III. Geococcus pusilla (?). 10/9/98, &c. 



Plentiful in Willovvie township. This plant was dealt with in 

 detail by the late Prof. Tate in his paper on " Dimorphism in 

 Cruciferse," read before this Society on October 4, 1898. 



IV. Capsella pilosula. 

 Tn this plant the leaves, as the plant grows here, show great 

 divergence from the ohovate form. They often approach to 

 lanceolate, and to oblong, and may be entire, slightly notched or 

 almost pinnate. The leaf form seems to vary with the situation 

 of the specimen, and also with its nutrition. 



2. Order Malvaese. 



Abutilon otocarpum. 

 I discovered about a dozen plants in one small area in March, 

 1898. They reappeared in the same place in '99. They were 

 then eaten off by travelling stock and since then have not grown. 

 This species is given as not nearer than the Cooper district. 



3. Order Zygophylleae. 



Zygophyllum ammophilum. 28/10/00, &c. 

 Occurs plentifully in overflowed areas in wheatfields. Not 

 widely distributed, but not rare within certain areas. Given for 

 the Districts C, W, and M. It thus occurs east, west, and north 

 of this locality, and on considerations to be mentioned later may 

 be taken as fairly common in District S. 



4. Order Amarantaese. 



Ptilotus alopecuroides. 29/9/99, &c. 



Fairly abundant in the neighborhood of Willowie and sur- 

 rounding plain. Given for all districts around this one (l!^). 

 The plant occurs in all favorable situations, and should be in- 

 cluded as for District N. 



5. Order Urtieaeese. 



L'RTICA in CIS a. 



Near all townships, in gardens and stock yards, and luxuriantly 

 in places on the Willowie Station, near Melrose. Only given for 

 southern parts of the State. Most probably introduced from the 

 south with garden or field seeds, and in the fleeces of travelled 

 sheep. 



6. Order Casuarinae. 

 I. Casuarina quadrivalvis. 29/9/00 



Commonly in Pekina Range, west of Orroroo ; not hitherto 

 recorded for District N. Also on Mount Ptemarkable.
