Ooldea, July, 1920 (Mrs. Daisy Bates). Very different 

 in appearance from the typical form, with long pink or white 

 rays, so frequently cultivated in gardens. There are two 

 similar specimens in the Tate Herbarium collected by R. 

 Helms in the Fraser Range, W.A., October 4, 1891, and 

 labelled "H. Troedelii, F. v. M., var. patens, A. J. Ewart." 

 In the Proc. Roy. Soe. Vict., xxii. (n.s.), part 1, 15 (1909), 

 where the varietal name is published, the localities given 

 are "Mount Lyndhurst, M. Koch, No. 1644, 1899; Fraser 

 Range, W.A., R. Helms, 1891." This plant differs from 

 H. Troedelii in its glabrous character, the shape of the 

 involucre and its radiating laminae, the greater number of 

 flowers in the head, the more numerous pappus bristles, 

 penicillate and golden at the summit and not united in a 

 tube. In all these respects it agrees with H. roseum. It is 

 probably the form of that species "capitulis parvis" men- 

 tioned by Diels and Pritzel (Fragm. phyt. Aust. occid. 628) 

 as having been collected on the Victoria Plains, W.A. They 

 also observe that H. roseum is very variable in size and 

 colour of flowers. The varietal name is not appropriate in 

 respect of H. roseum, but it must be retained under art. 48 

 of the Vienna rules. 



H. Humboldtianum, (Gaudich.) DC. Ooldea (J. M. B.). 

 First record for South Australia of this species, of which 

 the type was gathered in Western Australia. It cannot be 

 the closely allied species H. Haigii, F. v. M., described from 

 specimens collected near Eucla, because our plant has 

 pubescent achenes and only the outer involucral bracts are 

 woolly. It is a handsome everlasting, the inner bracts having 

 small obtuse golden radiating laminae. The number of 

 flowers in the head is 12-14 and the pappus-bristles 14-15. 



H. Tietkensii, F. v. M. Eighty miles north of Ren- 

 mark (J. B. Cleland). Flowers in head only 6-7; pappus- 

 bristles 18-20. 



Senecio dryadeus, Sieb. The existence of this species in 

 South Australia seems to be only an assumption. Bentham 

 in the Flora Australiensis quotes in his list of localities : 

 "South Australia. Loddon River, F. Mueller." This river 

 is of course in Victoria, and is situated more than 150 miles 

 east of our border, as the crow flies. Mueller, in his 1st 

 Census of Australian Plants (1882) gives S. australis, A. 

 Rich. (S. dryadeus, Sieb.), for South Australia. In his Key 

 to the system of Victorian plants (1887-8) he locates S. 

 dryadeus in his SW District, which extends as far west as 

 "the vicinity of the Glenelg River." There is no mention of 

 the species in any of Tate's lists of South Australian plants 

 until the year 1883, when in his "Additions to the Flora of
