though numerous forms of this gro up occur in the rocky districts 

 ot* Scotland and Scandinavia and in [celand. But as regards the 

 latter group, the climatological conditions prevailing in the Færoes 

 are hardly favourable for ils growlh. What is applicahle to Vul- 

 <l<il<t, etc. mav also be applied lo Foliosa, which are nol repre- 

 sented in the Færoes, though they occur in the three areas just 

 mentioned. Piloselloidea are also totally ahsent, but the latter are 

 also extremely rare in Great Britain, and in Europe the greater 

 part of them have a chiefly eastern and a southern distribution 1 . 

 Lastly, I mav remark, that none of the Færoese forms are identical 

 with those from the adjacent countries, but judging from our pre- 

 sent knowiedge of them, they all appear to be endemic. The im- 

 migrated forms have doubtless originated the latter. But as far 

 as comparison has been possible, they come extremely near to 

 forms from the neighbouring countries. With regard to the Fær- 

 oese Hierdcium-fiora , the faet of its being endemic is not of any 

 great importance, as not only some wider groups of the Hieracia, 

 but also many of its sub-sections (e. g. in Scandinavia) are as a 

 rule endemic.
