Senecio Behhianus, Sond. and F. v. M. "Stiff Senecio." 

 (Compositae). 

 Gannawarra, near Koondrook, Victoria, H. B. Williamson (1915). 

 'Phis species appears to be rather rare, it being represented in the 

 National Herbarium previously only from two localities, namely, 

 Murray River, Victoria. F. v. Mueller, and Darling River, N.S. 

 Wales. Dallachy. 



Sisymbrium Irio, L. " London Kocket." (( Yuciferae). 



Near Anderson Street Bridge, Melbourne, W. R. A. Baker, 

 11/10/15. 



This introduced weed is a native of South Europe to the Caucasus, 

 and grows in a few localities in Great Britain, where it was prob- 

 ably introduced from Europe. The name is derived from the fact 

 that it sprang up in great abundance on the ruins after the great 

 fire of London. 



Trifolium pilulare, Boiss. "Syrian Trefoil.'" (Leguminosae). 

 Gunbower, Victoria, E. W Curtis. October, 1914. 



A native of Asia Minor and Syria. An exotic not yet sufficiently 

 established to he considered naturalized. It is loo hairy to be of 

 iimch use as a pasture plant. 



Xaxthorrhoea hastilis, R. Br. "Spear Grass Tree."' (Liliaceae). 



In Mueller's Second Systematic Census of Australian Plants, this 

 species is given from Victoria. There is a specimen in the National 

 Herbarium given as from New South Wales, near the Victorian 

 border, bul as there were no specimens from any Victorian locality 

 -Mine doubt existed as to its being a native of Victoria. Specimens 

 have, however, been received from Croajingolong (Oct.. 1915), which 

 belong to this species, and have the usual paler-yellow coloured 

 resin, instead of the darker ami reddish resin of V. australis. The 

 resin of the grass tree yields as much as 20-30, or even more, per 

 ■cent, of picric acid when treated with nitric acid, and seems likely 

 '" prove an important source of high explosives. The resin of 

 A. ImstiHs. though less valuable as a varnish than that of A. aus- 

 tralis, yields more picric acid, and hence it is of importance to 

 find the plant growing in Victoria. Many other cases are known of 

 typical N.S. Wales plants, which extend into Victoria down the 

 Easl coast, where the neighbourhood of the sea makes the conditions 

 more equable for plants of warmer regions.
