rrom this analysis, we find ttatthe "Universal" plants of Ireland 

 which, are not equally widespread in Great Britain are generally in 

 the latter island of rather southern range (British-English and English- 

 British) ; and a few are distinctly southern (English) ; this result we 

 might expect from a comparison of the range of latitude of the two 

 islands. The most noteworthy feature of the few other species in the 

 lists is the abundance in Ireland of the distinctly northern (Scottish- 

 Highland) Crepis paludosa. 



Cnicus pratensis has an anomalous range. Though recorded from 

 every Irish division, it is rare in the east and increases westward, 

 becoming abundant in the west and north ; while in Great Britain it is 

 of characteristic English type, being unknown north of Yorkshire. 

 Its range in Ireland is the reverse of that of most English type 

 plants — see fig. i. above. 



In the case of a few other " Universal" plants, their distribution 

 over the country is not even, but it is yet not sufficiently accentuated
