    Type
    Type: South Africa, Cape Peninsula, Thunberg s.n. (UPS, holo., seen by Schelpe)
    Rhizomes
    Rhizome widely creeping, up to 56 cm long, 2–3 mm in diameter with dark brown ovate somewhat undulate rhizome scales up to 2 mm long blackening with age
    Stipes
    Stipes stramineous, black at the base, 15–50 cm long
    Leaf lamina
    Lamina lanceolate to broadly lanceolate in outline, 25–55 cm long, 21 cm wide, deeply bipinnatifid, acute at apex, the basal pinnae slightly reduced.
    Leaves
    Pinnae narrowly oblong, 4–11 cm long, 0.6–2 cm wide, deeply lobed, the lobes oblong, 0.3–1.4 cm long, 3–5 mm wide, glabrous, glandular or thinly pilose beneath and with thin cinnamon membranous ovate scales along the costa beneath. Fronds spaced up to 5 cm apart, 0.35–1.05 m tall

    Costa grooved above, glabrous; veins in sterile fronds mostly forked, in fertile often simple

    Figures
    Fig 6, p 23
    Ecology
    Swampy areas, quaking Sphagnum bogs, Typha, Papyrus, Cyperus marshes but sometimes in seasonally drier areas, vleis banks and ditches, Syzygium forest; (0–)900–2400 m (see note)
    Note
    Holst 2567 (Tanzania, Amboni, June 1893) is from a much lower altitude (probably ± sea level) than any other East Africa specimen seen. It is curious it has not been collected again from such a well known area. Only one specimen seen for Nigeria, Bowden 71 (Sardauna Province, Mambila Plateau, valley near Maya–Ndaga, 6 Apr. 1970).
