The Sinking of Another Tristan da Cunha Moss Endemic and Its Phytogeographical Consequences

Abstract

<p>The original material of <em>Isopterygium tristaniense </em>Dixon, an endemic species of the Tristan da Cunha archipelago in the central South Atlantic Ocean, is taxonomically evaluated and some details of its morphology are illustrated. The species is found to be conspecific with the Holarctic <em>Pseudotaxiphyllum elegans </em>(Brid.) Z.Iwats. and it is the third record of the species in the Southern Hemisphere. The global distribution of this species is reviewed and the distribution patterns of the South Atlantic mosses are briefly discussed.</p>

Recent Developments in Taxonomy and Phylogeny of Plants

“…Four papers focus on taxonomy and phytogeography of mosses in different parts of the world. Ochyra and Plášek (2020) described Isopterygium tristaniense (Hypnaceae), an endemic species of the Tristan da Cunha archipelago in the central South Atlantic Ocean, which was found to be conspecific with the Holarctic Pseudotaxiphyllum elegans. The global distribution of this species is reviewed and, the distribution patterns are discussed.…”
