THE FERNS OF SOUTH AFRICA 
Of the endemic species 1 6 occur only in the Cape Province 
(West, East and Kaff.), 16 occur only in the rest of South 
Africa, and 26 are common to both these areas, so the Cape 
Province flora includes 42 species endemic to South Africa, 
and the other Provinces together contain an equal number. 
No genus is confined to South Africa ; the nearest approach 
is Mohria, which however occurs in other parts of Africa and 
its islands. Of the 220 South African species the repre- 
sentation abroad, so far as known, is as follows :

Of the 44 British species of Filices 13 species are also
