ACACIA NIGRICANS. 
Ciass. Order. 
POLYGAMIA MON(ECIA. 
A native of New Holland. It was intro- 
duced in the year 1810. With us it flowers 
freely during the spring months. It is one 
of those plants which are seen to the greatest 
advantage in the full ground in a conserva- 
tory, as it then flowers much stronger than 
in a pot; but it has not perfected its seeds 
with us. Its soil should be loam and peat, 
furnished with more leaflets. 
another plant, * which has these 
still longer and more numerous than his : 
all other respects they seem to accord, and 
cannot be considered as distinet species.
