Agrostis viilgaris, Poa pratensis, Holcus lanahis, Holciis mollis and 

 Anthoxanthum. The most frequent secondary grass-like piants are 

 Festuca rubra, Agrostis stolonifera, Poa trivialis, Luzula multiflora, 

 Equisetum siluaticum and in the moister Bo's Junciis lamprocarpus, 

 Carex Goodenoughii and Equisetum palustre. 



The »flowering« herbs form a goodly array. Trifolium repens 

 is both common and characteristic. The following may be given

as being frequent: Ranunculus acer, R. repens (in the younger and 

 moister Bo's), Bellis perennis, Rumex acetosa, Leontodon autumnalis, 

 Lychnis flos cuculi, Alectorolophus minor and Euphrasia horealis. 

 Aniong the numerous less important species some merit special 

 mention as they hardly ever occur outside the Bo; tliey are Vicia 

 cracca, Lathijrus pratensis, Myosotis arvensis, M. versicolor, Viola tri- 

 color, Achillea millefolium and Tussilago farfarus. Several of the 

 last-named have doubtless been introduced bj^ man, in faet this is 

 probably true of most of them. 



All the species of the Bo are common piants of the fields and 

 meadows in the northern part of Central Europe, for exainple 

 with us in Denmark ^ None of them are specially northern in 

 character. 



' Euphrasia borealis is, however, an exception ; it.s place being taken in 

 Europe by other species of Euphrasia (e. g. E. brevipila Burnat & Gremli).
