BY 



C. JENSEN. 



THE Færoes (about 1325 D Kilom.) contain 341 species (incl. 3 

 subspec.) and 50 varieties. Of the 391 forms: — 



226 (ab. 580/o) are c. 117 (ab. 307o) are suba. 



87 (ab. 22» are w. c. 23 (ab. 67o) are alp. arct. 



52 (ab. 130/0) are Atl. 

 Of the species, 95 (ab. 28Vo) are Hepaticae, whereof 4 Marchan- 

 tiaceae, 12 Jungermaniaceae foliosae pleurogamae, 16 Jungermania- 

 ceae folios. opistogamae, 53 Jungermaniaceae folios. acrogamae and 

 10 Jungermaniaceae frondosae, besides 19 varieties. Of these 114 

 forms: — 



48 (ab. 42,5 0/0) are c. 33 (ab. 28%) are suba. 



37 (ab. 32 0/0) are w. c. 10 (ab. 9%) are alp. arct. 



19 (ab.l7 7o) are Atl. 

 17 (57o) species and 3 varieties of Sphagnum, of which 20 

 forms 12 are c, 8 w. c. and 2 suba. 



229 (ab. 67Vo) Musci frondosi, whereof 156 Acrocarpi and 73 

 (ab. 32 7o) Pleurocarpi, besides 29 varieties. Of these forms : — 



166 (ab. 647o) are c. 82 (ab. 32%) are suba. 



42 (ab. 16%) are w. c. 13 (ab. 5%) are alp. arct. 



33 (ab. 13%) are Atl. 



Probably new to science and hitherto only known from the 

 Færoes are: — 



Porella riviilaris var. færoensis, Jungermania alpestris var. am- 

 phigastriata, Astrophyllum undiilatiim var. cuspidatum, Bryiim ven- 

 tricosum var. atlanticum, Pohlia faeroensis, Cawpijlopus Schimperi 

 var. flagellifera, Anisothecium crispiim var. atlanticum, Ambhjstegium
