Lepisorus

Lepisorus is a genus of ferns belonging to the family Polypodiaceae. These ferns are primarily epiphytic or lithophytic, meaning they grow on other plants or rocks, respectively, rather than in soil. They are native to Asia, with a high concentration of species found in East and Southeast Asia.

Characteristics: Lepisorus ferns typically have creeping rhizomes, from which simple, undivided fronds arise. The fronds can vary in size and shape depending on the species. A key characteristic of the genus is the presence of sori, the structures containing spores, which are arranged in a distinct pattern on the underside of the fronds. The sori are generally round or oval and are often sunken into the leaf tissue.

Classification: The classification of Lepisorus has been subject to revision based on molecular and morphological data. Historically, it was often considered a larger genus, but some species have been moved to other genera within the Polypodiaceae family.

Ecology: Lepisorus ferns are adapted to a range of habitats, from humid forests to drier, more exposed rock faces. They are often found in areas with moderate rainfall and high humidity. As epiphytes, they benefit from the moisture and nutrients that accumulate on the surfaces of their host plants.

Cultivation: Some species of Lepisorus are cultivated as ornamental plants, prized for their attractive foliage and relatively easy care. They typically require well-draining substrates and moderate light conditions.
