rather attractive plant, with large white-rayed flowers, the latter 
possessing white flowers of small size, and exuding a glutinous 
secretion from both stems and leaves. In the open glades occur 
large patches of Leptorrhynchus, Waitzia, and at rarer intervals 
Helipterum floribundum, also the little yellow-flowered H. Jes- 
senit, H. moschatun is also partial to such localities, but at still 
rarer intervals. Hlachanthus pusillus is another small annual 
composite peculiar to some loamy soils, generally growing in 
patches. Cassinia arcuata occurs as a tall shrub in a few places, 
but is fast dying out. As we get nearer to the desert country, 
the scrub thickens, and mallee scrub proper is entered. The soil 
for the most part still retains its clayey nature, resting ona 
stratum of limestone gravel, with an occasional pine rise to break 
the monotony. Deep depressions are numerous, and these gener- 
ally terminate in a run-away hole. The land being suitable for 
wheat-growing, is now, nearly all, brought under cultivation by 
means of the mallee roller and stump-jump plough. Here may 
be found some of the most typical plants of this region, such 
as Myoporum platycarpum, a small tree, and, at rarer intervals, 
M. deserti, a bushy shrub. Hriostemon pungens, and the pink 
flowered EH. diformis, Bertya oleifolia, Dodonea bursarifolia, 
Cassia eremophila, Acacia spinescens, A. rigens, A. calamrfolia, 
A. acinacea, A. montana, A. hakeoides, A. salicina, A. trineura 
(a species with seented wood), <A. Oswaldi, near Lake Hind- 
marsh, A. rachybotrya on the sandy rises; a species regarded by 
Baron von Mueller as a variety of A. montana, described by Mr. 
Reader, a local botanist, as A. glanduligicarpa, and A. sclerophylla. 
Another species discov ered by the writer has yet to be identified. 
The late Baron von Mueller regarded it as a distinct species, 
but deferred naming it until fruits were forthcoming, which, un- 
fortunately, could not be procured in time. Mr. Luehmann con- 
siders it to be a variety of A. lineata (A. runciformis of the 
Census), or of A. montana. The Myrtaceous order is represented 
by Lucalyptus gracilis, E. uncinata, E. incrassata, E. oleosa, and 
L. Behriana, all passing under the general designation of Mallee 
scrub. The last-named, being of a larger growth than the others, is 
locally known as the Bull Mallee. Varieties of #. gracilis and LE. 
tncrassata have been noticed bearing pink or scarlet flowers. 
Choretrum chrysanthum is a bushy shrub sparsely distributed 
throughout the district, rendered conspicuous amongst the serub 
by the peculiar hue of its leafless branches, either a pale green, or 
sometimes an almost golden yellow, making a striking contrast 
with the sombre-hued foliage of the scrub with which it is associ- 
ated. It may not be generally known that this plant, particularly 
the young shoots, possess an acidity which is very acceptable to the 
traveller who may happen torun short of water. Another species 
having the same properties, C. glomeratum, is a straggling shrub
