Description:
Genus Description - Epiphytic, occasionally epipetric or terrestrial; rhizome short- to long-creeping; rhizome scales concolorous, brownish, often clathrate, surface glabrous, margin entire; fronds clumped to distant, simple (rarely pinnate, not in ours), monomorphic, sessile to long-stipitate, narrowly linear to elliptic, attenuate at apex and base, articulate on phyllopodia; margin entire, modified; blade thin to usually thick, glabrous; venation areolate with one to usually several or many rows of areoles formed by anastomosing cross-veins from main lateral veins; cross-veins producing two excurrent, simple, free veins, a third excurrent vein sometimes completely bisecting the areole; sori round, exindusiate, non-paraphysate, at ends of free included veins, usually in two rows between main lateral veins; sporangia glabrous; spores bilateral, verrucate with spherical deposits.

Discussion:
Lectotype (chosen by J. Smith, Hist. fil. 95. 1875): Campyloneurum repens (Aublet) Presl [=Polypodium repens Aublet]. Campyloneurum is a segregate genus of Polypodium s.l. of the New World tropics, including approximately 20-25 species. It is characterized by the monomorphic, simple leaves, non-paraphysate sori borne on free included vein tips, and clathrate, glabrous rhizome scales. The genus is greatly in need of monographic work.
