Description |
Rhizome shortly creeping, 2–3 mm thick; rhizome scales very narrow, chestnut brown. Fronds close or tufted, thin. Stipe straw-coloured, 10–40 cm long. Lamina narrowly oblong in outline, 0.3–1.5 m long, 8–50 cm wide, 2–4-pinnate and pinnatifid. Primary pinnae in about 10–20 pairs, the longest up to 40 x 12 cm, with petiolules up to 2 cm long; ultimate pinnules almost linear, up to 4 x 0.75-1.25 mm, slightly spreading apart, not widened at the apex, uninerved, each with only 1 sorus. Rhachis straw-coloured. Indusium pocket-like, attached by the side, 0.3–0.5 mm long and wide. |
Notes | Kramer mistakenly referred Stolz's specimen to Malawi where he never collected (F.T.E.A., Verdcourt, 1999), so occurance in Malawi in Roux (2009) probably wrong! |
