New findings in the flora of Mongolia. Part 2

Abstract

New data on the distribution of 40 species from the families Asteraceae, Cystopteridaceae, Dryopteridaceae, Euphorbiaceae, Poaceae, Rosaceae, and Woodsiaceae in Mongolia are presented in the article. For the first time, Centaurea cyanus, Cystopteris almaatensis, Potentilla × habievii, Potentilla salsa, and Potentilla smirnovii are indicated for the flora of the country. 19 species previously known in the flora of Mongolia are new for its separate botanical and geographical regions. Of these, 7 taxa were found for the first time in the Khuvsgul, 5 – in the Khovd, 4 – in the Gobi Altai and 3 – in the Mongolian Altai regions, 2 each – in the Khangai, Khentei, and Dzungarian Gobi, 1 – in the Middle Khalkha. New locations were registered for 19 rare and endemic species of the study region. There are narrow local national endemics: Potentilla coriacea, P. inopinata, P. laevipes, and P. schmakovii, among them. The findings are divided into three groups in the article. Comments about the range, relationships and main morphological differences are given for each species. Photographic materials of Potentilla salsa made in nature on the territory of Mongolia are demonstrated for the first time.

Notes on Potentilla (Rosaceae) of Altai. 10. New section from Mongolia

“…This finding was published in one of the works of J. Soják, based on the collection of G. N. Ogureeva from the Ikh-Nuru ridge (Soják, 1994). Then, the species was found in other new locations: in the vicinity of the Duru-Nur Lake and the upper reaches of the Bodonchiin-Gol River (Ebel & Rudaya, 2002;Kechaykin et al, 2014); on the eastern macroslope of the Khadzhingin-Nuru ridge and on the Ulan-Daba pass at the headwaters of the Bulgan-Gol River (Kechaykin, 2015); in the vicinity of the Davst-Nur Lake (Kechaykin et al, 2022). These findings presents new localities of P. laevipes found by us on the eastern macroslope of the massif Munkh Khairkhan in the tracts of Nariin-Khag (ALTB: "catalogNumber" SHSHK 1223) and Ikh-Khag (ALTB: "catalogNumber" SHSHK 1259).…”

“…The new annotated checklist of native vascular plants of Mongolia includes 76 Potentilla species (Baasanmunkh et al, 2022). In addition, three new species records of Potentilla were recently found in Mongolia (Kechaykin et al, 2022). Thus, of 79 representatives of the genus Potentilla, 13 are endemic to Mongolia (Baasanmunkh et al, 2021).…”

Distribution of Vascular Plants in Mongolia – III Part

“…A total of 3,041 native taxa belonging to 653 genera and 111 families have been recognized in Mongolia so far (Baasanmunkh et al, 2022a). In addition, six native taxa including Cystopteris almaatensis Kotukhov (Сystopteridaceae), C.A.Mey (Amaranthaceae; Sukhorukov et al, 2022b) and one alien species Centaurea cyanus L. (Asteraceae; Kechaykin et al, 2022) have recently been noted for western Mongolia. Of native taxa, 103 species are considered endemic to Mongolia (Baasanmunkh et al, 2021a(Baasanmunkh et al, , 2022a; however, some of them have been recently found in adjacent countries.…”
