_ shady ground and on this account are not to be found 
elsewhere in the environs, most of them, however, occurring 
Although poor in species the moss flora on the sandy or 
somewhat peaty plains of Skagen is very interesting. Among 
rare mosses, observed by us, are to be named : Cephalozia 
pulchella n. sp., G. rubriflora n. sp., which I have not been 
able to identify with any before described species, Gephalozia 
Jackii, Astrophyllum pseudopunctatum, Bryum purpurascens 
(Var.), B. fallax, B. rubens, which have not before been ob- 
served in Denmark, Riccardia fusco-virens. Cephalozia Fran- 
cisci, Scalia Hookeri, Splachnum vasculosum, Bryum lacustre. 
Only few mosses appear to thrive under the here existing 
conditions being frequent and copious, as for instance : Jun- 
_ germania inflata, Bryum pendulum, B. inclinatum, Pohlia 
- nutans, Tortula ruralis, Ceratodon purpureus, Amblystèégium 
_ Kneïfii, A. Wilsoni, Hypnum albicans, Hylocomium prolife- 
rum and H. parietinum. But most species appearhere to carry 
on a precarious and starving existense, as they occur very 
sparingly or in very reduced, meagre and often scarcely reco- 
__ gnizable forms; this is the case with Chomocarpon commuta- 
_tus, Catharinea undulata, Astrophyllum hornum, Bryum 
lacustre, B. ventricosum, Poblia albicans, Hypnum rutabulum, 
H. plumosum, Climacium dendroides, not to mention all the 
species, seen only in the plantation of Skagen. 
The mosses, that go forthest to the north in Denmark are 
Tortula ruralis, Ceratodon purpureus, and Hypnum albicans, 
which we saw growing between Elymus arenarius, Psamma 
arenaria, Eryngium maritimum and Hippophaë rhamnoiïdes 
on the sandhills near to the point of Skagen. 
I desire to express my grateful acknowledgment to my 
friend and fellow-traveler Dr. H. W. Arnell for his impor- 
tant assistance by elaborating of presentially. 
I give here a complete list of the mosses, observed in the 
Musci hepatici. 
4. Marchantia polymorpha L. — In a heathditch near 
Skagen, sparingly and ster. ; in a meadow-ditch near Bunken, 
ster. 
2. Chomocarpon commutatus (Lindenb.) Lindb. — On 
moist heaths by Skagen, common, but ster.
