Information
Epiphytic, on rocks or buildings or rarely terrestrial. Rhizome long-creeping, 1.2–2.1 mm thick with fronds borne at intervals of 1–2 cm and with pale brown to grey linear-lanceolate usually distinctly ciliate scales 1–8 mm long, 0.3–1.3 mm wide. Fronds indistinctly to distinctly stipitate, ± coriaceous, moderately to distinctly dimorphic; stipes 0.5–5(–9) cm long; lamina linear to lanceolate or narrowly elliptic, 2–31 cm long, 0.3–3.5(–4.3) cm wide, rounded to acute at the apex, cuneate, narrowly cuneate or attenuate at the base, the margins often narrowly reflexed, thinly stellate-pubescent to ± glabrous above, densely tomentose beneath with pale brown to grey stellate hairs 0.2–1.2 mm wide with short flattened or narrow arms, but often soon glabrescent or ± glabrous. Sori mostly apical or all over the lamina, closely packed in a ± sharply defined patch, eventually individually distinct and emergent from the tomentum.

Notes
Hovenkamp gives a great deal of extra synonymy and bibliography and discusses the variation shown by the species (pp. 197–198); he gives descriptions of 7 informal infraspecific taxa and the African material falls under “spissa”. Since the East African material appears genuinely conspecific with the typical Indian and Ceyloneseplants no further discussion is needed but certainly some material from east of India does appear rather different. The earliest specimen from East Africa appears to be one collected at Morogoro by Archbishop Leroy in 1888.
