The genus Pyrrosia belongs to the fern family, characterized by its unbranched fronds, wavy edges, and distinctive scales on the stem and underside. While less common than other fern genera, Pyrrosia can be easily identified by the unique morphology of its fronds. Synonyms for Pyrrosia include Variolospora, Cibotium, and Drymotaenium. These names have been used historically, but Pyrrosia is the most commonly accepted nomenclature. Pyrrosia species are found primarily in Asia and the Pacific Islands, growing in rocky habitats such as cliffs, crevices, and boulders. Some species have been used in traditional medicinal practices for their anti-inflammatory and antitumor properties.
