Polypodium macaronesicum

A creeping polypody of the Atlantic islands (Azores, Madeira, Canaries) that grows on mossy rocks, walls and tree trunks. Like its Mediterranean relatives it is a winter-green fern: fronds appear with the autumn rains and often shrivel during the dry summer, which growers should respect.
