Notes made during the recent Expedition across the Northern Portion 

 of Australia, under the command of Mr. Surveyor Gregory ; by 

 Dr. F. Mueller, Colonial Botanist of Melbourne, and Botauist to 

 the Expedition. 



(Continued from p. 199.) 



JBuettneriacece of the latter part of the Expedition contain only a 

 new pink-flowering genus, allied to Waltheria, characterized princi- 

 pally by monoecious flowers, and a fruit consisting of two carpels 



(b 



it is rare enough on the sandstone 



table-land of the Gulf of Carpentaria. 



The beautiful genus Cochlospermum becomes increased by a tree of 

 much greater dimensions than Cochlospermum Meroneurum (C. Fra- 

 zeri ?), of the Victoria River, producing digitate leaves. It is very 

 distinct from O. Gossypium, according to the figure in your Miscellany.

longs to the section Ketmia, to which I am obliged to refer also the 

 Australian Fngosia, noticed in Sir T. Mitchell's last work, page 387, 

 although we may possess that genus, perhaps, in Hibiscus Huegelii, 

 Endl., from West Australia. Hibiscus Trionum is very common on ba- 

 saltic plains in the interior. The eight species of this collection are 

 all carefully described from a suite of living specimens ; form and co- 

 lour of petals, the columna, the disposition of the filaments, etc., afford- 

 ing as many beautiful characters for distinction of the numerous species 

 of this genus ; but all these marks are generally lost in drying the 

 plants. One mav be transferred, when fruit shall be obtained, to Abel- 

 moschus, although very distinct from A. albo-rubens, which extends as 

 far as Peak Range ; but Hibiscus splendens, belonging to the section 

 Ketmia, can never be removed from the genus, as done by various 

 writers. I send the description of eight Sida and Abutilons, and have 

 to add to the number of these and of Hibiscus as soon as I receive my 

 other notes. The rest of Tkalamiflora shows little of interest, perhaps 

 Byblis ccerulea excepted. , , . 



Myriacea form, I think, the most important part of my herbarium. 

 After watching the Eucalypti of tropical Australia day after day for 

 nearly sixteen months, I can confidently hope that m my ^f*T 

 of the species, I have not much erred from the truth ; and that th 

 two new systems of these trees, which I beg to recommend^ your
