#Acrostichum

• Acrostichoides — A taxonomic term utilized as a specific epithet in bilingual botanical nomenclature to describe a plant species (most frequently ferns, such as Polystichum acrostichoides) whose fronds, fertile structures, or sori arrangements strikingly resemble morphologically those of the genus 'Acrostichum'.
• Acrostichum — A genus of large, massive, and vibrant ferns belonging to the Pteridaceae family, characterized by their unique structural adaptation to saline environments, being the only ferns that grow natively in mangrove swamps and tropical and subtropical intertidal coastal zones. The genus is distinguished by large, pinnate, leathery (coriaceous) fronds and by the fact that fertile sporangia are not grouped into distinct sori but cover uniformly and densely the entire lower surface of the terminal pinnae.
• Acrostichum aureum — The bilingual scientific name of a specific mangrove fern species (commonly known as the golden leather fern), remarkable for its gigantic stature and extreme salinity tolerance. This halophytic plant presents large, leathery, golden-green fronds, with the fertile pinnae at the apex becoming completely covered underneath by a dense layer of sporangia of an intense golden-brown color, from which the specific epithet 'aureum' is derived.
