Leaf: stipe ×-section at base with 2 crescent-shaped vascular strands fusing into 1 U-shaped strand distally; blade 1- pinnate, generally with needle-like, clear hairs on axes and/or between veins; rachis, costae generally grooved adaxially except between axes; veins free or in regular, net-like pattern.
Sporangia: sori on veins, generally round; indusia reniform or round- reniform ; stalk cells in 3 rows; spores generally elliptic, scar generally linear.
1 genus (5–32 genera), ± 1000 species: worldwide, especially tropics; several cultivated. —Scientific Editors: Alan R. Smith, Thomas J. Rosatti.
