. I have specimens from the River Finke, N.T. (S. A. 

 White), and there is a similar one from Chambers' 

 Pillar in the Tate Herbarium, with stouter stems than the 

 parakeelya of the East- West Railway and much larger seeds 

 (1 mm. diam.), dark-coloured and concentrically granular; 

 anthers narrow-oblong. These are the true C. balonnensis. 



C. pleiopetala, F. v. M., although the number of petals 

 probably varies considerably, seems to be well distinguished 

 by its small amber-coloured smooth shining seeds, and I have 

 specimens with this character from Mount Gunson (Mrs. Beck- 

 with), and Koonowarra on Cooper Creek (S. A. White). From 

 C. calyptrata, Hook, f., which has also smooth shining seeds, 

 but larger and dark red, G. pleiopetala differs in its stouter, 

 probably perennial growth, much larger flowers, and numerous 

 stamens. 



G. pusilla, Lindl., varies much in size but is a smaller 

 plant with smaller flowers than G. polyandra. The colour of 

 the petals varies from purple to pure white. The stamens 

 are usually 7-10, but in an Ooldea specimen I found them to 

 vary between 6 and 12. Mueller says (Fragm. x., 68) that 

 he has sometimes seen the flowers with 20 stamens. The 

 seeds are minute (J mm. diam.), copper-coloured or almost 

 black, and concentrically granular, but in spite of the 

 wrinkling of the surface they shine with a metallic lustre. 



Cruciferae. 



Blennodia curvipes, F. v. M. Murnpeowie (Dist. C; H. 

 W. Andrew). "Sweet-scented and plentiful locally." 



Thlaspi cochlearinum, F. v. M. Murnpeowie (Dist. C; 

 H. W. Andrew). 



Stenopetalum sphaerocarpum, F. v. M. Tarcoola 

 (J. M. B.). Growing in sand; stems lying prostrate in a 

 circle. 



Lepidium leptopetalum, F. v. M. Eighty miles north 

 of Renmark (J. B. Cleland). The petals, longer than the 

 sepals, tapering into a point at the summit and twisted, at 

 least when dry, are practically those of the genus Steno- 

 petalum, with which this species forms a connecting link. 



Crassulaceae. 

 Grassida colorata, (Nees) Ostenf. (Tillaea acuminata, 

 Reader). Port Augusta; growing with C. Sieberiana. 



Leguminosae. 

 Leschenaultia divaricata, F. v. M. Redbanks, near 

 Murnpeowie. (Fruiting, August, 1920; H. W. Andrew). 

 The Tate Herbarium contains a flowering specimen from Anna 

 Creek, coll. M. Murray, April, 1885.
