This is known as the Black or Green Wattle of the colonists, 
although these names are not applied with any great precision. 
This is not a common species in the colony although rather abun¬ 
dant in the vicinity of both Hobart Town and Launceston ; the 
Acacias in the Government Demesne at Hobart Town being 
almost exclusively of this species. It forms a pretty small tree, 
from fifteen to twenty feet high, flowering from 1st to 25th 
December, being the latest flowering species in the island. The 
seeds do not ripen for twelve or thirteen months after flowering, 
in this respect also widely differing from all our other species. 
It is usually found in stiff clay soil.

Silver Wattle of the colonists. This beautiful species is scat¬ 
tered over all the settled districts of the Island, but is rare in that 
extensive portion of the western side where primary rocks prevail. 
On the side of Mount Wellington, near Hobart Town, and on 
the rich alluvial flats which border the Meander, St. Patrick, and 
other rivers, as well as in some other localities, this species attains 
to a great size; having clean cylindrical trunks seventy to eighty 
or ninety feet high without a branch, and varying from four to 
six or eight feet in circumference near the base. In these situa¬ 
tions it occasionally forms small forests to the exclusion of other 
trees ; and I have supposed them to have grown where fires had 
destroyed the previous occupants of the ground, as the boundaries 
of these forests are usually well defined. This is not, however,
