On shady rivulets, cataracts^ and in fissures of the rocks in 

 the Victoria and Serra Range and the Grampians. In South 

 Australiaj 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 flora, as Lepidobolus, Lhotzkya, Calectasia, nofpreviously 

 observed towards the east. 



DROSERACE^. 



3. Drosera angiistifolia. 

 (Sect. Arachnopus.) 



Stem foliate, simple, decumbent or adscendent; leaves 

 scattered, nearly sessile, long and narrow caudate, above and 

 along the margin glandulously pilose j racemes, either opposite 

 to the leaves or alternating with them, hardly of their length, 

 three-ten-flowered, covered Avith 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. 



POLYGALEJ?:. 



4. Comesperma polygaloides. 

 (Sect. Disepalum.J 



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 



In its characters approaching to C. semulmnj; in its habit 

 to C. calymegum.
