Information
Epiphytic or sometimes on rocks. Rhizome widely creeping with reddish brown hairy roots and fronds spaced up to 5 cm apart; scales dark grey-brown, narrowly lanceolate, acuminate, pseudoserrate, clathrate. Fronds simple, very rarely forked, narrowly elliptic, 5.5–35 cm long and up to 3.2 cm wide, entire, irregularly sinuate or rarely with some median lobes; midrib and venation immersed; stipe straw-coloured to purplish brown, up to 3 cm long, continuous with phyllopodium and scales extending up the base of the stipes. Sori up to 2.3 cm long, 2.5 mm wide, linear-oblong, set at about 15° to the midrib and usually but not always overlapping by less than 1/4 of their length (rarely by up to 1/2), quite frequently not overlapping at all.

Notes
M.G. Price in his exhaustive study of this genus has separated L. abyssinica from L. lanceolata, the latter not occurring on the mainland of Africa. The main distinguishing features separating the two are as follows – in the former the phyllopodium is continuous with the stipe, there being no discernible boundary, and scales extend up the base of the stipe a short way – in the latter the stipe is non-functionally articulate to the phyllopodium with a clear boundary and the scales are restricted to the phyllopodium.
