International audience The liverworts of Île Amsterdam are surveyed. On the basis of historical collections and specimens collected on the island in 2006 and 2007 some 29 species and one variety belonging to 18 families have been recorded. This means that in comparison with the last survey of the island’s hepatics, in 2002, the number of taxa has been nearly doubled. Of these, eight taxa are recorded for the first time from the island, namely Kurzia capillaris (Sw.) Grolle subsp. stephanii (Renauld ex Steph.) Pócs, Adelanthus lindenbergianus (Lehm.) Mitt., Syzygiella colorata (Lehm.) K.Feldberg, Vá≈a, Hentschel et J.Heinrichs, S. sonderi (Gottsche) K.Feldberg, Vá≈a, Hentschel et J.Heinrichs, Cephaloziella varians (Gottsche)Steph., Anastrophyllum auritum (Lehm.) Steph., Andrewsianthus marionensis (S.W.Arnell) Grolle and Heterogemma patagonica (Herzog et Grolle) L.Söderstr. et Vá≈a, whilst Aneura subcanaliculata R.M.Schust. is excluded from the island’s hepatic flora. Two taxa, Kurzia capillaris subsp. stephanii and Gymnomitrion subintegrum (S.W.Arnell) Vá≈a, are illustrated, and maps of global distribution are presented for Plagiochila minutula (Hook.f. et Taylor) Gottsche, Lindenb. et Nees, Andrewsianthus marionensis, Heterogemma patagonica, Mnioloma fuscum and Gymnomitrion subintegrum. The liverwort flora is distinctly south-temperate to tropical and these two main distribution patterns consist of12 and eight species, respectively. The subantarctic element is represented by only three species, two species are endemic or near-endemic and five bipolar. Two names, Riccardia insularis Schiffn. and R. novo-amstelodamensis Schiffn., are lectotypified. Cette étude porte sur les hépatiques de l’Île Amsterdam. L’analyse de collections historiques et d’échantillons collectés sur cette île en 2006 et 2007 a révélé la présence de 29 espèces et une variété, appartenant à 18 familles. Ce nombre de taxons est presque le double de celui indiqué dans la dernière étude publiée en 2002. Huit taxa sont cités pour la première ...
