The word. Acacia, is supposed to have had its 
origin in the Greek akaso, to sharpen ; in allusion 
to the sharp stipules of many Acacias. 
The genus Acacia is quite a monster in extent, 
a heterogeneous mass. Decandolle, twenty years 
ago, described nearly five hundred mimoseous 
plants. Fifteen hundred, it is probable, are now 
known, of which Acacia contains by far the greater 
number; indeed, the genera Inga and Acaciaseemto 
be the receptacles for all those species to which no 
other resting place can be allotted. We are, how- 
ever, glad to notice that Mr. Bentham has under- 
taken a re-arrangement of this section. 
A primary subdivision of this genus has been 
proposed by Mr. Bentham, dependant on a char- 
acter which may be examined in our present plant ; 
one that is so remarkable, and easily distinguished, 
that it is a convenient division, although not an 
excellent botanical section, from its presenting no 
peculiar modification of flowers or fruit. 
The character to which we allude is the presence 
of what are called phyllodia, instead of true leaves. 
This peculiarity may have escaped the observation
