Acrostichum is a genus of tropical ferns belonging to the family Pteridaceae. These ferns are characterized by their sporangia, which are spore-producing structures that cover the entire underside of the frond. Acrostichum species are typically found in brackish and saline swamps in tropical coastal areas worldwide. They are large, leathery-leaved ferns. The genus name itself comes from Greek, referencing the arrangement of spores on the leaflets.12
