Blotiella natalensis

Rhizome erect or creeping, often massive and woody, 1.5–2.5 cm diameter, covered with pale or reddish brown hairs 5–10 mm long. Fronds tufted or closely spaced, 0.6–2.6 m tall; stipe straw-coloured, up to 0.7(–1) m long with dense pale hairs when young but becoming glabrous; lamina lanceolate, narrowly oblong or triangular in outline, up to ± 1.5 m long, either 1-pinnate, 1-pinnate with a few lower pinnae having several free pinnules, or distinctly 2-pinnate; rachis pubescent, eventually slightly roughened by hair-bases, becoming glabrous below; terminal pinna ± hastate, pinnatifid and terminal segments of lateral pinnae similar with ± 7 pairs of lobes; pinnae narrowly oblong to narrowly triangular, (7.5–)18–31 cm long, (1.5–)3–12 cm wide, stalked, deeply pinnatifid with lobes lanceolate-triangular up to ± 4 cm long and 1 cm wide, narrowly joined at bases; in 2-pinnate fronds the pinnae have a deeply crenate terminal segment gradually passing into distinct pinnules which are narrowly triangular or lanceolate, 4.5–7.5 cm long, 1.5–2.2 cm wide, sessile, entire to wavy crenulate or pinnatifid; surfaces sparsely to densely pubescent with adpressed hairs, the costa with short pubescence even if surface glabrescent. Sori ± rounded, in sinuses between lobes of pinnules or pinnae but in more dissected fronds also in shallow sinuses of lobed margins of pinnules or pinna-lobes, up to ± 10 per pinnule and in places sometimes appearing almost continuous; paraphyses 0.2–0.4 mm long, thin, the apical cells brown, ellipsoidal, rounded or pointed.
