Syntrichia christophei Ochyra et R.H. Zander is new to science from Îles Kerguelen in the Subantarctic. The species is described and illustrated and its affinities are discussed. It is closely related to S. saxicola (Cardot) R.H. Zander but it is easily distinguished by its larger leaf size, larger distal laminal cells, longer awn at the leaf apex, and larger capsules and spores. Syntrichia christophei is endemic to Îles Kerguelen, a highly isolated archipelago in the Southern Ocean, and evolutionary interpretation of its origin is presented.
