Abstract
A revision of Taraxacum sect. Naevosa, previously neglected in Russia, is presented. Two species are recognized in Russia: T. naevosum and T. kolaense, both occurring in Murmansk Region, within Rybachiy and Sredniy Peninsulas. Purple spots more or less evenly covering the leaf surface in the flowering time are a characteristic and easily recognizable feature of this section, which is yet unknown in other Taraxacum of Russia (at least in its European part). Taraxacum naevosum is reported from Russia for the first time, whereas T. kolaense has been reported previously, but only after the type collection dated back to 1909, and it was not represented in Russian herbarium collections. The determination key, morphological descriptions and list of herbarium specimens of all taxa are provided, conservation issues and notes about possible records of further related species are discussed.
