Pyrrosia serpens is a creeping, evergreen fern with elongated, thick and leathery leaves that often adopt a serpentine growth pattern, hinting at its name. Thriving in tropical and subtropical forests, it clings tenaciously to tree trunks and branches, benefiting from the humid and sheltered environment. Its foliage, a muted green, is punctuated by spore-containing structures underscoring its fern heritage, while its resilience allows it to prosper in the dappled light under the forest canopy.
