(2) The ramosa type, comprising A. calycina, A. 
ramosa , A. < yracilipcs , and the doubtful form men- 
tioned above. These species are more or less 
erect, much branched, the leaves smaller than in 
the preceding type, the panicle contracted and 
usually spiciform. Glumes. lemmas, and awns 
are intermediate. The group is confined to the 
schists. 
(3) A. intricate!. This is a very distinct species 
with entirely unbranched very lax culms, numer- 
ous rather long and very narrow basal leaves, 
and a narrow contracted panicle. The awns are 
long, with a long twisted column below the tri- 
furcation, and the lemma has a rather long very 
sharp callus of great penetrative power. The 
middle branch of the awn is stout and curved, 
and at maturity the curved awns of several fruit- 
ing lemmas become entangled with one another 
so that the grain is distributed in groups. This 
species are much more shallowly rooted than 
those of the preceding groups. It is in this 
district, confined to the deep sandy soil in the 
extreme east. 
The glumaris group is most widely spread. A. 
Benthami is confined to the Petrie series. A. glu-maris and 
A. vagans are dominant species in the typical phvllites 
grass community, and are common roadside species. A. 
queenslandica is more prominent on the upper part of rail- 
way embankments and the sides of cuttings. Some forms 
of these species resemble one another very closely in the 
field, but A. queenslandica can always be distinguished by 
its woolly lower internodes and A. vagans by its relatively 
short awns and glumes. The latter grass is very variable 
in stature and to some extent in habit, often spreading and 
more or less branched, particularly in the smaller forms. 
It is the commonest species of all. 
A. ramosa . occurs scattered over the schists area. The 
form allied to it mentioned above occurs in partially clear- 
ed greenstone country. A. gracilipes is an extremely 
slender plant with drooping inflorescence confined to the 
phvllites. A. calycina appears to be rare in the district. 
None of the species except possibly the young growth 
of intricata has any real grazing value. 
The genus Chloris has scarcely been mentioned in the 
general consideration of the grasslands. It is represented 
by six species: — Ch. divaricata R.Br., Ch. gayana Kunth,
