Low epiphyte; rhizome wide-creeping and branching, thin, glabrous or nearly so. Fronds spaced 0.5–7 cm apart; stipe 0.4–7 cm long, narrowly winged in upper part, glabrous; lamina narrowly ovate to lanceolate in outline, 1.5–11x1–3 cm, rather irregularly 2–3-pinnatifid; pinnae somewhat acroscopically developed; pinnae lobes up to 15 per pinna, to 1.5 mm wide, obtuse to shallowly emarginate, margin entire; entire surface glabrous. Sori mainly on inside acroscopic lobes in upper part of lamina, 1–2 per lobe apex; indusium ovate to obtriangular, soral valves entire, 1.1–2 mm in diameter.

Notes
USES. None recorded. CONSERVATION Widespread; least concern.. Kornaś in B.J.B.B. 54: 15, t. 1, 2 (1984) lists his own collection, Morogoro District: Uluguru Mts, Bondwa Peak, Feb. 1972, Kornaś 1208C (KRA, not seen) as Hymenophyllum inaequale (Poir.) Desv. in Mém. Soc. Linn. Paris 6: 335 (1827). Type: Madagascar, collector unclear, ‘herb. DC and du Petit Thouars’. Basionym: Trichomanes inaequale Poir. in Lam., Encycl. Méth., Bot. 8: 74 (1808); Mecodium inaequale (Poir.) Copel. in Philipp. J. Sci. 67: 96 (1938). The distribution of this taxon is Madagascar, Mascarene Islands, Comoros, Seychelles. Kornaś describes the differences with H. kuhnii but does not mention other taxa. As I have not seen the specimen I hesitate to make a decision about it but according to Kornaś’ description the only differences with H. capense are the wingless stipe and wider lamina. Schlieben 3138! from Tanzania, Uluguru Mts NW, Dec. 1932 keys out here but is much shorter than H. capense. Fronds are at most 20 x 12 mm with simple, bifid or at most 4-lobed pinnae. Sori are 1-1.2 mm in diameter. I am uncertain about its status.
