450 PROCEEDINGS OF SECTION D. 
Acacias.—The principal species of this genus in these parts is 
A. aneura, F.v.M., the Mulga, two forms of which were seen, one 
having very narrow leaves. They have been cut down for fodder, 
and also eaten down very extensively throughout the district. 
Plate XXIV. 
The Gidya, Acacia homalophylia, A. Cunn., is the largest Acacia 
to be met with. The unpleasant odour from the foliage of this 
tree, especially after rain, is said to often cause a kind of fever in 
stockmen and others. I did not notice that stock ate the leaves, 
but was told that they sometimes eat the young pods. 
Plate XXIII. 
Acacia salicina, var. varians, was noticed growing near water. 
On the banks of the river, and its billabongs, was growing 
Acacia stenophylla, A. Cunn., the Dalby Myall, with long drooping 
leaves and pods, the latter moniliform. ‘This forms a very graceful 
shrub, 
Other Acacias were A. harpophylla, F.v.M., the Brigalow, with 
long, boomerang-shaped, silvery leaves—Plate XXI; A. Oswaldi, 
F.v.M. ; A. decora, Reichb., with its light-green foliage and thin 
pods, making a most ornamental shrub; and A. tetragonophylla, 
F.v.M., a straggling shrub with globular heads of yellow flowers, 
and clumps of short needle-like leaves. 
MYRTACE. ‘ 
As in most parts of Western Queensland, the commonest 
eucalypt is #. microtheca, F.v.M., the “Coolibar.” Plate X XI. 
The largest eucalypt of the district is Mucalyptus rostrata, Sch., 
which is found by the side of the river and its billabongs. The 
trees were laden with flowers, and those on the long drooping 
branches produced a most attractive sight. At Koopa, most of 
the trees had large nests of the hawk of the district. Another 
large eucalypt was £. ochrophloia, F.v.M., the “ Yapunyah.” 
The base of the stem is black, and the upper part, as well as the 
branches, reddish pink. The leaf is large and thick. 
The only other species of the genus noticed was Z. corymbosa, 
Sm. Bloodwood. 
Melaleuca ericifolia, Sm. <A variety of this species was met 
with. 
FICOIDE. 
Masses of Mesembryanthemum cquilaterale, Haw., the “ pig’s- 
face” of our gardens, were growing on the sandy ridges at 
Dilltoppa. 
UMBELLIFERE. 
On the sandhills at Koopa were noticed the dried stems of 
Trachymene cyanopetala, Benth., with seeds attached. This plant 
is not eaten by rabbits or stock.
