TiETKENS. — " Journal of the Central Australian Exploring Expedi- 

 tion, 1889," under command of W. H. Tietkens. Government Printer, 

 Adelaide, 1891. 



This expedition went westerly from Alice Springs, passed the- 

 South Australian border and encircled Lake Macdonald, Western 

 Australia ; then went south-easterh% via Lake Amadeus, to the vicinity 

 of Charlotte Waters. 



The journal contains a valuable " List of plants collected during- 

 Mr. Tietkens's Expedition into Central Australia," bv Mueller and 

 Tate (from Proc. R.S., S.A., vol. 13, p. 94, 1890). 'Tietkens thus 

 traversed the northern part of the Larapintine region and added 58 

 species, including five new to science, to the Larapintine flora. 



The results of this expedition were also published in the following- 

 form : — 



" List of Plants collected during Mr. Tietkens's Expedition into- 

 Central Australia, 1889," by Mueller and Tate. Proc. R.S., S.A., XIII., 

 94-109. This was a collection of 250 species, eight being new to science, 

 together with a number of new records for the South Australian flora. 



Under the title " Supplemental Notes to tlie List of Plants collected 

 in Central Australia," Mueller, ibid, pp. 170-1, has interesting notes 

 on four species. 



For some particulars of the life of this meritorious explorer, who 

 has for some years been in the Public Service of New South Wales, 

 see Public Service Journal, Sydney, 1906.
