116 THE BOTANY OF WESTERN AUSTRALIA. 
plants which I suppose belong to new, or to such species of known, 
genera as may be interesting to botanists for their rarity, to florists for 
the beauty of their blossoms, or to the publie generally as characteristic 
of the country, beginning with the largest Australian Natural Order, 
the Leguminose. 
The country in the vicinity of Dundaragan, and near a spring called 
Palimarra, about twenty miles to the north-east, produces a remarkable 
Acacia, which grows to be a large tree with a trunk three feet in dia- 
meter; this species comes near the common Manna in botanical cha- 
racter, but the leaves are longer and narrower, and the seeds are much 
smaller ; the tree produces large quantities of a gum called dadjon by 
the natives, and which forms the principal article of food for them 
during the dry season. Another new species of Acacia, also allied to 
the Manna, but with broader and shorter leaves, grows in the York - 
gum forests, on the hills to the north of Dundaragan. The fine park- 
like scenery of the Bowes River district is principally produced by a 
species of Acacia closely resembling the common green wattle, but the 
leaves are greener, and the seeds and seed-vessels very different; the 
tree grows in groups or clusters, spreading by the roots; this species 
is slower in growth, and lives to a much greater age, than the green 
wattle. 
Acacia cyanophylla, and a Labichea with imparipinnate leaves, grow 
on all the limestone hills to the west of the Valley of the Lakes; this 
latter is perhaps the L. diversifolia of Meisner, in the * Plante Preis- 
sian,’ but if so it is a very different species from the L. lanceolata of 
Bentham, which Meisner supposes to be a variety of it. 
I observed, also belonging to the division of Leguminose, two fine 
species of Cassia, one with large glaucous imparipinnate leaves, another 
with similarly formed leaves, but having green leaflets ending in sharp 
points; both species grow on the Murchison. A species of Oxylobium 
with trifid leaves and flowers of a pale rose-colour when they first come 
out, but they soon change to white—a rare colour in Australian Legu- 
_ minose—grows abundantly by the road-side, about half a mile to the 
south of the salt springs called Colbourn by the natives. A very re- 
markable Jacksonia, with large and curiously-branched phyllodia, grow- 
ing in whorls, and bearing flowers in heads, is seen in abundance in a 
valley among the ironstone hills about four miles to the northward of 
Dundaragan. A very curious Daviesia, with broad plank-like leaves
