Plants of the leguminosae and compositae, were by far the most prevalent; the colour of the former, generally a showy red, that of the latter, a bright yellow.

Belts of open forest land, principally composed of the Box-tree of the Colonists (a species of Eucalyptus), separate the different plains; and patches of scrub, consisting of several species of Acacias, and of a variety of small trees, appear to be the outposts of the extensive scrubs of the interior.

There are particularly three species of Acacias, which bestow a peculiar character on these scrubs: the one is the Myal (A.pendula)--first seen by Oxley on Liverpool Plains, and afterwards at the Barwan, and which exists in all the western plains between the Barwan and Darling Downs--whose drooping foliage and rich yellow blossoms render it extremely elegant and ornamental.

The second, the Acacia of Coxen, resembles the Myal (without its drooping character), its narrow lanceolate phyllodia rather stiff, its yellowish branches erect.

The third, is the Bricklow Acacia, which seems to be identical with the Rose-wood Acacia of Moreton Bay; the latter, however, is a fine tree, 50 to 60 feet high, whereas the former is either a small tree or a shrub.
