the flatter regions of Central Sweden and a Smalmid-distribiitiofi which is 

 limited or concentrated to the broken regions in the nortJi-east. (See Figs on pp. 

 315 and 319.) 



Some other species previously mentioned Dracocephalum Rtiyschiana (Plate 4), 

 and Pulmonaria angustifolia (Plate 4), as well as Ajtiga genevensis are also connected 

 with certain steppe species as regards both mode of occurrence and distribution 

 in South Sweden. For all these species we have statements as to their occur- 

 rence in meadow-steppe regions (e. g. in the Streletz- and the Kasatz-steppes in 

 the government of Kursk, according to Alechin, 1909 and 19 10), but in that case 

 they most frequently belong to scrubs or forest oases in the steppe region. [Cf. 

 Korshinsky's (1898) information as to the way in which the species appear in 

 the east of Russia]. In the south of Sweden the species appear both in dry 

 meadows and in dry hilly thickets (see Sernander 1908, pp. 54 ff., 61 ff., and the 

 analyses of vegetation on p. 304). The distribution of the species in southern 

 Scandinavia, which is in many cases interesting, has already been mentioned 

 (see pp. 306 ff. and the distribution maps on Plates 3 and 4, and Appendix I.) 

 Some species more or less typical of thin dry forest associations. — In the first 

 place I will briefly treat two species distributed in almost the whole of Middle 

 Europe. A species which is characteristic of dry wooded hillsides throughout 



Middle Europe is Agrimonia eupatoria. Its 

 distribution in Fennoscandia is shown in 

 the annexed map (Fig. 22). This distri- 

 bution would seem to correspond very 

 closely to the maximum distribution of 

 species with a similar mode of occurrence. 

 Thanks to its effective equipment for 

 spreading itself, of course, Agrimonia has 

 a great capacity for reaching suitable 

 localities. 



This species is found nearly all over 

 the south of Sweden, but considerably 

 more abundantly in the eastern than in 

 the western parts. In Smaland its grea- 

 test distribution is on the coast and in 

 the north-eastern interior of the province. 

 The species is very richly represented 

 in the plains of Central Sweden. In addi-
