Plants in soil [climbing]; rhizome short- to long-creeping to erect, scaly; new growth often ± red. Leaf: of 1 or 2 kinds, fertile, sterile; stipe in ×-section with vascular strands in circle; blade [(simple or 2-pinnate)] deeply pinnately lobed to 1-pinnate, pinnae deeply pinnately lobed or not, hairs generally 0; veins free or netted. Sporangia: sori linear to oblong, along veins parallel to nearest midrib; indusium shaped ± like sorus, opening towards nearest midrib; stalk cells in 2–3 rows; spores elliptic, scar linear.
± 9 genera, ± 250 species: worldwide, especially tropics; several species cultivated. New classification badly needed, in which all genera but Woodwardia are placed under Blechnum or, preferably, ± 25 genera, including ± 10 new ones, are recognized. —Scientific Editors: Alan R. Smith, Thomas J. Rosatti.
