Australian Plants. 7 
On shady rivulets, cataracts, and in fissures of the rocks in 
the Victoria and Serra Range and the Grampians. In South 
Australia, on the Onkaparinga and in the Lofty Ranges. 
This remarkable and beautiful species extends the geogra- 
phical limits of the genus Marianthus to the eastern portion 
of this continent, and is the only one hitherto known from 
‘beyond the boundaries of Western Australia. At the Gram- 
pians it is also accompanied with other features of the Swan 
River floraas Lepidobolus, Lhotzkya, Calectasia, not'previously 
observed towards the east. 
DROSERACEA. 
3. Drosera angustifolia. 
(Sect. Arachnopus ) 
Stem foliate, simple, decumbent or adscendent; leaves 
scattered, nearly sessile, long and narrow caudate, above and 
along the margin glandulously pilose ; racemes, either opposite 
to the leaves or alternating with them, hardly of their length 
three-ten-flowered, covered with short gland-bearing hairs ; 
segments of the five-parted calyx lanceolate, gradually narrowed 
upwards, about equal in length with the capsule, and half as 
long as the whitish petals; styles 3, divided to the base, its 
divisions filiform, incurved at the top; seeds egg-shaped, 
clathrate. 
On the moist gravelly margins of the Lakes on the Murray 
River towards Eustone. This is the first extratropical species 
of this section of Drosera with which we are acquainted. It 
approaches next to Drosera Finlaysoniana from Cochinchina. 
But this is only one of the many tropical forms of plants, 
which, transgressing the torrid zone, advance so far southerly 
as the Murray desert. 
POLYGALEZA. 
4. Comesperma polygaloides. 
(Sect. Disepalum. ) 
Smooth; leaves approximated, flat, narrow or linear-lan- 
ceolate, acutish, glaucous; racemes somewhat dense, purple; 
pedicels shorter than the flowers; lateral bracteoles about 
half as long as the intermediate one; lobes of the anterior 
sepal acutish ; carina gibbous at the top, hardly shorter than 
the wings. 
. In barren plains at the Avoca, Guichen Bay, and Encounter 
ay. 
In its chatacters approaching to C. emulum; in its habit 
to C. calymegum.
