Data on type material of 109 taxa (58 species, 9 subspecies, 28 varieties, 6 forms and 8 lususes) of the genus Viola L. (Violaceae Batsch) kept in the Herbarium of the Komarov Botanical Institute (LE) are summarized in the paper. Information is given about types of both the names accepted in the «Vascular plants of the Soviet Far East» and «Flora of Siberia» and the names treated as synonyms, and some of forms and varieties, not refered in them, but described from Siberia and the Russian Far East. Lectotypes for 29 names in the genus Viola are selected. This work was carried out in the framework of the study "Types of taxa of vascular plants of Siberia and the Far East, stored in the Herbarium of the Komarov Botanical Institute RAS (LE)". The names of taxa are arranged alphabetically. For each taxon is given: 1) Latin name with reference to the publication of its original description; 2) the category of the type, and in the case of a lectotype- A n indication of where and by whom it is selected; 3) the region from which the specimen was collected (zoning is given in three major regions: Western Siberia, Eastern Siberia, the Russian Far East, and within them-in accordance with the administrative division); 4) a formal citation of the label of the authentic specimen: The location, date of collection, phenophase, number, name of the collector, if necessary, information about the collection, and the name indicated on the label; 5) an data from the protologue; 6) the necessary notes. The typifcation of names took into account the recommendations of the international code of Botanical nomenclature (McNeill et al., 2012). Four taxa (2 species, a variety, and a lusus), material on which was not found in LE are also mentioned.
