F. C. KIÆR. CHRISTIANIAS MOSSER. 



subalpine mosses, not observed in the lower parts, for instance 

 Dicranum Starkii, Desmatodon latifolius, Grimmia funalis, Gymno- 

 mitrium concinnatum and Scapania uliginosa. Here is also found 

 the Hypnum montanum, known only from North-America. 



Kols a as (12), the best examined locality of any extent, con- 

 tains 6.14 km^. Here have been gathered not less than 183 mos- 

 ses and 46 hepaticae or above one half of the mosses of Christiania, 

 and about a third part of the mosses known in Norway. It ought 

 also to be observed, that the pleurocarpi here are uncommonly richly 

 represented (41.5 7o of the mosses) and amount almost to half the 

 number of all pleurocarpi of Norway. 



Amongst the rarer species which here are gathered we may 

 name Sarcoscyphiis {Marsupelld) ustulatus, Tayloria tenuis, Cono- 

 stomum boreale, Nechera Besseri, Anomodon apiculatus and Brachy- 

 thecium Geheehii. The 3 last cited mosses have also been collected 

 on the Skogumsaas; on this hill the author has had the plea- 

 sure of examining mosses in 1880 in company with Mr. A. Geheeb 

 and 1882 with Prof. S. 0. Lindberg. 



Several of the above quoted mosses belong to the rarer ones 

 in Europe; besides, the following, collected at Christiania are per- 

 haps worth citing here: Dicranella Grevilleana, Dieranum elatum 

 (very commonly), Barbula brevirostris (abundant in several places), 

 IJlota ciirvifo/ia, Orthotrichum Blyttii, (detected by Prof. M. N. Bl ytt, 

 but later not observed), Encalypta brevicollis, Splachnum vascu- 

 losum, S. luteiim, DiseeUiim niidum, Webera Schimperi (not observed 

 in later years), Fontinalis dalecarlica, Dichelyma falcatum, Nechera 

 oligocarpa, Thuidiiim Blandoivii, Plagiothecium piliferum and Jiin- 

 germannia cordifolia. 



North America has not less than 313 species of mosses in 

 common with Christiania. 



About one sixth of the mosses collected at Christiania belongs 

 to the cosmopolitan mosses (Musci omnivagi), of which a list is in- 

 serted pages 19—20.^ These 66 species are all found at Christiania, 



1 The mosses, whicli are gathered in all continents of the world biit one, are cited 

 pages 20—21.
