Abstract

Based on the authors’ fieldwork in 1976-2022 and herbarium funds from the river Chulyshman, stored in the Central Chernozem Reserve, the second part of the information (Magnoliophyta: Liliopsida, including the Poaceae Barnhart family) is given on new and rare species of vascular plants for this territory.

For the modern territory of the Altai Reserve, 5 additional species are indicated (Dactylorhiza incarnata, Achnatherum splendens, Leymus ovatus, L. paboanus, L. tuvinicus), for the forest-steppe valley of Chulyshman -7 species (Lemna trisulca, Achnatherum confusum, Catabrosa aquatica, Leymus chinensis, L. pubescens, Poa trivialis, Stipa kirghisorum). 2 species (Asparagus tamariscinus, Stipa kirghisorum) are recommended for inclusion to the Red Data Book of the Altai Republic.
