According to the results of the 2019 expedition, 38 aquatic and coastal aquatic species of vascular plants from 27 genera and 18 families were identified for the Bikin National Park. Most of the species for this area are presented for the first time. The annotations include information about the species distribution in the territory of the National Park, cited confirming herbarium collections. A brief discussion of the findings is provided. The poor knowledge of the flora of the Bikin River basin, including aquatic plants, and the need for further research are noted.
Biomorphological analysis of weed species of the flora of the Askizsky District are given. Using different approaches, the life forms of 103 species were characterized and the prevalence among weed species of taproot plants with an elongated erect type of shoot was revealed.
Information about a new locality of Melilotoides schischkinii (Vassilcz.) Soják (Fabaceae), a rare endemic to Amur Region, is provided in the article. The habitat of the plant and the status of its population in the region are described. The new locality is remote from the known range of the species, which significantly expands its distribution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
