Ochyra, R., Váňa, J., Smith, V. R. & Cykowska-Marzencka, B. 2014. Seven liverwort species new or confirmed from subantarctic Prince Edward Island. — Herzogia 27: 397–407.
Seven species of liverwort are reported from subantarctic Prince Edward Island in the Prince Edward Islands archipelago. Five of these, Hygrolembidium ventrosum, Clasmatocolea rigens, Anastrophyllum auritum, Andrewsianthus marionensis and Tylimanthus viridis, are new additions and the occurrence of Marchantia berteroana and Clasmatocolea vermicularis is confirmed for the island's flora. Global distribution maps for Hygrolembidium ventrosum, Clasmatocolea rigens and Tylimanthus viridis are provided. Considering these records, the liverwort flora of the Prince Edward Island now totals 42 species and is much richer in the number of species than that of the much larger Îles Kerguelen.
