The Munkhkhairkhan mountain area is a unique highland ecosystem with a diverse regional alpine flora. This mountain habitat is located at the overlap of different floristic regions: on its western side Kazakhstan–Turan flora is dominating, and on the eastern side East Asian flora is observed. It is known that the whole area has a large number of endemics and rare plant species, because of its specific, harsh habitat conditions. Therefore, the flora of different habitats in the Munkhkhairkhan mountain needs to be investigated and properly protected. Munkhkhairkhan National Park has been founded in 2006, and our survey concentrated on the protected area as well as the surrounding areas of the mountains. All recorded species in this study were based on the collected voucher specimens. Conservation status for remarkable species was also reviewed based on the literature. As a result, we recorded 40 families, 150 genera, and 267 species of vascular plants, including four endemic and 34 subendemic species and 15 species' new distribution notes. Around the Munkhkhairkhan mountain, 16 very rare, 21 rare, eight endangered, and two near threatened species are growing, indicating the high conservation value of this area and the necessity for research.

The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.

In this study, we investigated four aquatic plants, namely Nuphar pumila (Timm) DC. and Nymphaeacandida C.Presl in Nympaeaceae as well as Menyanthes trifoliata L. and Nymphoides peltata (S.G. Gmel.)Kuntze in Menyanthaceae from Mongolia based on field surveys, herbariums, and scientific literature. Additionally In addition, we carefully examined for Nymphaea tetragona Georgi, which was previouslyrecorded in several lakes, Khar-Us, Khar, Buuntsagaan, and Tsetsegt as well as the Ider river in Mongolia. Because we did not find N. tetragona in the field and because it is difficult to identify from herbariumspecimens, we believe it has been misidentified at the Khar-Us, Khar, and Tsetsegt lakes to date. Moresurveys are needed to document its presence. Finally, we provide detailed distribution maps, photo illustrations,and taxonomic notes of four species.

Field surveys were conducted in the northern part of Mongolia in 2017 and 2018. Vascular plants floristicdata are based on collections from the study area, and more than 800 new collections are made in thisstudy. In total, 289 taxa (8 subspecies and 6 variates) were identified, representing 173 genera from 60families of vascular plants. The families most diverse in species were Rosaceae with 28 taxa, followed byRanunculaceae (25 taxa), Asteraceae (19 taxa), and Fabaceae (19 taxa). The largest genera were Salix with11 species, followed by Viola (9 species) and Carex (9 species). Thirty-seven taxa are newly recorded forMongolian Dauria (8), Khangai (8), Khentei (4) and Khuvsgul (17) regions. Several threatened specieswere found in the field area. We provide photographs and distribution maps for species of Cypripedium(C. calceolus L., C. guttatum Sw., C. macranthos Sw., and C. ventricosum Sw.). In addition, Campanula cervicariawas newly recorded for the flora of Mongolia.

Saussurea dorogostaiskii Palib. (Asteraceae) is a critically endangered medicinal plant in Mongolia and Russia. We studied the genetic variation of S. dorogostaiskii from three mountains of northern Mongolia. The genetic profile was assessed in 70 individuals from eight populations using five inter-simple sequence repeat markers, producing 53 loci with 96.4% polymorphism across all bands. Shannon’s index (I) and Nei’s gene diversity (H) value at the species level of S. dorogostaiskii are 0.25 and 0.17, respectively. An AMOVA showed high genetic variation among the populations (22% of populations and 32% of mountains), consistent with the high genetic differentiation (GST = 0.49) and low gene flow (Nm = 0.51) in S. dorogostaiskii populations. Eight populations were clustered into two groups, corresponding to their geographic locations. The low within-population genetic diversity and high genetic differentiation among S. dorogostaiskii populations factor into their endangered designation. This genetic analysis reveals that all populations are equally threatened, and community-based conservation is appropriate for these species.

Fritillaria dagana Turcz. has a restricted global distribution, occurring only in southern Siberia andnorthern Mongolia. Concerning its restricted distribution and endangered conservation status, we aimedto forecast its current and future suitable habitats as well as distribution shifts for 2050 and 2080. TheMaxent model with different scenarios (representative concentration pathway 4.5 and representativeconcentration pathway 8.5) was used to analyze 113 georeferenced records of F. dagana using 19bioclimatic factors from the WorldClim database. As a result, the amount and variance of precipitationand temperature, together with elevation, were shown to be the most significant factors affecting thespecies’ distribution. In particular, precipitation during the plant growing season had the greatest impact(55.2% variability) on the species distribution. Climate change was expected to cause a minor shift in thedistribution of suitable habitats toward the north and an increase in habitat continuity, indicating thatthe climate will become more favorable for the growth of species and in the future. The species’ highlysuitable area will remain primarily concentrated in its current potential distribution area in centralSiberia (around Lake Baikal). The species’ conservation status was determined to be near threatened,emphasizing the great relevance of facilitating proper conservation measures for F. dagana.

During a floristic survey of Khar-Us Lake and its associated wetlands in Khovd Province, we found sevenspecies and two hybrid nothospecies that have not previously been recorded in Mongolia. These taxawere found in seven localities and included Hydrilla verticillata (L.f.) Royle, Najas flexilis (Willd.) Rostk. &W.L.E. Schmidt, N. minor All., and N. tenuissima (A.Braun ex Magnus) Magnus (Hydrocaritaceae);Potamogeton angustifolius J. Presl (Potamogetonaceae); Ceratophyllum platyacanthum Cham. subsp. oryzetorum (Kom.) Les (Ceratophyllaceae); Aldrovanda vesiculosa L. (Droseraceae); Veronica anagalloidesGuss. (Plantaginaceae); and Utricularia japonica Makino (Lentibulariaceae). Two of these genera,Hydrilla Rich. and Aldrovanda L., were also newly recorded from Mongolia. The addition of these taxa tothe present Mongolian flora list brings the numbers of registered taxa and genera to 3,200 and 686,respectively. The morphological characteristics, diagnostic features, and distribution of these taxa inMongolia are described in this report.
Micropropagation of the Mongolian medicinal plant Zygophyllum potaninii via somatic embryogenesis
Gun‑Aajav Bayarmaa,이나념,강호덕,Batlai Oyuntsetseg,문흥규 한국식물생명공학회 2018 Plant biotechnology reports Vol.12 No.3
The Mongolian medicinal plant Zygophyllum potaninii has been assessed as an endangered species with regional status. We applied the somatic embryogenesis technique using aseptic in vitro germinants of the plant as an effective propagation technology. The seed germination rate in vitro was 16.5% after 2 weeks of culture. Embryonic calli (EC) and somatic embryos (SEs) were induced using the cotyledon or hypocotyl segments of the germinants. Calli were effectively induced on MS medium supplemented with 0.1 mg/L 2, 4-dichlorophenoxy acetic acid (2, 4-d) and 0.5 mg/L 6-benzylamino purine (BA). The callus was composed of pale yellow or pale green friable cells. SE formed from EC only on Murashige and Skoog medium (MS) with 0.5 mg/L abscisic acid (ABA). Other concentrations of ABA failed to induce SE formation. All SEs germinated in MS medium with different salt levels. However, normal plant conversion was achieved only on half-strength MS medium. The converted plantlets were effectively acclimatized in vitro in sand and transferred to a mixture of sand and perlite (1:1 v/v) in the greenhouse. After 8 weeks of culture, 55.4% of the plants survived. This is a first report of propagating the medicinal desert plant Z. potaninii via somatic embryogenesis and plant regeneration.

A floristic study of Eastern Mongolian Steppes has been conducted during the growing season of 2014 and continued in 2017, when we focused more on the Numrug Strictly Protected Area. Major objectives of this study were to assess floristic diversity of Eastern Mongolian Steppes and to review the conservation status of some endangered, rare, and very rare species. A total of 488 taxa of vascular plants, which belong to 254 genera of 75 families, including three endemic and 16 subendemic species were sampled. Among these were three endangered, three vulnerable, five near threatened, 16 very rare, and 39 rare species. Remarkably, Myriophyllum sibiricum and Typha latifolia are newly recorded for the flora of Mongolia. Moreover, new distribution records of some species were noted in four phytogeographical regions of Eastern Mongolia, such as Foothills of Great Khingan (30), East Mongolia (12), Mongolian Dauria (11), and Middle Khalkha (3). Finally, we assessed regional conservation status of the five species (two endangered and three vulnerable) from the East Mongolia using the International Union for Conservation of Nature Red List criteria and categories.
