FLORA OF ICELAND elements: Polypodium vulgare, Common Polypody

Polypodium vulgare; The Common Polypody is a crawling fern, sending leaves (frond's) from rhizomes. These frond's are 10 to 20 cm long. The first-order leaflets have rather roundish tips and smooth margins. On the bottom-side of the leaves are the sori (spore-forming organs) which are round-shaped and lacking a covering-bract known as an indusium. It is found mainly along the southern coast of Iceland and also in the west. It is much rarer in the north and north-east. It generally grows on cliffs and rock crevices. The Icelandic name for this species is Kòldugrass.
It is a member of the fern-family: Polypodiaceae (Polypody family)
