Polypody (Polypodium vulgare) is a perennialfern of the family Polypodiaceae, common to Britain and Europe. It has a creeping, slightly flattened, branched rhizome, which bears numerous red-brown scales. Every year new fronds rise alongside the old ones. The fronds are simple, long- stalked, smooth and pinnately divided with lanceolate segments, rounded at the tip. Clusters of spore cases are arranged in two rows on the undersides of the upper segments, coloured orange at first and then later brown. Research Polypody
