Common name


Climbing fern. Rhizome creeping, rhizome scales linear, blackish-brown. Fronds spaced apart. Stipe and rhachis of an elongated frond function as the climbing stem, from which short secondary rhachises with an opposing pair of pinnae arise, apical bud densely covered with short brown hairs. Pinnae oblong, pinnate, glabrous. Sterile pinnules attenuate, up to 4.5 × 1.3 cm, oblong-lanceolate, base cordate, apex acute to rounded, margins minutely lobed. Fertile pinnules broadly lanceolate to oblong, base square, up to 3.5 × 2.5 cm with numerous protuding fertile lobes, up to 12 mm long; sporangia 10-12 pairs, arranged in 2 rows along the margins.


According to J.E.Burrows (1990), Schelpe (1970) and Roux (2009) not in Zimbabwe, only close to the coast in Mozambique and South Africa.
Differs from L. kerstenii by having glabrous pinnule veins and less divided pinnae (pinnate pinnae).


microphyllum: small-leaved; unclear reference, no parts of the frond are smaller than that of other Lygodium species.


Moist conditions along the margins of evergreen montane and riverine forest.
