The five known species are Taraxacum gallicum, T. handelii, T. kraettlii, T. mazzettii and T. melzerianum. From 2004 up to 2014 these localities have been visited. Detailed examinations of many collections make it possible to add characteristics and precise the descriptions and correct mistakes, eliminate ambiguities and fill gaps in the original descriptions. Numerous photos, drawings and a new determination key will make the access to the section Borealia easier. A new species of section Borealia, T. cimae-gallinae, from the mountain H{\"u}hnerspiel near Sterzing (Italy, South Tyrol) is described. The habitats of the Borealia in the alpine level are mostly gravel floors on wind-swept ridges or on summit levelings. The environment of Borealia-species is threatened by ski tourism or by the changes from global warming.}, subject = {Pflanzen}, language = {de} }
