Abstract(s)
A brief survey is made of the species and hybrids of ferns of the genus Dryopteris on Pico Island. The richness of the island is remarkable, containing as it does 5 species and, so far, 5 hybrids, despite the fact that Central-European, boreal and alpine species are absent as would be expected. Many of the species have been confused in the past and it is only since the recent work of Gibby, Reichstein, Fraser-Jenkins and others that their systematics and the taxonomic distinction between species have been clearly understood. Most of the species are relevant to the European mainland flora, including three ancient ancestral diploid species which have been preserved on the Azores, one of them probably nowhere else.
