or tawny, bristly, spike-like inflorescence. Tt is probably 
of as much value as the cultivated millet or “panicum” 
( Set aria italica ), but is a much smaller plant. Eragrostis 
Cilianensis , known as “stink-grass” on account of its 
strong rather foetid odour, is common in places. 
Johnson grass occurs in a few places only, but where 
it does occur, it is a serious pest. Tt is a tall stout grass 
up to 6 feet high, with long stout brandling rhizomes 
which make it difficult to eradicate. 
There are two grasses which are commoner near build- 
ings than in cultivation plots. One is the annual prairie 
grass, Bromus unioloidcs, which appears in spring and 
early summer; the other is Eleusine indica (eoekspur 
grass) a more or less prostrate or suberect bright shining 
green perennial, which also appears in cultivation and by 
roadsides. 
The annual winter grass, Poci annua , so common in 
Brisbane, has scarcely been observed in this district. 
ROADSIDES. 
Along roadsides the commonest species are Digit aria 
didactyla , Cynodon dactyl on, Sporobolus capensis, 8. 
diander , Aristida glumaris , A. vagans , and in the water- 
tables, Eragrostis pilosa. 
GENERAL DISTRIBUTION OF SOME OF THE 
SPECIES. 
Some of the genera will now be considered in a 
general way with regard to their distribution in the dis- 
trict. The genus Aristida will be considered first. It is 
represented by eight undoubted species and one doubtful 
form, namely: — A. Benthamii Henr., A. calycina , R.Br., 
A. glumaris Henr., A. queenslandica Ilenr., A. ramosa 
R.Br., A. vagans R.Br., A. gracilipes Henr., and A. intri- 
cat a S.T., Blake (ined.) the doubtful form is probably 
merely a variety or habitat form of A. ramosa. All belong 
to the section Chaetaria , and are densley tufted perennials 
with tough wiry stems and more or less involute rather 
rigid leaves. Three distinct habit-types may be dis- 
tinguished: — 
(1) The glumaris type comprising A. glumaris, A . 
queenslandica, A. vagans and A. Benthamii. These 
species are erect, scarcely branched, with a divari- 
cate, usualy erect panicle (except^. Bentliami , 
where it is more or less nodding) with small to 
medium sized glumes, lemmas, and awns.
