parallel to the rachis and the basiscopic one cuneate, margin subentire to minutely and regularly shallowly crenate, acuminate, glabrous or nearly so. Basal pinnae slightly reduced, terminal pinna similar to other pinnae.
    Leaf veins
    Veins forked.
    Rachis
    Rachis matt-greygreen, narrowly winged in the upper 1/2 or not winged, subglabrous as the stipe.
    Sori
    Sori many, equally spread along the veins at 45° to midrib, 5–19 mm long, usually extending from near the costa halfway to the margin.
    Indusium
    Indusia linear membranous, entire, ± 1 mm wide.
    Figures
    Fig. 3: 1, p. 19.
    Ecology
    Moist forest, terrestrial, on rocks or a low epiphyte; 1050–2250 m
    Conservation
    Widespread; least concern (LC)
    Note
    Luke & Luke 5053a has only few sori, near the base of each pinna. Grimshaw notes that above 2100 m on Kilimanjaro this taxon is replaced by Asplenium sp. B of Johns, = A. boltonii, with which it seems to intergrade. This species can be confused with boltonii (but has entire or crenate pinnae), and anisophyllum (but has gemmae near apex).
