    Type
    Type: Ethiopia, Mt Selki [Silke], Schimper 679 (B!, holo.; K!, iso.)
    Habit
    Terrestrial, lithophyte or low/medium epiphyte.
    Rhizomes
    Rhizome erect, dark brown, with Rhizome scales mid- to dark brown, linear and attenuate, to 5.5 × 0.8 mm, margin entire, apex attenuate.
    Leaves
    Fronds tufted, erect, not proliferous, herbaceous.
    Stipes
    Stipe dark brown, purplish or black, 3–30 cm long, at the very base with scales similar to those of the rhizome, otherwise glabrous.
    Leaf lamina
    Lamina membranous, delicate, bright green, ovate to lanceolate in outline, 10–40(–70) × 5–20 cm, 3-pinnate, the lowermost pinnae reduced, decrescent towards the apex.
    Pinnae
    Pinnae mid-green, narrowly triangular in outline, up to 11 × 3.5 cm, unequally cuneate at base, attenuate, divided into ovate or rhombic-ovate pinnules, these lobed to pinnate, the acroscopic base parallel to the rachilla, the basiscopic base attenuate, the ultimate segments obovate, with rounded to obtuse apices, glabrous or with sparse scales to 0.1 mm long.
    Rachis
    Rachis brown with thin green wings, glabrous or nearly so.
    Sori
    Sori 1–2 per segment, inserted on the veins and facing towards the costule, ovoid, 0.5–2 mm long.
    Indusium
    Indusium half-circular, membranous, entire, 0.7–1 mm wide.
    Figures
    Fig. 10: 5–6, p. 62.
    Ecology
    Moist forest, bamboo zone, Hagenia woodland, occasionally in moorland, but always in damp sites, along streams; (1350–)1800–3150 m
    Conservation
    Widespread; least concern (LC)
    Note
    A specimen from Tanzania, Mt Meru, Dec. 1966, Richards 21572! is very similar but more dissected: it is 4-pinnatisect. The lamina is 53–65 × 14–28 cm, pinnae are up to 14 × 7 cm, and the indusium is 0.3–0.4 mm wide. It came from moist forest at 2220 m, on the bank of a small stream. A. kuhnianum falls well within the variability of this taxon, and I have made it into a synonym.
