Marsileaceae Mirb.

Description

Sporocarps one or more at or near base of stipes, hairy, firm, about globose, containing the sori, rupturing by 1 or 4 slits. Sori 4 or more, bearing sporangia on a receptacle; megasporangia below, the large megaspore imbedded in a thick layer of mucilage; microsporangia above, with numerous minute microspores. Spores tetrahedral. Rhizome far-creeping, branching, solenostelic; fronds linear, or 2-4-foliate, in 2 rows. Subaquatic to aquatic ferns of 3 genera.

Marsileaceae Mirb.

Description

Mostly aquatic ferns with creeping, branching rhizomes. Lvs arising at nodes, linear or with 2-4 ± obtriangular segments terminating a long stalk. Sporangia aggregated into sori, each containing both micro- and megasporangia, protected by indusia, and all enclosed in a hard sporocarp (modified lamina); annulus 0. Heterosporus, producing 1 megaspore per megasporangium and many microspores per microsporangium; spores lacking chlorophyll.
