THK CONTINENTAL FLORA OF SOUTH SWEDEN 239 



Cassubian variant), Adonis vernalis L. (map 3, Plate 14), and Oxytropis 

 pilosa (L.) DC. 



2. Dacian distribution: tliis type occupies a more isolated position 

 in comparison with the former one, thanks to the fact that the species do 

 not exist in steppe districts, for instance, Syringa vulgaris L., TiHa argentea 

 Desf., Rhus cotinus L. 



3. Pontic — South European distribution, for instance, Stipa capillata 

 L. (map 4, Plate 14). 



4. Pontic — (South and) Central I'.uropean distribution, for instance, 

 Melica ciliata L. (= M. nebrodensis (Pari.) A. & Gr.), Aster linosyris (L.) 

 Bernh.; Poa bulbosa L. and Holosteum umbellatum L., which are widely 

 spread by the agency of man. 



5. Some species, occurring on salt steppes and sea shores, may be said to 

 have a Pontic — Subatlantic distribution, for instance, Bassia hirsuta 

 (L.) Aschers. (map. 2, Plate 13), Atriplex pedunculatum L. 



II. Meridio-boreal species. 



1. Pontic— Sarmatian distribution, for instance, Asperula aperina M. B. 

 (comp. Kupfifer 1905), Campanula sibirica L. and bononiensis L., Evonymus 

 verrucosa Scop., Cieum aleppicum Jacq. (comp. Kupfter), Hieracium echioides 

 W. & K. 



b. The Subarctically variant, for instance, Silene tatarica (L.) Pers. (comp. 

 Kupffer), Centaurea phrygia L. — Ranunculus cassubicus L. (map 5, 

 Plate 15) might belong to this group, though it, being a wood species, is 

 not very abundant in the steppe zone. 



2. Ponticosarmatian — (South and) Central European distribution, 

 for instance, Asperula tinctoria L. (map 6, Plate 15) which follows L i c, 

 Veronica spicata L. (map 7, Plate 16), Trifolium montanum L. and alpestre 

 L., Lavatera thuringiaca L., Carex praecox Schreb. (schematic map in 

 Sterner 192 i a. At the present time the species is also recorded from Fin- 

 land; Medd. Soc. Fauna et P1ora fenn., Bd 47 (1921), p. 47). Melampyrum 

 nemorosum L. (map 8, Plate 16) and Crepis praemorsa (L.) Tausch (map 9, 

 Plate 17) resemble type III: 2 through their comparatively scant distribution 

 in steppe districts; Anemone silvestris L. (map 10, Plate 17) forms a transi- 

 tion to the following variant c through its occurrences in Subarctic Russia. 



b. Some species differ in having a distribution area in Prance stretchnig 

 farther west, such as, for instance, Phleum Boehmeri Wib. (map 11, Plate 

 18), Cjmanchum vincetoxicum (L.) Pers. (map 12, Plate 18), Prunella grandi- 

 flora Jacq., Vicia tenuifolia Roth. 



c. The Stiharctically variant, for instance. Delphinium elatum L. and Ge- 

 ranium palustre L. which in the Subarctic region occur only in northern
