Jointed fern
Jointed fern is a delicate, shade-loving fern often found clinging to mossy rocks and tree trunks in humid forest environments. Its presence indicates a rich, moist ecological niche, allowing its thin, wiry fronds to thrive. Those fronds, typically light green and finely divided, uniquely grow from rhizomes that creep across the surfaces jointed fern inhabits, showing the plant's adaptation to gaining moisture and nutrients in competition with larger flora.
