incomplete exploration of them. 193 species and 14 varieties have 

 been found in the E. Of these 207 forms : — 



126 (ab. 60,5%) are c. 62 (ab. 30%) are suba. 



49 (ab. 24%) are w. c. 8 (3,63%) are alp. arct. 



23 (ab. 11%) are Atl. 

 Of the species 50 (ab. 25%) are Hepaticae, besides 5 varieties. 

 Of these 55 forms: — 



27 (ab. 49%) are c. 18 (ab. 33%) are suba. 



19 (ab. 34,5%) are w. c. 3 (5,45%) are alp. arct. 



7 (ab. 13%) are Atl. 

 10 (5,18%) Sphagna with 1 variety, whereof 5 are c, 6 w. c. 

 and also 1 suba. 



Musci frondosi, 133 (ab. 69%) species, whereof 84 Acrocarpi and 

 49 Pleurocarpi, besides 8 varieties. Of all these 141 forms: — 

 94 (ab. 66,5%) are c. 43 (ab. 30,5%) are suba. 



25 (ab. 18%) are w. c. 5 (3,56%) are alp. arct. 



16 (ab. 11%) are Atl. 

 Barbula reflexa and Plagiothediim denticulatiim (var. Donii) have 

 not been found in the other parts. The northern limit for Barbula 

 reflexa as well as for Metzgeria hamata occurs in this part (Bordo). 



This comparison shows that Sydero in relation to its small 

 area — it forms the smallest part - possesses a large number of 

 species, the next largest in faet. This marked superiority no doubt 

 is due to the southern situation of that island. The similarity of 

 the moss-flora to that of the central part, however, is so great that 

 these 2 parts may very well be united to a S. C. part, in contrast 

 to the somewhat greater northern part: the W. N. E. parts. The 

 following mosses, which more or less belong to southern regions, 

 have only been found in the S. C. part, below 200 m. : — Lepidozia 

 setacea, Odontoschisma Sphagni, Martinellia geniciilata, Mylia anomala, 

 Jungermania inflata, J. socia, J. barbata, J. ovata, Blasia piisilla, 

 Astrophylhim stellare, A. silvaticiim, Philonotis capillaris, Bryum ery- 

 throcarpum, B. fallax, B. cæspiticium , B. Marratii, Pottia crinita, 

 Barbula fallax, Mollia tortilis, Dicramim long if otium , Archidium 

 alternifolium , Oncophorus polycarpus, Glyphomitrium polyphyllum, 

 G. Daviesii, Grimmia affmis, G. trichophylla, Hypmim hians var. distans, 

 H. albicans, Isothecium viviparum, Isopterygium elegans, Entodon 

 orthocarpus, Hedwigia albicans.
