    Type: South Africa, Cape Province, Thunberg s.n. (UPS, holo.)
    Habit
    Terrestrial.
    Rhizomes
    Rhizome scales to 4.5 × 1 mm, attenuate at apex. Rhizome erect or procumbent, to 4 mm diameter, with dark brown clathrate lanceolate pseudoserrate
    Leaves
    Fronds tufted, suberect, not proliferous, coriaceous, curling and inrolled when dry.
    Stipes
    Stipe redbrown, 4–20 mm long, with dense brown lanceolate acuminate scales to 2 mm long.
    Leaf lamina

    Pinnae
    Pinna 7–11(–15) pairs, oblong, to 2.5 × 0.9 cm, base adnate to free and auriculate, weakly undulate to pinnatifid with broadly oblong crenate segments, apex rounded. %Rachis covered in brown scales.
    Sori
    Sori several per pinna on each side of the costa but almost completely hidden by scales, linear, to 2 mm long.
    Figures
    Fig. 11, p. 70.
    Ecology
    Rock crevices and around bases of boulders, riverine thicket, always in sites that dry out for long periods; may be locally common; 1000–1950 m
    Conservation
    Widespread; least concern (LC)
    Note
    There have been proposals to split this taxon into several entities, but I have yet to see a key to such entities that works. Until that time, I will treat this as a single variable species. Schippers in Fern Gaz. 14, 6: 202 (1993) states he has seen this on a rock wall in North Pare, which would add T 3 to the distribution.
    Distribution
