1. Mediterranean Region. 
The Mediterranean or, as it might perhaps be more accurately 
designated, the Mediterraneo-Persian region, must, so far as 
Compositæ are concerned, be taken in a rather wider sense than 
that assigned to it by Grisebach ; for the whole of Boissier's * Flora 
Orientalis’ is so strongly impressed with the Mediterranean type 
as to be inseparable from it in a generalview. The region would 
thus comprise the three great South-European peninsulas up to 
the southern declivities of the Pyrenees the Cevennes the Alps 
and the Balkan, Asia Minor and the Levant generally, including 
Persia and Afghanistan, although with eastern limits at present 
somewhat vague ; whilst the southern boundary would lie along the 
tropical or subtropical little-known mostly desert lands of Arabia 
and Africa to the Atlas, extending westward in some respects even 
to the Canary Islands, although on the present occasion their 
Composite are not included in the preceding Table as requiring 
separate consideration from their insular character. It might be 
thought, perhaps, that this vast region ought to have been divided ; 
and there certainly are differences between many of the Composite 
races of the east and the west. There is, for instance, no Cousinia 
west of Boissier's flora, no Tolpis or Calendula in Persia; but in 
general the genera of the two extremities are so blended together, 
so many of the smaller ones with species of limited areas are
