fornia to Ohbili, the latter region containing many species 
of these genera. 
It will be advisable at this stage to state the geographical 
distribution of afew important genera, and as a supplement 
to that to prepare a table showing the species of Legumi- 
nosz in one region, such as tropical Africa, which are 
common to other continents or regions. The genera chosen 
in illustration of the first point are Inga, Pithecolobium, 
Albizzia, Acacia, Mimosa, Calliandra, Piptadenia, Parkia, 
Cassia, Bauhinia, Hriosema, Dalbergia, Astragalus, Teph- 
rosia, Indigofera, Crotalaria, and Lupinus. 
The analysis has been taken from Pflanzenfamilien, 
from the Index Kewensis, and from Bentham’s Flora 
Australiensis, his Revision of the Genus Cassia, as well as 
from his Mimosee.
