A slender thornless tree, from 20 to 30 feet in height. “3 
Native of Van Diemen’s Island; where it is known among 
the colonists by the appellation of “ Green Wattle.” Not- 
withstanding its having a smaller finer closer and more 
glaucous foliage than («), the tree known in New South 
Wales by the same denomination; still Mr. Brown is not, 
at present, aware of any mark that in his apprehension 
would justify a theoretical separation of the two into dis- 
tinct species. The leaves retain their soft cinereous ver- 
dure when dry, as perfectly as when fresh, a circumstance 
to which the tree most probably owes the epithet prefixed to 
the english appellation, which is known to be derived from 
the economical purpose to which the branches are applied.
