description_en: Genus of about 12 species of deciduous, terrestrial ferns found in damp places and watersides in all continents except Australasia. Broadly lance-shaped to triangular-ovate or ovate, pinnate, 2-pinnate, or 2-pinnatifid sterile fronds arise from large, erect rhizomes and turn yellow or golden brown in autumn. Distinctive, partially or wholly fertile fronds produce branched clusters of spherical greenish sporangia, which turn rust-brown or blackish on reduced pinnae. Grow in a damp border, or at the margins of a pond or stream.
