Abstract

The paper presents data on eight new taxa for the flora of Buryatia (Ambrosia artemisiifolia, Lapsana communis, Leonurus quinquelobatus, Linum usitatissimum, Lolium arundinaceum, Plantago major subsp. intermedia, Trifolium aureum, Typha angustifolia), five new taxa for the Khamar-Daban ridge (Carduus nutans subsp. leiophyllus, Cirsium pendulum, Lotus corniculatus s. str., Peucedanum vaginatum, Scleranthus annuus), as well as new localities for the twenty five rare native plant species (Artemisia desertorum, Astragalus davuricus, Chenopodium acuminatum, Epipogium aphyllum, Monotropa hypopitys, Paeonia anomala, Saussurea amara, Utricularia intermedia), alien plant species (Campanula patula, Centaurea phrygia, Helianthus tuberosus, Hippophaё rhamnoides, Hordeum jubatum, Juncus compressus, Lathyrus tuberosus, Lolium multiflorum, Lupinus polyphyllus, Pastinaca sativa, Persicaria maculosa, Setaria pumila, Silene chalcedonica, Sinapis alba, Sisymbrium volgense, Veronica beccabunga), and a hybrid species (Fragaria × ananassa) in the Southern Baikal region. For a group of apophyte plant species (Oxybasis glauca, Puccinellia hauptiana), alien plant species (Avena fatua, Echinochloa crusgalli, Epilobium adenocaulon, Epilobium pseudorubescens, Erigeron canadensis, Galium mollugo, Juncus tenuis, Matricaria discoidea, Melilotus albus, Melilotus officinalis, Rumex pseudonatronatus, Scorzonerioides autumnalis, Senecio viscosus, Senecio vulgaris, Trifolium hybridum, Trifolium spadiceum, Tripleurospermum inodorum, Tussilago farfara), a subspecies (Panicum miliaceumsubsp. ruderale) and a hybrid species (Medicago × varia) that have become widespread in the Southern Baikal region, the distribution maps are given for the Baikal State Nature Reserve, its buffer zone and surroundings.
