Eeviewing the general distribution of the flora as given in Table 
VI, we find that of the 358 species, 70 are cosmopolitan in the tropics, 10 
more are nearly so, 49 are more or less widely spread throughout the. 
tropics of the old world, 41 extend from South-eastern Asia to Austra¬ 
lasia, while 188 species ai’e confined to South-eastern Asia. The sub¬ 
joined synoptic table indicates these distributional features more exactly 
and gives at the same time the relationship of this distribution both to 
the habit and to the habitat of the species.
