Intermediate Polypody (Polypodium interjectum) is a perennial fern native to the United Kingdom, belonging to the Polypodiaceae family. It is commonly found in woodland habitats, particularly in damp and shaded areas such as woodland floors, rock crevices, and mossy banks.

Intermediate Polypody thrives in nutrient-rich, moist, and well-drained soils with high organic matter content. It prefers habitats with partial to full shade, often growing on the base of trees or in the shelter of rocks and boulders.

As a fern, Intermediate Polypody reproduces via spores rather than seeds. It forms clusters of fronds with distinctive lance-shaped leaflets, which arise from a creeping rhizome. These fronds can persist throughout the year, providing habitat and shelter for small invertebrates.

Predators of Intermediate Polypody primarily include herbivores such as snails and slugs, which may feed on its fronds. However, its tough and leathery foliage often provides some protection from extensive grazing.

Culturally, Intermediate Polypody does not hold significant symbolic or traditional references in the UK. However, it is valued for its ornamental qualities and is sometimes cultivated in shaded gardens or woodland landscapes.

An interesting fact about Intermediate Polypody is its ability to colonise harsh and rocky environments, where it often thrives in crevices and fissures. It is also known for its ability to tolerate air pollution, making it a resilient species in urban environments. Additionally, the spores of Intermediate Polypody are dispersed by wind, allowing it to spread and colonise new areas.
