Examining first tlie general distribution of the Flora we find 
that, of the 95 species, 36 are species cosmopolitan in the tropics, while, on 
the other hand, no fewer than 38 are confined to Asia, Of the remain¬ 
ing 21, whose distribution is confined within the old world but extends 
beyond the limits of Asia, only four occur in Australia, Polynesia and 
Africa as well as in Asia ; two occur in Asia, Australia and Polynesia ; 
four in Asia, Australia and Africa ; and three in Asia, Polynesia and 
Africa. Six are confined to Asia and Australia, two to Asia and Africa, 
one to Asia and Polynesia. The following table shews this more clearly, 
and at the same time indicates the relationships that subsist between 
the distributional features of the species and, on the one hand, their 
habitat, on the other, their habit.

There is no progressive feature in the general distribution of the 
species; while the highest number of any of the classes is that of 
species confined to Asia, the next highest is that of species cosmopolitan 
in the tropics. The cosmopolitan or nearly cosmopolitan species 
are however, to a large extent cultivated plants and weeds of 
waste places or marshes. In the case of the species confined to Asia
