"the State. S. humilis is essentially northern in its habitat.. 

 Puzzling forms, almost intermediary, occur on Kangaroo 

 Island, where Tate records the existence of both species. 



Compo SITAE. 



Helipterum floribundum, DC, var. Sturtianum, Benth. 

 Dublin scrub (H. H. D. Griffith) ; Gawler Ranges (S. A. 

 White) : Telowie : Pirie : Karoonda : Warramboo. This is the 

 form with straw-coloured outer bracts of the involucre and 

 pappus-bristles united only at base. The spreading snow- 

 white inner bracts of this ' 'everlasting" are a marked feature 

 in many parts of the Murray Scrub and Eyre Peninsula. 

 The type, with all the bracts white and the pappus-bristles 

 dilated and united in their lower halves, is found chiefly 

 in our Far North — -Mount Lyndhurst, Oodnadatta, Tar- 

 coola, Mount Gunson, Gawler Ranges, Arkaringa, 

 Everard Range, River Finke. In these Transactions, 

 xxxvi., 23, pi. ii., it was sought (I now think unneces- 

 sarily) to distinguish this form as var. t-ubulipappwm. The 

 specimens vary in size, and there are small intermediate 

 forms from the Murray and Wallaroo, with all the bracts 

 white but the pappus-bristles united only at base. H. corym- 

 biflorum, Schlecht. This beautiful little plant often covers 

 the ground along the banks of the Murray with a carpet of 

 'white everlastings," as it also does in many of our northern 

 districts. At Melrose it grows on the flats among the box- 

 gums. 



Athrixia tenella, Benth. Specimens from Edilillie have 

 the upper part of the stems more or less clothed with erect 

 or spreading bracts similar to those of the involucre. This 

 character shows an approximation to the Western Australian 

 A. Croniniana, F. v. M., but the pappus is normal. 



Cratystylis conocephala, S. Moore, in Journ. Bot., xliii., 

 138, aim. 1905 (Olearia conocephala, F. v. M. ; Pli/chea 

 conocephala, F. v. M. ; Stera conocephala, Ewart et Rees). 

 Common near Murat Bay and inland towards Chillundie. 

 The conical heads are very fragile, finally falling from the 

 branchlets and the bracts separating from the receptacle. The 

 flowerheads seem to be constantly semi-dioecious or dioecious, 

 the bisexual (or male ?) corollas swollen towards the summit 

 by the fertile, connate anthers, the female corollas cylindrical 

 with the anthers abortive and free. (See pi. vii.) The 

 pistil of the bisexual flowers appeared perfect, but it was too 

 early in the season (November 11) to make certain on this 

 interesting point. A densely-branched, compact shrub about 

 1 m. high, called locally '"Bluebush," and so closely simulat- 

 ing in habit the other Bluebush of our northern and north- 

 eastern country (Kochia sedifolia, F. v. M.) that at a short
