176 Alfred J. Ewart : 



Phalaris pakadoxa, L. (Gramineae). 



Menindie, N.S.VV., November, 1916. 



A new locality for this introduced plant. It is a native of the 

 Mediterranean Regions. 



Rosa kuuiginosa, L. (Rosaceae). "Sweet Briar." 



In a tall old plant, 6 ft. high, the tap root was found to have 

 descended 3 ft. in sandy soil, Avhile the largest lateral root extended 

 6 ft. 6 in., at an average depth of over 2 ft. In the case of this 

 plant, after cutting the stem nine inches below the surface, new 

 shoots appeared above the ground. Usually, however, lateral shoots 

 only arise from the stock a few inches below the ground, and with 

 such young plants a six inch ploughing usually cuts away the roots 

 capable of growth, those left in the ground dying. When the 

 ground is moist and the plants are dragged out with a horse and 

 chain, there is a greater possibility of leaving behind pnrts capable of 

 developing new shoots, but th'^se can be easily de.stroyed witli a mattock 

 when they appear a few months later. 



vSlSYMBRiUM ori^:ntalk, L. (Cruciferae). " Indian Hedge Mustard." 



Foreshore, Geelong, H. B. Williamson, No. 1449, December, 

 1910. Northcote, W. R. A. Baker, January, 1911. Bank of Yarra, 

 Anderson Street Bridge, W. R. A. Baker, January, 1913. War- 

 racknabeal, E. T. Lukey, November, 1913. 



It is a native of Europe and Asia, now widely spread in Victoria. 

 This plant is very easily confused with Erysimum repandum, and 

 in some cases records of E. repandum really refer to Sisymbrium 

 orientale. It is a weed of waste places, but spreads in pastures and 

 cultivated ground if neglected. 



Solanum hkterandrum, Pursh. (Solanaeeae). "Pincushion 

 N^ightshade." 



Bute, S. Australia, per Professor Osborn, March, 1917. This 

 North American weed is already recorded as a naturalised alien in 

 Victoria and New South Wales, and is now evidently establishing 

 itself in South Australia. 



Staticr Thouini, Vis. "Thouin's Sea Lavender." 



A garden escape at Wycheproof. 



A native of the Mediterranean Regions. Coll., Rev. W. W. 

 Watts, Dec, 1916.
