Distribution maps of Bryophytes in Britain and Ireland

Abstract

Eight epithets of Rigodium (R. araucarieti C. Müll., R. argentinicum C. Müll., R. brachypodium (C. Müll.) Par., R. nano-fasciculatum C. Müll. ex Thér., R. pendulum Herz. &; Thér., R. pseudo-thuidium Dus., R. solutum (Tayl.) Par., and R. tamarix C. Müll), lectotypified here, are listed with their nomenclature and pertinent details involving the careful identification of type specimens and original material. For Rigodium solutum (Tayl.) Par., a specimen from Taylor's original herbarium may likely be the holotype but had not been indicated as such by Taylor, the original author. A conservative approach for this situation is taken here by designating this specimen as a lectotype.
