THE BOEONIA. 
there are twenty-one species of Boronia cul- 
tivated in the gardens of England ; and among 
these there exists considerable variety. For 
real beauty and utility, however, we should 
prefer B. serrulata, triphylla, and pinnata to 
all the rest, to which, perhaps, for the sake of 
greater variety, B. viminea might be added. 
We shall, however, enumerate the different 
kinds, in order that they may be known. 
They form three groups^ — those with simple, 
with trifoliate or trifid, and with impari- 
pinnate* leaves. 
THE SPECIES OF BORONIA. 
There are now many species of this genus 
cultivated in English gardens. In some the 
leaves are simple, in others they are pinnate.

describe the principal of them.
