Rhizome shortly creeping, thick, c. 8 mm in diameter, embedded in a thick felt of roots; rhizome scales black, peltate, lanceolate, entire, acuminate, up to 4 mm long. Fronds closely spaced, apparently tufted, rigid, glabrous, coriaceous. Stipe short to absent. Lamina very narrowly elliptic-oblong, simple, margins entire to irregularly wavy, apex rounded to tapering to a point, gradually decrescent to a broadly or narrowly winged base, midrib raised on both sides; venation obscure, anastomising with included veinlets. Sori circular, minute, ± 1 mm in diameter, distributed irregularly on the undersurface of the fronds.
Notes: Can be recognized by its large simple fronds and the minute sori that are scattered over the undersurface of the lamina.
Derivation of specific name: punctatum: dotted or marked with spots, referring to the minute sori which are irregularly distributed over the underside of the fertile fronds.
Habitat: Epiphytic, lithophytic or terrestrial in seasonally dry to moist evergreen forest.
Altitude range: (metres) 100 - 1000 m
