Rhizome not white waxy, creeping, roots present but absent in L. axillaris. Rhizome scales pseudopeltate or peltate, clathrate or subclathrate, sometimes with a central tuft of hairs. Fronds monomorphic to strongly dimorphic, stipitate, simple or pinnatifid, thin-herbaceous to subcoriaceous. Venation: veins branching less than halfway to or near the margin, or seemingly close to the costa, connecting veins ana-or catadromous; included veins amply anastomosing; free veinlets excurrent and recurrent, recurrent in marginal areoles. Sori separate, in a row between the veins, or in wide fertile fronds forming transverse coenosori, sometimes broadened into an acrostichoid patch; in narrow fertile fronds longitudinal, narrow and linear coenosori near the margin of these fronds.
Terrestrial or lithophytic ferns, sometimes climbing; rhizome short-to long-creeping; scales on rhizome and stipe base, small, minutely latticed, peltate; fronds closely to distantly spaced along rhizome. Stipe slightly grooved above; vascular strand broadly U-shaped in section. Fronds simple, entire, articulate on rhizome, dimorphic. Sterile frond oblong to elliptic, the base narrowly decurrent on stipe; midvein and lateral veins pinnate, with anastomosing veinlets between, forming areolae. Fertile frond reduced, very narrow; sporangia acrostichoid, densely covering lamina beneath; indusium and paraphyses absent.
Fronds c. 30 cm long; rock-plants or epiphytes
