Description:Genus Description - Terrestrial, epiphytic, or occasionally epipetric; fronds medium-sized to large, clumped, not articulate; rhizome erect, woody, scaly at apex, generally with numerous above-ground stolons producing young plants along their length, in some species underground stolons tuber-producing; stipe short, scaly, stramineous to brown; blade once-pinnate; pinnae articulate to rachis, thin to coriaceous, often with lime dots on upper surface; veins free, forking; sori round, terminal on veins, indusiate, indusia round, reniform or lunate; spores bilateral.
Discussion:Lectotype: Uncertain, regarded by J. Smith (Hist. fil. 226. 1875) and Tryon (Contr. Gray Herb. 194: 225. 1964) as Nephrolepis exaltata (Linnaeus) Schott, but by Christensen (Index filic, xxvii. 1906) as N. biserrata (Swartz) Schott.
Nephrolepis is a genus of 25-30 species of tropical regions of the world, seven native in America, one species naturalized from Asia. Several species are widely cultivated. The genus is distinguished by stolons, linear, once-pinnate fronds, and articulate pinnae.
