Abstract
Information on new characters, that were not previously used for the Trollius species identification is presented: consistence and degree of dissection of blade, type of margin, shape of teeth, number of petal veins, shape of nectarostigma, and morphological characters of fruits - type of the pericarp surface. The quantitative and qualitative morphological characters of the species are indicated: number of sepals and petals, distance from the petal base to the nectarostigma, length of the follicle and persistent style, as well as its shape and location. An identification key is proposed, which has been developed taking into account the suggested characters. A sinopsis of the genus Trollius (Ranunculaceae) of the Altai Mountain Country, including 3 species belonging to 2 sections is given. The synopsis includes nomenclature quotations, information on type specimens, distribution in the region, and general distribution for each species.

Information on new characters, that were not previously used for the Trollius species identification is presented: consistence and degree of dissection of blade, type of margin, shape of teeth, number of petal veins, shape of nectarostigma, and morphological characters of fruits – type of the pericarp surface
Trollius altaicus is characterized by short teeth, arcuate-convex along the edge, and acute or slightly obtuse at the apex
Trollius altaicus has the longest persistent style, which distinguishes it from two other species
Summary
Information on new characters, that were not previously used for the Trollius species identification is presented: consistence and degree of dissection of blade, type of margin, shape of teeth, number of petal veins, shape of nectarostigma, and morphological characters of fruits – type of the pericarp surface. A sinopsis of the genus Trollius (Ranunculaceae) of the Altai Mountain Country, including 3 species belonging to 2 sections is given. The aim of this work was to study the taxonomy and characters of the Trollius species in the flora of the Altai Mountain Country. We identified diagnostic morphological characters of the Trollius species of the Altai Mountain Country, searched for new charactes for the identification of taxa, compiled the key for species identification, and analyzed the distribution of Trollius species in the AMC
