Germany; for UBU and the Herbarium of Khovd University: B. Oyuntsetseg from the Botany Department of the National University of Mongolia, Ulaanbaatar, and D. Darichand of the University of Khovd, Khovd, Mongolia.
A first scientific evaluation of the collected material revealed, that some species were new records for the whole Mongolia, and others were new findings for certain regions of Mongolia. References are Grubov (1982) and Gubanov (1996) if not stated otherwise. The present article covers the families: Amaryllidaceae, Aspleniaceae, Asteraceae pro parte, Boraginaceae, Caryophyllaceae, Crassulaceae, Lamiaceae, Papaveraceae, Rosaceae, Saxifragaceae and Scrophulariaceae. In a second part, other families will be treated.
New species for the flora of Mongolia
Caryophyllaceae
Silene sibirica Pers.
Khovd Aimag, Baytag-Bogd, northern foothills, the river valley Naryyn Chargaytin Gol, floodplain, 45°19'868" N, 90°54'209" E, 1818 m, 08. 07. 2013 (ALTB).
Papaveraceae Glaucium elegans Fisch. et CA. Mey. Khovd Aimag, Bulgan Sum, Dzungarian Gobi, 100 km SSW ofBulgan, 45°18'04,1" N, 90°56'56,9" E, 1880 m, 08. 07. 2013 (OSBU 22896); Khovd Aimag, Baytag-Bogd, northern foothills between the rivers Baruuk Chargaytyn Gol and Naryyn Chargaytyn Gol, 3 km north-west of parking space Tegshee Davaadorj, steppe, 45°18'067" N, 90°56'943" E, 1880 m, 08. 07. 2013 (ALTB).
Rosaceae Potentilla pamiroalaica Juz. Dzungarian Gobi: Khovd Aimag, Baytag-Bogd, Mt. Altan Obo, north-eastern slope (near the border), 45°12'20" N, 90°52'30" E, 2800-3200 m, 06. 07.2013 (ALTB).
The distribution area is similar to P. pamirica Th. Wolf. Previously, P pamiroalaica has been reported for Russian Altai Mountains (Kurbatskyi, Ebel, 2011).
Potentilla regeliana Th. Wolf Khovd: Bayan-Ulgii Aimag, Karalahti Ridge, the pass Obortyn Daba, 49°19'143" N, 89°47'370"
Fig. 1. Collecting sites of the Mongolian-German-Russian botanical expedition in summer 2013.
E, 2632 m, 18. 07. 2013 (ALTB).
This plant was mentioned by Grubov (1982) with the only locality "Mongolian Altai, left tributary of the river Uljasutay-Gol". The corresponding specimen is in LE, but in fact it corresponds to Poten-tilla evestita Th. Wolf. Description and illustration of P regeliana Th. Wolf is given in Wolf (1908). Wolf assigned it to the group Rivales (= sect. Rivales (Th. Wolf) Juz.). Currently, many authors merged P regeliana with P evestita. However, R. Kamelin (1998) considers this two species as independent and pointed out a relationship of P evestita with the P. nivea group (and not with the Rivales group).
Potentilla regeliana is described from West China (Borohoro ridge), and is distributed mainly in Dzungaria. It is characterized by the following features: terminal leaflets of all basal and most of the lower stem leaves with prominent petioles up to 1 cm long (in P evestita, petiolate terminal leaflets can be reraly found in some basal leaves); leaflets with 4-6 unequal teeth on each side (vs. 5-9 more or less identical teeth in P evestita); plant pubescent with simple soft hairs and numerous sessile glands (P evestita on the underside of the leaves is often wooly with silky hairs, glands are developed primarily in the upper part of the plant).
Potentilla turczaninowiana Stschegl.
Dzungarian Gobi: Khovd Aimag, Baytag-Bogd, Mt. Altan Obo, north-eastern slope (near the border), 45°12'20" N, 90°52'30" E, 2800-3200 m, 06. 07. 2013 (ALTB).
Together with P. turczaninowiana, some plants similar to P saposhnikovii Kurbatsky grew. The latter is treated by Sojak (2004, 2012) as a synonym of P. turczaninowiana. Indeed, P saposhnikovii may be a juvenile (2-3-year-old) form of P. turczaninowiana. These taxa require special studies in order to clarify their relationship and status.
New floristic finding for certain
phytogeographical regions of Mongolia
Amarillydaceae
Allium amphibolum Ledeb.
Depression of Great Lakes: Khovd Aimag: Manhan Sum, western flank of Jargalant Mt. Chain, 65 km SE of Khovd, 40 km NNE of Manhan, 47°44'31,5" N, 92°25'55,8'' E, 1970-2700 m, 12. 07. 2013 (OSBU 23009).
The new collecting points broaden the hitherto known distribution area (Gubanov 1996, Friesen 1995) to the east.
Allium bidentatum Fisch. ex Prokh.
Mongolian-Altai: Khovd Aimag: Tsetseg Sum, Mongolian Altai, 140 km E of Bulgan, Byangol Byag at the river Bayan Gol, 46°13'58,5" N, 93°22'22,3" E, 2381 m, 03. 07. 2013 (OSBU 22619).
Allium bogdoicolum Regel
Depression of Great Lakes: Khovd Aimag: Manhan Sum, western flank of Jargalant Mt. Chain, 65 km SE of Khovd, 40 km NNE of Manhan, 47°44'31,5" N, 92°25'55,8'' E, 1970-2700 m, 12. 07. 2013 (OSBU 23008).
Allim pumilum Vved.
Dzungarian Gobi: Khovd Aimag, Bulgan Sum, Dzungarian Gobi, 105 km SW of Bulgan, Baytag-Bogd, border area to China, at arm of the river Budiin Chargaytin Gol, 45°15'00,4" N, 90°56'08,1" E, 2143 m, 07. 07. 2013 (OSBU 22829).
Allium pallassii Murray
Dzungarian Gobi: Khovd Aimag, 8 km north of Uench. Nanophyte steppe, 46°08' N, 92°02' E, 19. 06. 1999. Smirnov S.V. (ALTB)
This is the first proof for this species for the Dzungarian Gobi. Sanchir (1992) mentioned this species for the first time for the Mongolian flora but without giving locations, nor any details of its distribution. Friesen (1995) suggested possible distribution of this species in the Dzungarian Gobi.
Allium ubsicolum Regel
Khovd: Bayan Ulgii Aimag: Tsagaanuur Sum, Mongolian Altai, 75 km NNW of Ulgii, close to Mongolian/Russian border near Tashanta, 49°33'32,2" N, 89°27'41,9'' E, 2276 m, 18. 07. 2013 (OSBU 23131).
This new point for Allium ubsicolum is not too surprising, as it was found previously on the Russian side of the ridge Sailyugem (Friesen, 1988).
Aspleniaceae
Asplenium altajense (Kom.) Grub.
Depression of Great Lakes: Khovd Aimag, ridge Dzun Jargalant, the river valley Ar Shaatan Gol, 47°44'442" N, 92°26'965" E, 2000-2500 m, 12. 07. 2013 (ALTB).
The species was reported for the Depression of Great Lakes by Revushkin et al. (2001) from the single locality (SW vicinities of Khovd) on the border between this region and Mongolian Altai. The present finding undoubtedly belongs to the Depression of Great Lakes.
Asplenium nessii Christ
