About eighty Australian species of Mamnca are known ; with very few exceptions all of them are 
extratropical. The great majority belong to the two genera Cryptandra and Pomadvmx, or to their imme- 
diate allies. About an equal number are found on the Baal and Weal Coaate, and Bona are common to 
both. The West Coast species are by far the most peculiar, in so far as thai ;.i! 
confined to Australia, except Pomaderris, whereas the Asiatic genera I 
and the South American genus Discaria, are all found on the North and Kast i 
six or eight tropical Australian species, including several \ 
one tropical species of the Polynesian genus AlphUonia. Of the a!; 
are no Tasmaniau species, but about a dozen Eastern and Tropical Australian.
