Grove III. Northern Furope.—This consists of 15. species, of 
which a considerable proportion belong to the genus Hieracium. Two 
are recorded from the Northern Isles; 5 from within the Aretie 
Circle.

Southern Isles. In this group will be found a great number of our 
colonists or introduced cornfield weeds. According to the range 
Eastward into Asia, the group can be divided into three sections, a 
Section. 1. One hundred and forty-seven species which have been 
recorded from Western Asia or Siberia, but which do not occur m 
India, nor farther East. : : 
Section 2. Fifty-six plants which stretch as far as India, but have 
not been met with in Eastern Asia. : 
Section 3. Contains 21 species which extend to Eastern Asia. ' 
Grovr VI. Temperate Europe and Asia.—This is the largest 4 
our proposed groups, an ins 379 species. About a fourth ij 
27 per cent.) extend North beyond the Arctic Circle, i 
in that respect might be classed as Northern plants; but they Alge i 
Asia and Siberia. : 
ection 2. Kighty-nine species which are found in the Himalay% 
but do not reach Eastern Asia. om 
5 fine 3. One hundred and twenty-five species recorded fro 
astern Asia. 
Group VII. Northern Europe and Asia.—This embraces only 14 
species, nearly all penetrating within the Arctic Circle, and 7 of pant 
recorded from Iceland. 
Roup VIII. Arctic Europe and Asia.—Even smaller than i

Spring Gentian (Gentiana verna), is an Alpine plant, ranging slt~
