030.0000 Family Pteridaceae E.D.M.Kirchn.; Schul-Bot. 109 (1831)
48 genera, ca. 1350 spp. The family has been split extensively in smaller subgroups, but Smith et al. (2006) and PPG-I argue for keeping them together.

Distribution: Mostly American tropics, 1 sp. SW-USA, W-USA, 4-5 spp. Africa/Madagascar. Many invalid names and garden forms (described mostly by Domin) have been omitted. The African species probably belong in other genera.
