Dicranodontium Schwabei (Bryophyta, Dicranaceae) Revisited: Some Taxonomic and Nomenclatural Considerations

Open access


Dicranodontium schwabei Thér. & Herzog, a poorly known species from Western Patagonia in Chile, is briefly assessed taxonomically. Some morphological and anatomical details of the species are illustrated and the problems associated with the typification of its name are discussed. The conspecificity of this species and Chorisodontium aciphyllum (Hook.f. & Wilson) Broth. is confirmed and the geographical distribution and ecology of the latter species is briefly reviewed.
