EOL Text
Rhizome short-creeping or erect, sometimes producing tubers, producing stolons that root and form shoots. Stipe not articulated. Fronds tufted, monomorphic, numerous, pinnate; pinnae articulated to the rhachis, closely set, hairy or glabrous. Venation free, ending in a hydathode near the margin. Sori round to oval or linear terminal on the veins, indusium kidney-shaped or linear, entire, opening towards the margin; homosporous.

Terrestrial or epiphytic ferns, bearing.basifix, pseudopeltate or peltate scales on all parts. Rhizome consisting of long creeping or pendent protostelic runners bearing roots and erect dictyostelic radial stems bearing fronds and runners. Fronds not articulated to the rhizome, stipitate, pinnate, often not forming an apical pinna or segment, scales on fronds often inconspicuous or deciduous, catenate hairs sometimes present. Pinnae articulated to the midrib, sessile, often with unequal base, margin usually crenate or serrate, apex rounded to acuminate, venation free, 1 or 2 (or 3) times furcate except in the most basal vein-group, free veins ending before the margin in a hydathode.
Sori terminal on the acroscopic vein-branch (rarely innervated by 2 veins), medial to marginal, indusiate, indusium reniform to lunulate or linear, glabrous. Sporangia long-stalked, glabrous, 0.2-0.24 by 0.15-0.18 mm, with (11 –)13(– 16) indurated annulus cells. Spores 27 –35(– 39) µm , elongate, monolete, brown, variously verrucate to tuberculate or rugose.

Nephrolepis is a genus of about 30 species of ferns in the family Nephrolepidaceae or Lomariopsidaceae (included in Davalliaceae in some classifications). Nephrolepidaceae is part of the eupolypods I clade of the order Polypodiales,[1] in the class Polypodiopsida.[2]
Selected species[edit]
- Nephrolepis biserrata (Sw.) Schott. (syn. Aspidium bisseratum Sw., Aspidium acutum Schkuhr, Nephrolepis acuta (Schkuhr) C.Presl, Polypodium puctulatum Poir)
- Nephrolepis cordifolia (L.) C.Presl (syn. Polypodium cordifolium L., Nephrolepis tuberosa (Bory ex Willd.) C.Presl, Aspidium tuberosum Bory ex Willd.)
- Nephrolepis exaltata (L.) Schott (syn. Polypodium exaltatum L.)
- Nephrolepis multiflora (Roxb.) F.M.Jarret ex C.V.Morton (syn. Davallia multiflora Roxb.)
- Nephrolepis obliterata
- Nephrolepis pectinata (Willd.) Schott (syn. Aspidium pectinatum Willd.)
- Nephrolepis tuberosa
Some species of Nephrolepis are grown as ornamental plants. Nephrolepis exaltata and Nephrolepis obliterata are reported to be good plants for cleaning indoor air.[3]
Some Nephrolepis spp. may prove to be a good source of new antimicrobial chemicals.[4]
