that the two constitute one species, coalescing about the border 

 of South Australia and Victoria. Bentham appears to me to 

 sanction the union when he writes (PI. Aust., iii., 586) that 

 the leaves of G . aculeata are 'very rarely smooth or nearly so.' r 

 They are of equal date, but G. aculeata has priority of paging. 

 The arrangement for South Australia would therefore be : — 



G. aculeata, R. Br. (approaching the type), Bordertown. 

 Var. laevis, Port Elliot; Murray Lagoon, K.I. ; Caloot, near 

 Mannum ; Coonalpyn ; Sherlock ; Ardrossan scrub ; Pitoairn 

 Station, near Nackara; Beetaloo ; Melrose; Telowie Gorge; 

 Telowie scrub ; Aroona ; Gawler Ranges. 



[Since writing this I have received from Hawker (Miss 

 Reed) a typical specimen of C. aculeata as regards the 

 scabrous leaves, which are also conspicuously decurrent ; 

 flowers 10-12 in head; pappus-bristles about 12, barbellate 

 in the upper part only.] 



Olearia picridifolia, Benth. Yumali (S. A. White). See 

 these Trans., xxxv., 2. 0. pimeleoides, var. minor, Benth. 

 Yumali (Dist. T; S. A. White). 



Helichrysum retusum, Sond. et F. v. M. Yumali (Dist. 

 T; S. A. White). H. ferrugineum, Less. This rather rare 

 shrub, which in our specimens has always a white (not rusty) 

 tomentum, was found on the Glenelg River and at Lake 

 Edward, near Glencoe. 



Calocephalus Dittrichii, F. v. M. (pi. viii.). The drawing 

 was made from a specimen in Mr. Walter Gill's herbarium, 

 collected on Coward Springs Mound, November 19, 1891. The 

 type came from near Charlotte Waters, N.T. It is given for 

 District C in Tate's Flora, but there is no specimen in the 

 Tate Herbarium. Professor Ewart says that Mr. Gill's 

 specimen agrees well with the type in the Victorian National 

 Herbarium, and it is certainly the same as a named specimen 

 which Mr. J. H. Maiden kindly sent me from the National 

 Herbarium of New South Wales, and which was collected by 

 Max Koch near Catt Springs, Murnpeowie, in September, 

 1898. The species is recorded by Moore for the northern 

 interior of New South Wales. The original description was 

 published by Baron von Mueller in Uhlworms Botanisches 

 Centralblatt, xxvii., 300 (1886), and as this periodical is very 

 rare, if not inaccessible, in Australia, the diagnosis, kindly 

 supplied by Professor Ewart, is here given in full : — 



"Calocephalus Dittrichii ( Myriocephalus Dittrichii, 

 F. v. M. Coll.). Annual, woolly-tomentose, neither tall nor 

 much branched ; leaves scattered, linear, blunt, nearly flat or 

 somewhat channelled, slightly broader at the base; glomerules 

 rather small, terminal, solitary, depressed-globular, the
