Abstract

Stem creeping, small and slender, often branched, nearly protostelic or solenostelic, not indurated, usually bearing trichomes; floating leaves ca. 0.5–2.5 cm long, not circinate in the bud, petiolate leaves without stipules; sori borne on the lobe of a leaf or on a branched leaf, indusiate, with the sporangia stalked, not annulate, the sori either megasporangiate or microsporangiate; heterosporous, spores without chlorophyll. Megagametophyte and microgametophyte minute, partly protruding from the spore wall.
