New Australian Plants. 63 



assistant, Mr. Wilhelmi, under the auspices of our Govern- 

 ment. For some of these novelties I remain indebted to 

 other gentlemen ; and I can only regret that I was not enabled 

 to bring on this occasion their merits more prominently before 

 the Institute in a fuller display of their kind communications. 



Only a few of the species are obtained by myself, princi- 

 pally salt bushes, — insignificant in their appearance, but 

 invaluable in the desert for the subsistence of sheep-flocks. 

 These were procured already, in 1851, near Lake Torrens, 

 a locality which quite of late attracted so much interest, 

 through Mr. Babbage and Mr. Groyder's enterprises. 



And when the discovery of an extensive saltwater lake, in 

 a position formerly assigned to the saline basin of Lake Tor- 

 rens, was hailed with universal delight, and when this new 

 approach to Central Australia in that direction augurs so 

 well for the future, we can be but animated with ardent 

 wishes for the welfare of the expeditions now engaged in the 

 geographical exploration of the interior of South Australia. 



I had, in distinguishing some of the more interesting of

 of them the names of members of the Philosophical Insti- 

 tute, not only as a token of personal respect, but also as an 

 appreciation of their services rendered to this society, and as 

 a slight acknowledgment of the disinterested manner in 

 which they fostered and cultivated science in this country. 



MONIMIE^. 



Hedycarya Pseudomorus. 

 (H. dentata var. Australasica, Sonder in Linnasa sxviii. p. 228 non Forster.) 



Leaves long petiolated, ovate or lanceolate, acuminate, 

 opposite and alternate ; stigma depressed, minutely um- 

 bonate ; carpels small, numerous, sessile, densely 

 crowded, yellow. 



In the forests from Cape Otway to Wilson's Promontory, 

 and probably also in New South Wales. 



I regarded this plant formerly as the type of a new genus, 

 and I am indebted to the venerable maecen, Sir William 

 Hooker, for information on its correct generic position. The 

 learned Dr. Sonder referred it to Hedycarya dentata from 

 New Zealand, -not having seen its fruit. It is not a little 

 surprising, that hitherto, of the numerous New Zealandian
