These novelties enabled me already to establish seven new genera (Pseudo- 
morns, Basileopbyta, Phseoleuca, Tetracliaeta, Minuranthus, Psoraleopsis, and 
Rliytidosporum) . 
The descriptions, not only of almost all the new plants, l)at also critical 
notes and observations on the phytogeographicul range of the species already 
known, will be forwarded to Sir William Hooker before my departure for the 
interior, and will afterwards constitute, together with the scientific elucidations 
of such plants as may be added during the ensuing season from the yet 
botanically unexplored districts, the foundation of “ The Flora of Victoria.” 
That the vegetation of the southern parts of our province accords 
greatly with the Tasmanian Flora may be demonstrated by the fact that more 
than half of all the enumerated species are known to inhabit Van Diemen’s 
Land, amongst them many of great interest, wdiich had been considered as 
belonging exclusively to that island, some adding even new genera to the 
Flora of New Holland (Fagus Cunninghami, Bauera Billardierii, Tasmania 
aromatica, Weinmannia biglandulosa, Pleurandra monadeljihia. Ranunculus 
Gunnianus, Capsella Australis, Pittospoiuin bicolor, Rhytidosporuni pro- 
cumbens, Rhytidosporuni Stiiartianiim, Boronia dentigera, Eriosteinon verru- 
cosus, Corraea Backhousiana, Meionectes Browmii, Bossiaea horizontalis, 
Brachycome decipiens, Celmisia astelilolia, Scaevola Hookeri, Monotoca lineata, 
Lissanthe montana, Lissanthe ciliata, Prostanthera rotundifolia, Myosotis 
suaveolens, Wilsonia Backhousii, Gentiana Dieniensis, Sebaea albidiflora, Hakea 
microcarpa, Podocarpus montana, Phyllanthus Gunnii, Micranthea hexandra, 
Diplarrhena Moreea, Uncinia tenella, Triodontium Tasmanicum, and a great 
number of ferns. 
No numerical comparison with the Flora of South Australia and New 
South Wales has been instituted, as those localities are, not sufficiently exaniined 
which bear, perhaps, in this respect, as great a resemblance to the adjacent 
Colonies as the southern tract of this prov ince bears to Van Diemen’s Land. 
Still, there remains yet a considerable number of plants which impress 
on our vegetation a tyyie of peculiarity ; and I may be permitted, for this 
reason, to call attention to our remarkable syiecies ol Panax, resembling mainly 
those of the Molluccas ; to Trigoiutlla suavissima, as the only Australian 
clover ; to the species of Psoralea and to Crantzia, as connecting links with 
the American Flora ; to Pseudomorus Australasica, the indigenous mulberry 
tree ; to Myrsine Howittiana, nearer connected with the New Zealand species 
than with those of New South Wales ; and to the Alpine Anisotome glacialis, 
as a genus from Auckland and Campbell’s Islands. 
With regard to the Phytogeographia ot this country, it may be deemed 
worthy of notice that, in the arid steppes beyond the Glenelg River, the 
vegetation undergoes a remarkable change, and a large number of such plants 
as are common to Victoria, New South V ales, and Van Diemen s Laud, cease 
to exist, not even re-appearing farther to the westward, where the yihysical 
character of the country assumes once more equality or siimlanty to the 
eastern provinces. Others, again, extend the geograjihical limits ol certain 
o'enera or species which we thought to belong entirely to Western Australia, 
thus, for instance, Thomasia petalocalyx and Coleostylis Preissii range to fire 
148th meridian. . 
It may also be worthy of remark, that the order of Legummosaj prevails 
decidedly here, as in Western Australia, over all others ; and that the Com- 
positaj, far exceeding in South Australia, and almost throughout the world, 
any other groups, rank here as the second order. Both, taken together, show 
sucli eminent richness as to comprise nearly a fourth of all Dicotyledonar plants. 
The most predominant natural orders exhibit here, with regard to their number 
of species, the following series :—Le.guminosEe, Compositae, Myrtaceai, A gae, 
Filices, Cyperoideae, Gramineae, Musci, Proteacem, Orchidcm, Lpacridcce, 
Funo-i, Umbelliferm, Diosmeae, Liliaceae, Lichencs, Labiatae, Goodeniaceas, 
Scrophularin-cE, and Salsolacese.
