Trees; rhizome modified as a trunk, generally short-creeping, ascending, or erect; scales especially on trunk tip, stipe bases, small to generally large, generally uniformly tan to brown, among hairs or not. Leaf: generally tufted or short-spaced, 1–1.5 m, generally ± alike; stipe firm, not easily crushed, base darker or not; blade 2-pinnate [(simple)], ± glabrous or with hairs, hair-like scales, or gland-tipped hairs on axes, veins generally free (netted); axes generally grooved adaxially. Sporangia: sori ± spheric; indusia 0 [saucer- or cup-like to spheric]; spores variously ornamented, scar 3-rayed.
5–6 genera, ± 600 species: worldwide, generally tropics. [Lehnert 2011 Brittonia 63:11–45] Some recognize only 1 genus in family. —Scientific Editor: Alan R. Smith.
Trunk generally 1, often thickened by fibrous mass of adventitious roots basally, generally with distinct, ± round or oblong leaf scars. Leaf: generally 2-pinnate, stipe scales of various sizes, not intergrading with hairs or black spines, cells of ± 1 size, orientation (not clearly smaller, of different orientation on margin). Sporangia: sori in 1 row on each side of pinnule lobe midvein.
± 100 species: ± worldwide, southern temperate, tropics (except Africa). (Greek: sphere, fern, for sori) [Clark & Summers 2013 Madroño: in press]
