Abstract

Ligulate and sulfuric-acid containing species of Desmarestia, occurring worldwide from polar to temperate regions, were revised using a multi-genic and polyphasic aproach. Sequence data, gametophyte characteristics and sporophyte morphology support merging a total of 16 taxa into four different species. (1) D. herbacea, containing broad-bladed and richly branched forms, has dioecious gametophytes. The three other species have monoecious gametophytes: (2) D. ligulata which is profusely branched and, except for one sub-species, narrow-bladed, (3) Japanese ligulate Desmarestia, here described as D. japonica sp. nov., which is morphologically similar to D. ligulata but genetically distant from all other ligulate taxa. This entity may have conserved the morphology of early ligulate Desmarestia. (4) D. dudresnayi, including unbranched or little branched broad-bladed taxa. A figure of the holotype of D. dudresnayi, the track of which was lost for decades, was relocated. Taxonomy is complemented by a comparison of ITS and cox1 as potential barcode loci, with cox1 offering good resolution reflecting the species delimitations within the genus Desmarestia.
