Syzygiella setulosa Stephani (1902a: 469) View in CoL is a very common species, especially in the Bolivian Andes. The species is morphologically quite variable and includes several morphological extremes. Already Stephani (1916) described four binomials from Bolivia which are considered to be synonyms of Syzygiella setulosa View in CoL , i.e. Jamesoniella rotundifolia Stephani (1916: 185) View in CoL , Plagiochila connatistipula Stephani (1916: 194) , Plagiochila hariotii Stephani (1916: 200) and Plagiochila purpurea Stephani (1916: 208) ( Inoue 1966) . According to our revision, Syzygiella inouei Grolle (1968: 354) View in CoL represents an extreme, intensively reddish modification of Syzygiella setulosa View in CoL with large papillae on the cell surface. Morphologically similar populations are known from high altitudes of Bolivia, Peru and Ecuador. Intense red color as well as dense and sometimes high papillae on the cell surface correspond with extreme ecological conditions (water, light) above the timberline. These populations resemble Syzygiella rubricaulis ( Nees 1833: 344) Stephani (1902a: 468) View in CoL but differ in oppositely inserted, dorsally connate, orbiculate leaves.
