New findings of alien plants in the Republic of Altai.

Abstract

In 2017, the authors of this report continued to study the species composition of alien plants in the Republic of Altai, as well as the distribution patterns of both rare and more common alien species (including invasive plants). Routes that covered 8 out of 10 administrative regions of the Republic of Altai were laid along the main motor roads. Additionally, the territories of several settlements (including the administrative center of the Republic, the city of Gorno-Altaisk) were investigated with varying degrees of detail. Moreover, some crop fields and abandoned agricultural fields of the different age were surveyed. As a result of the researches in the Republic of Altai, 6 new for this territory alien plant species were identified. These are Celosia argentea, Chrysaspis campestris, Eriochloa villosa, Lolium perenne, Phalacroloma annuum, and Symphyotrichum novi-belgii. Also information on the spread of 21 rare plant species (including one interspecific hybrid) is supplemented. The article contains an annotated list of all these species, indicating their habitats and exact geographical coordinates of the collection sites. The collected herbarium specimens are stored in NS, TK and KUZ; doublets are transferred to ALTB.
