Blechnaceae Habit: 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. Genera In Family: 24 genera, +- 250 species: worldwide, especially tropics; several species cultivated. Note: Until recently, most species usually treated in an extremely morphologically heterogeneous Blechnum, with some species more closely related to other genera (such as Brainea, Doodia, Sadleria) than to other species of Blechnum.
