Campylopiis atrouirens is also very characlerislic, with its dense 

 cushions covering laige areas of Ihe turf, and allowing no oppor- 

 tunity for the growlh of flowering planls. Other inosses make their 

 appearance in the moist bogs, viz. Ambhjstegia (A. stellatnm and 

 intermedium), also liverworts, e. g. Pellia Neesiana ; some other mos- 

 ses of the boggy-moor association are Dicraniim scoparium, Gym- 

 nocybe pahisiris, Astrophylliim horniim and Acrocladium cuspidatiim. 



Generally speaking the moss-vegelation is extremely luxuriant 

 and consists of many species. Amongsl others we can ahvays 

 find in the real moist bogs, those species of Hylocomia, which 

 appear to me to be the most characteristic for the somewhat drier 

 grass-moors. The growlh-habit of the Sphagnum species differs 

 considerably from that found in less insular climates; the piants 

 never form real Sphagnum-moorti on the Færoes (nor on Iceland, 

 as far as I know). In other words, there are no moor-areas covered 

 with a carpet of Sphagnum in which a few flowering piants are 

 scattered. Even in those piaces where I saw Sphagnum most do- 

 minant, there was a considerable proportion of olher mosses and 

 flowering piants. This peculiarity has already been pointed out by 

 C. Jensen (1897, p. 202). 



Turning now from the mosses to the vegetative features of do- 

 minant flowering plant s, it will be found that the boggy-moor 

 includes species with subterrean wandering shoots (Eriophorum, 

 Carex panicea, C. Goodenoughii, Triglochin pahistre and Narlhecium), 

 other species which are spot-bound (Carex flava, C. steUulata, Leon- 

 todon, Caltha, Pinguicula, Molinia and the biennial Pedicularis) ; 

 and others more or less adapted for wandering by means of epi- 

 terrean shoots (Ranuncnhis flammula and Agrostis canina). The 

 species with subterrean shoots prevail over the others because of 

 their mode of growth, and they will always dominate on a bog 

 area. 



There is not much to say regarding the flowering and fruit- 

 ing of the chief piants mentioned. The »grass-like« species are all 

 wind-pollinated. Some of the »flowering« herbs (Narthecium, Caltha, 

 Ranunculus) have open flowers with yellow petals, and are presum- 

 ably visited by flies or are self pollinating; a few are more highly 

 developed »insect-flowers« , e. g. Pedicularis, Pinguicula and Leon- 

 todon. Fruiting is very likely abundant and regular in every species, 

 even in bad summers. 



The species already mentioned are, in my opinion, the most
