Mosses occur frequently, but not always, in the undergrowlh, 

 especially if the Bo is a moist one. The dominant species are 

 Hylocomia, but in addition, a number of other mosses have their 

 habitat here, and rarely if ever appear outside the home-field. As 

 examples of these we may mention : Lophocolea bidentata, Hypnum 

 praelongum, H. rutabulum, Pohjtrichiim naniim, and, somewhat less 

 restricted, Catharinea undiilata, AstrophyUiim undulatum and Bryum 

 pallens. 



Lichens are of no importance. Fungi belonging to the Ag-ari- 

 caceae are fairly numerous, but unfortunately I cannot give much 

 information about them. Most of the Agaricaceae given in E. Ro- 

 strup's Hst of Færoese Fungi (1901) were probably collected from 

 the Bo, thus I recollect Panaeoliis campaniilatiis and Tricholoma 

 sulphureum. 



As regards vegetative propagation amongst the phanero- 

 gams, we find that the dominant grasses inchide: I*' distinctly cæs- 

 pitose species (Holciis lanatiis and AnthoxanthumJ ; 2° cæspitose 

 species with runners (^A/7ros/is viilgaris); and 3" distinctly wandering 

 species (Poa pratensis and Holcus mollis). 



Similarly the »floweiing« herbs show much variety in vegeta- 

 tive structure, and as examples ranging from spot-bound to wan- 

 dering species we may mention, Raminciiliis årer, Bellis perennis, 

 Trifoliiim repens and Ramincuhis repens. 



Flowering and fruiting occur abundantly in the grasses and 

 the grass-like piants; but the fruiting does not seem to be so good 

 in the case of several of the »flowering« herbs, such as Lathyrus 

 pratensis, Vicia cracca and Trifolium repens^. 



The lack of insects suitable for pollination, may account for 

 this (see further pp. 915—917). The more simple types of entomo- 

 philous flowers form seed very well; so also do the two annual 

 parasites, which are presumably self-pollinating like many of the 

 other species. 



The appearance of the Bo varies in the same way as any 

 formation, according to the soil-moisture, the age, etc. 



Some examples of tlie »Bo« taken from the different Islands will 

 illuslrate this variation; notes are also included on those examples at 

 Kirkebo, where foreign seed was sown. 



^ 1 cannot say how Tussilayo flowers and fruits, as I have only observed it 

 in the summer.
