Dahlstedt, H., The Hieracia from the Faeroes. (Botany 



of the Faeröes. II. Copenhagen [Nordiske Foiiagj 1903. 



p. 625—659. With 2 plates.) 



The author has determined a rather large collection of Hieracia 

 from the Faeröes, gathered by J. Harty, C. H. Ostenteid, H. G. 

 Simmons and E. Warming during the summers of 1895, 1896 and 

 1897. All the forms examined are new to science, but mostly related 

 to forms which occur in the neighbouring countries. They belong to the 

 follovving groups of the genus: 



Viilgata, sub-group Subcaesia 2 species, 



„ „ V tilg ata geimina 4 „ 



Rigida 3 „ 



Cerinthoidea 12 „ 



(of which two are varities), 

 Alpestria 2 „ 



21 species, 

 and 2 varietles. 



The author states that the greater part of the FaerÖese forms 

 are Atlantic forms, especially all the Cerinthoidea. He means that 

 this fact lends considerable weight to the theory of a post-glacial land- 

 connection from Great Britain to I c e 1 a n d. „It may be argued that 

 these forms having flying apparatus, may easily be carried to great dis- 

 tances by the help of the wind; but on the one band, have proved that 

 the fruits of the Hieracia usually do not spread very far, and on the 

 other, that the Cerinthoidea have heavier and larger fruits than the 

 greater part of the other groups, with exception of Oreadea and Alpina 

 vera, consequently, if it be maintained that they are converged across 

 larger areas by the agency of the wind, then they ought to be more 

 poorly represented in the Faeröes than the rest of the groups which 

 have lighter fruits."

 phylloides Dahlst. n. sp., H. ardisodon Dabist, n. sp. ; Vulgata genu-
