REVIEW. 
struck with the fact that there are so many species common to both 
Europe and America, clearly showing that the two floras, now so 
widely separated, have a common origin, and that they are part of 
that great and ancient Scandinavian flora whose descendants now 
people the world. Still, though there are strong lines of affinity in the 
two floras, a careful analysis of the Manual reveals the fact that there 
are many and marked differences in the two floras. In the Manual we 
have descriptions of about 900 species and varieties, and of these 385 
species are non-European. The following analysis will show the 
whole matter at a glance ; in this I have given the genera in the order 
in which they appear in the Manual; and the first column of figures 
represents the total number of species of each genus as recorded in 
the Manual, the second column gives the total number of non- 
European species of each genus :—
