Commonly known as the tongue fern, is a species of epiphytic fern belonging to the family Polypodiaceae. Native to East Asia, including China and Japan, it is known for its distinctive tongue-shaped leaves. The fronds are leathery and tongue-like, attached to creeping rhizomes.
Typically grown as a houseplant or in shaded gardens, Pyrrosia lingua is appreciated for its ornamental value and ease of care. It thrives in low to medium light conditions and well-draining soil. As an epiphytic fern, it can be grown on tree trunks or mounted on surfaces, mimicking its natural habitat in tropical and subtropical regions.
