 Plates XXXVIII. to XLIII. 



This list comprises 153 species collected by Capt. S. A. 

 White in the course of the expedition, during September and 

 October, 1916. It records two species which are believed to 

 be new to science, in the genera Panicum and Helipterum . 

 The other new records are: — 



For South Australia — Kochia pi ani folia , F. v. M. ; 

 Dicrastylis Costelloi., F. M. Bailey. 



For Tate's District C — Calamagrostis aemula , Steud. ; 

 Alopecurus geniculatus, L. ; Panicum divaricatissimum, 

 R. Br.; P. gracile, R. Br.; Heleocharis acuta, R. Br.; Blen- 

 nodia nasturtioides, Benth. : Gnephosis cyathopappa, Benth.; 

 Podolepis Lessonii, Benth. ; Helipterum pygmaeum, Benth. 



The country between Strzelecki Creek, Cooper Creek, and 

 the Diamantina was first explored by Capt. Charles Sturt, 

 and the plants collected were dealt with by Robert Brown in 

 a botanical appendix to vol. ii. of the "Narrative of an 

 Expedition into Central Australia during the years 1844-46." 

 The next collector in this district was A. C. Gregory, leader 

 of the Barcoo Expedition in search of Leichhardt. In 1858 

 he descended the Barcoo into South Australia and found it to 

 be identical with the Cooper Creek of Sturt. His plants were 

 enumerated in a report by Mueller. A. W. Howitt, leader 

 of the expedition for the relief of Burke and Wills, reached 

 Cooper Creek in September, 1861. In the third volume of his 

 "Fragmenta" (1863) Mueller mentions Dr. Wheeler and Dr. 

 J. Murray as botanical collectors in Howitt's expedition, and 

 several of their plants are there recorded by him. Dr. H. 

 Beckler was botanist to the Burke and Wills expedition, but 

 did not advance further than the Barrier Range. The new 

 records made in this district by Mr. Rodney Cockburri in 

 June, 1916, have been mentioned in these Transactions, xl., 

 459.

 notes. He writes : — "The term 'flooded ground' does not 

 mean that the ground was under water at the time, but indi- 

 cates that it is hard soil periodically subject to floods, either
