Abstract
A new Polypodium hybrid between Polypodium cambricum ssp. macaronesicu m and Polypodium vulgare from Madeira is described as Polypodium x fon t-queri nothossp. encumeadense. This hybrid is triploid (2n = 111) and exhibits mainly univalents but also a number of bivalents during meio sis. By examining isoenzyme profiles and micromorphological characters it was shown that the Madeiran hybrid is different from the triploid hybrid P. x font-queri nothossp. font-queri (= P. cambricum ssp. cambr icum x P. vulgare) occurring in Europe.
