occur). " A very pretty and very singular Convolvulus without stem." 

 On Leschenault's specimens Choisy founded his C. acaulis, which^ 

 according to Baron Mueller, is clearly the minute state of C. eruhescens. 

 To the above there should be added Eucalyptus diversifolia, described 

 bv Bonpland in 1813 from specimens grown from seeds gathered at 

 Kangaroo Island during Baudin's expedition. The specific name, as 

 only applicable to the young state of the plant, has been discarded 

 for that of santalifolia (see F. v. Mueller's " Eucalvptographia, Decade 

 8 "). (Tate, Proc. R.S., S.A., VI., 131 (1882-3)) [v). 



III.— LAND EXPLORATIONS (?r). 



Sturt. — We now pass onwards for a quarter of a century, until 

 Sturt's time.(.r) 



Let us turn to " Two Expeditions into the Interior of Southern 

 Australia during the Years 1828-31, &c.," by Captain Charles Sturt, 

 2 vols., 1833. (Southern Australia is not synonymous with our South 

 Australia.) 



In this work Sturt gives {inter alia) an account of his journey 

 " From Camden to and along the Rivers Morumbidgee and Murray, 

 across Lake Alexandrina to Encounter Bay." 



All his travels on his journey westward of lat. 141'^ were, of course, 

 in South Australia. They were along the Murray to its mouth. Very 

 few botanical allusions are contained in this work ; the map has notes 

 on the vegetation. 



Taking it out of strict chronological order we have — 



" Narrative of an Expedition into South Australia . . . during 

 the Years 1844-6, together with a Notice of the Province of South Aus- 

 tralia in 1847." By Captain Charles Sturt, 2 vols., London, 1849. 



This contains a " Map of Captain Sturt's route from Adelaide into 

 the Centre of Australia (lat. 24° 30' S.)," and is valuable for a list of 

 early names, and for its observations on the iiature of the country and 

 its vegetation. 



Vol. II., pp. 66-92, contains a Botanical Appendix by Robert Brown. 

 Sturt brought home about 100 species, many of them of especial interest, 

 and the Appendix, considering its author, is of course valuable. 



The explorer is commemorated in the genus Sturtia, R. Br. (in- 

 cluded in Gossypium, L.) ; Gossypium Sturtii, F. v. M. ; Hibiscus 



(r) Let me, at this place, invite attention to two South Australian bibliographical 

 works: — (1) Gill, Thoiiias, "Bibliography of South Australia." Published 

 for the Colonial and Indian Exhibition, 1886. 8^'0., pp. 118. Government 

 Printer, Adelaide. Most valuable. (2) Harris, G. Hope, " Geographical 

 Nomenclature of South Australia." These Proceedings, V., pp. 468-96 (1893). 

 A useful paper for reference, particularly as to the reasons why names were 

 given. 



(w) The Northern Territory is technically north of 26° N., but I have included 

 papers, &c., on Central Australia which are within the political boundaries 

 of North Australia, in the present sketch, as a matter of convenience. 



(x) A useful digest of Australian exploration, with special reference to South 

 Australia, will be found in Sir Samuel Davenport's Inaugural Address of the 

 S.A. Branch of the Geographical Society, Adelaide, 1886.
