To the diagnosis of species of the genus Trollius L. (Ranunculaceae) of the Altai mountain country
УДК 582.675.1+581.9
Abstract
The article provides information about the taxonomic composition of the genus Trollius in the Altaimountainous country. 3 species are revealed: T. asiaticus, T. altaicus, T. dschungaricus, for which the systematic positionis indicated, the nomenclature and morphological descriptions are given, the geographical distribution is characterized.Along with the known diagnostic features of these species, new, previously unused features of the structure of theirvegetative and generative organs are proposed: the ratio of the length and width of the lobes and segments of the leafblades, the outlines of their edges (the degree of dismemberment, the shape of the teeth and recesses), the number of veinsof the petals below the nectar fossa and above it.
