410 RIKARD STERNER 



Thalicl)-um aqiiilegiifolium L, — W. and C. Russia, in S., E., and N. to Volh. (53), 

 Kiev (53), Kursk (2), Voron. (70), Tamb. (42), Ryazan {iz)i Niz-Novg., Vladim. (13), 

 Kostr., NE. Novg. (4) [Olonets-Karel. (17)]. — In W. and NW. to SE. France (in 

 Auvergne and the Jura), the lowland on the upper Rhine, Thuring., Brandenb. (I), 

 Pomer. (E. of the Oder), S-most Swed.: Skane and S-most Smal., SE-most Finl.: 

 Ladoga-Karel. and Olonets-Karel. — D. T. Ill: 2. 



Ulmiis foUacea Gilib. — S. Russia, in N. to Grodno (53), Minsk (53), Volh. (53, 

 Koeppen), Chernig. [f. suberosa (Ehrh.) (44)], Kursk (i), Tamb. (42), Sarat. (24), [S. 

 Samara and S. Orenb. (cf. Korshinsky 1898)]. — The species reaches its W. limit in 

 France where, however, its distrib. as a native can hardly be determined the species 

 being abundantly cultivated over the whole of the country. As a real native it is 

 lacking in Belg., Holl, NW. Germ, (at least in the Rhine-Prov., Westph., Hanover 

 and Hoist.), and in Denm. In SE-most Swed. on Oland and Gotl., II. — D. T. [I: 4.] 

 Also V. T. 3. 



Uimus laevis Pallas. — Almost the whole of Russia, in N. to [Onega-Karel.] SW. 

 Archang. : to 63° on the rivers in "Auenwalder" (40), W, Vologda: in E. to Ustjug 

 (21, 58, 59), the whole of Vyatka, N. Perm. — The species being abundantly cultivated 

 its W. and NW. limit in Europe can hardly be determined. Accord, to Schneider 

 1906, p. 213 it is found as a real native in S. and E. France. It it said to occur 

 as a native in SE. Belg., Westph. (a few scattered occurr.) [in Hanover: Bremer-Walde 

 and in Hoist, and Schleswig very sparsely; ? native]. A real native on Oland, I, in 

 the C. part of the island. SE. Finl. rare, in N. to S. Satakunta, S. Karel., and 

 Onega-Karel. — D. T. II: 2 c (— III: 2 c). 



Viola mirabilis L. — Almost the whole of Russia. — As to its W. and N. limits 

 in Europe see Plate 22. — D. T. II: 2 c — III: 3 b. 



8. SPECIES OF MARSH ASSOCIATIONS. 



Achroanthes monophyllos (L.) Beene. — See Plate 21. — D. T. Ill: 2. 



Alopecurus veniricostLS Pers. — The species being confused with certain forms of A. 

 pratensis its Russian distribution seems not yet to be accurately determined. Accord, 

 to 53 it does not occur in Poljesje and the neighbour, governments of W. and C. 

 Russia. Accord, to Korshinsky 1898 it occurs in E. Russia in the steppe districts 

 (Samara, Orenburg, and Perm) and "in decliviis lapidosis montium jugi Uralensi bo- 

 realis". Accord, to statements in recent publications it is widely distrib. in S. Russia 

 on the shores of the Black Sea and the Caspian Sea as well as in the steppes: 

 Ekaterinosl. (72), Taurida (54), Khark. (8, 47), Kursk (76), Tamb. (42), Sarat. (24). 

 In the herb, of the Upsala Botanical Museum I have seen the species from Sarepta. 

 [From Turkest. it is reported by Regel (Descript. plant, etc., Petrogr. Acta, Bd. 7, 

 Ease. I, 1880, p. 654)]. In N. Russia it is certainly distrib. on the shores of the 

 Arctic Ocean (cf. Conspectus Fenn., Pars iii, p. 356 and 62) and is said also to be 

 found for some distance inland (in the neigbourh. of the town Vologda accord, to 

 59?). — Outside Russia it occurs in the Scandin. North (see p. 372). It is also said 

 to exist in Switzerl. and in SE. France (Puy-de-D6me) — reports which require verifi- 

 cation. A critical taxonomic study is certainly necessary. — D. T. [II: i b]. Also 

 V. T. i:a. 



Arabis Gerardi Bess. — M. Russia; in N. to SW. Archang.: Shenkursk (40), 

 Petrogr. (43), S. Novg.: Borovitsh (26), W. Pskov (18), Smol. (11), Tver, Vladim. (13),
