298 MR. J. BALL’S SPICILEGIUM FLOR® MAROCCAN®. 
and only 15 species are confined to the Macaronesian Islands, 
under which name I include Madeira along with the Canary 
Islands. This proportion will doubtless be somewhat increased 
when we know more of the coast vegetation between Agadir and 
Wadnoun ; but the figures tend to show that the separation of 
those islands must date from a period even geologically speaking 
remote. 
With a view to exhibit further the characteristics of the 
Marocco flora it may be convenient to give a summary of the 
results of the foregoing Table, showing the absolute number 
of species or subspecies of each of the principal Natural Orders, 
and the percentage which they bear to the total number of Pha- 
nerogamic species, this being 1627.

It will be seen that the proportion of Composite, Leguminosae, 
and Liliacee is unusually large, whilst that of Graminee and 
Ranunculacez is exceptionally small. Still more characteristic 
of the Marocco flora is the small proportion borne by some natu- 
ral orders that usually take a prominent place among the vege- 
table population in mountain countries in the north temperate 
zone. Thus we have of Rosacee but 16 species, of Saxifrages 5 
species, of Primulacez 7 species, of Gentianex 8 species, and of
