Geographical Distribution of Leguminosz. 
In 1855, Alphonse De Candolle’* indicated the tropics as 
the probable home of the Leguminosze and, in support of 
this belief, he pointed out the gradual diminution in num- 
bers of species as the tropics are left behind in both — 
Northern and Southern Hemispheres. De Candolle made 
this announcement at a time when very few legumes had 
been recorded from South Africa and extra-tropical Aus- 
tralia; nevertheless, the known distribution of those plants 
in these two countries has not invalidated his conclusion. 
The Mimosez and Ceesalpinies are more characteristic of 
the tropics than are the Papilionaceze. The Mimosez with 
its vast genera Acacia, Mimosa, Inga, Pithecolobium, and 
Calliandra, possesses no indigenous representative in 
Europe, although Prosopis occurs in Cyprus. The Cesal- 
pinieze, possessing about eighty genera—one genus alone
