Morphology Leaves Stipes
Stipe proximally castaneous, brown to stramineous higher up, up to 49 cm long and 10 mm in diameter, near base with dense stramineous to ferrugineous narrowly lanceolate to filiform scales up to 40 × 7 mm, with long twisted filiform outgrowths and often also with scattered glands, scales higher up fugaceous.
Morphology Leaves Leaf lamina
Lamina herbaceous, ovate to ovatetriangular, up to 78 cm long, 2-pinnate to 3-pinnate.
Morphology Leaves Rachis
Rachis stramineous, becoming narrowly winged towards apex, with fugaceous narrowly lanceolate to linear scales up to 7 × 2 mm.
Morphology Leaves Pinnae
Pinnae in up to 16 stalked pairs, basal pinna pair inaequilaterally ovate to oblong-acuminate towards lamina apex, basal pair longest, mostly basiscopically developed, up to 315 × 185 mm, with up to 9 stalked pinnule pairs; pinna-rachis narrowly winged distally, abaxially with scales up to 5 mm × 1.6 mm and hairs of three types (unicellular, bicellular and pluricellular simple or branched).

Pinnules lanceolate to oblong-acuminate, basiscopically decurrent, acroscopic pinnule on basal pinnae up to 90 × 35 mm, basiscopic pinnule on basal pinnae up to 112 × 42 mm; segments ovate to oblong-obtuse, basiscopically decurrent, up to 22 × 9 mm, lobed, lobes serrate, adaxially glabrous, with oblong glands along and between veins, or with a few hairs along costule, abaxially sparsely set with glands and hairs mostly along costule and veins
Morphology Reproductive morphology Sori
Sori medial on predominantly anadromous vein branches, discrete, circular, up to 1.8 mm in diameter at maturity, essentially uniseriate; sporangium stalk simple, or with one or more glandular cells, but mostly with a long multicellular, uniseriate hair; indusium persistent, pale brown, firmly herbaceous, reniform, entire, repand, or erose, (rarely glandular along margin), often strongly revolute, up to 1.8 mm in diameter
Morphology Reproductive morphology Spores
Spores with perispore folded into tubercules or reticulate ridges, finely rugose to ruminate, 38–60 × 27–40 mm
Ecology
Terrestrial or epilithic, in woodland, riverine and montane forests, roadcuttings, but at higher elevations (> 2000 m) in grasslands, moorlands and giant heath zone ; (700–)900–2700(–2900) m
