Comments on the article “Set of additions and changes to Check-list of the flora for the Republic of Buryatia between 2001 to 2020” about the flora of the Baikalsky Reserve

This article analyzes the materials of the “Set of additions and changes to the check-list of the flora of the Republic of Buryatia from 2001 to 2020”. Corrections and comments are given on 50 species of higher vascular plants, both erroneously cited as novelties, and, on the contrary, absent from the original publication, regarding the territory of the Baikalsky State Nature Reserve and its buffer zone. Two taxa amongst omitted in the source material are included in the Red Data Book of the Russian Federation (Aconitum paskoi subsp. arcto-alpinum and Asplenium sajanense), and 10 species are alien for the flora of Buryatia (Achillea ptarmica, Alchemilla baltica, Atriplex sagittata, Carthamus tinctorius, Centaurea phrygia, Convolvulus inflata, Epilobium tetragonum, Persicaria maculosa, Setaria pumila, Sorghum halepense). Several plant species actually were firstly recorded for Buryatia earlier than the period from 2001 to 2020 or have been already known for this territory much earlier; Rhynchospora alba is one of such species, and it is included in the all the editions of the Red Data Books of the Republic of Buryatia. In some cases of references to early indications and herbarium collections, modern ideas about the taxonomy of groups and ranges of species are considered for clarification.
