192 REPORT OF THE VICTORIAN GOVERNMENT BOTANIST. 
work devoted to original discoveries, and written in a language com- 
mon to science of all nations, is almost completed. The fourth vo- 
lume of the universal work on the plants of Australia is, through my 
aid, under the rare advantages attainable in the great national institu- 
tion of Kew, just completed by the President of the Linnean Society, 
and comprises the Orders of Corolliffore. Extensive preliminary re- 
searches have been carried on already for the fifth, sixth, and seventh 
volumes ; to which, finally, a supplement is to be added. To promote, 
by further field researches, the objects of this large work, on which all 
subsequent medieal, technological, and rural observations in reference 
to the native Australian vegetation must rest, I visited, during the 
past spriug, one of the most important tracts of West Australia. 
Finally, also, the great task yet remains to be performed of tracing out 
more completely the relation of geology to the distribution of the plants 
existing as well as passed away,—a line of researches for which excel- 
lent geographical and geological maps are annually affording more fa- 
cilities. Mr. Dallachy continues sedulously to collect, both for the 
Garden and the Phytographie Museum, in the north-east part of 
Queensland. 
The following are the genera which, since the issue of my last Re- 
port, by local independent researches, have been added to the system 
of Australian plants :— Dillenia, Cakile, <Aldrovanda, Gomphandra, 
Connarus, Strongylodon, Salacia, Caryospermum, Casearia, Cucurbita, 
Cnanthe, Antirrheea, Lasianthus, Ophiorrhiza, Geophila, Aniseia, Ery- 
cibe, Ichnocarpus, Ceropegia, Bassia, Chrysophyllum, Thunbergia, Grap- 
tophyllum, Dischisma, Cylicodaphne, Cinnamomum, Plecospermum, Taxo- 
trophis, Hyrtanandra, Nepenthes, Apostasia, Cirropetalum, Pogonia, 
Spathoglottis, Dracena, Bambusa, Centotheca, Angiopteris, Marattia, 
Deparia, Isoetes ; and the horia. genera new to phytography :— 
Fitzgeraldia, Pagetia, Davidsonia, Thespidium, Eleutheranthes, Thozetia, 
Carnarvonia, Darlingia, Helmholtzia, Corynotheca ; by which means re- 
presentatives of Connaree, Samydee, Selaginee, Nepenthee, and Aposta- 
siacec are added to the Australian flora. The following are additions to 
the list of Australian trees published in the volume of the Intercolonial 
Exhibition :—Melodorum Maceraei, Pittosporum rubiginosum, P. venu- 
losum, Eriostemon squameus, Sterculia laurifolia, Sloanea Woollsii, S.
