777^ WEEDS OF NEW SOUTH WALES. 



Amaranthus albus. There is a coloured figure of this in the Agricultural 

 Gazette for March, 1908, p. 234. 



Amaranthus artemisifolia is a slip of the pen for Ambrosia artemisifolia, 

 the so-called " Dunbible Weed " of the Northern Coast districts of NeM 

 South Wales, because it was found in that locality. For its occurrence in 

 South Australia, see Black, p. 105. It is a great pest in the United States, 

 and is stigmatised as " the universal weed of Ohio grain fields." 



Asclepias curassavica. Common in coastal Queensland, and gradually 

 working its way down. It is now at least as far south as the Manning. It 

 has showy flowers,^ and hence it is sometimes preserved for that reason. 



Avena fatua. A very bad pest in New South Wales and other parts of 

 Australia. 



Accsna ovina and A. sanguisorbce. The former is called " Sheep's 

 Burnet " by mistake, a name which belongs to Poterium sanguisorba, see the 

 Agricultural Gazette for April, 1898, page 360, and April, 1904, page 332. 

 As the Acwnas are native plants, and are already very abundant in the 

 eastern half of the State, the appearance of the plant in the list is not of 

 much interest to us. 



Bromvs secalinus. A grass, and a bad weed in wheat fields. 



Camelina sativa. This belongs to the mustard family, and is often 

 spread with dirty clover seed. In Europe it is cultivated as an oil seed. 

 It is an annual, and when it gets abundant in crops it becomes a nuisance. 



Cerastium vulgatum and glomeratum are by some authors reputed to be 

 synonymous. The name " Greater Burnet " attributed to the former in the 

 official list is incorrect. They are chickweeds, humble plants common in 

 gardens and waste places. 



Chenopodium album. This is an introduced salt-bush of little value, 

 which has spread over large areas in New South Wales, chiefly in waste 

 places. It has a disputed value to the poultry raiser, hence the name "Fat- 

 hen." See Agricultural Gazette, 1905, p. 474. 



CTiondrilla juncea had not made its appearance in Australia till it was 

 reported in New South Wales. See the Agricultural Gazette for 1918 T 

 p. 330. 



Crotalaria sagittalis. This is one of the leguminous poison-plants of the 

 United States, and I have drawn attention to it in the Agricultural Gazette 

 for 1901, p. 654. See Ewart, p. 24. 



Cucurbita perennis. This equals C. foetidissima, and is a native of 

 Mexico. Ada Georgia, p. 404, refers to it. 



Cretica hedypnois should be Hedypnois cretica. Recorded by the late 

 Mr. Betche and myself as an introduced weed in Proc. Linn. Soc. N.S.W., 

 xxix, p. 743 (1904). We know little of its detrimental properties. It is 

 undoubtedly spreading in New South Wales from Scone to Tenterfield 

 and Gunnedah. 



Crepis virens. It is often probably confused with C. japonica. It is 

 somewhat common on the tablelands of New South Wales. For its occur- 

 rence in South Australia, see Black, p. 104. 



Diodia teres. Belongs to the Kubiaceee. I know of no record of its occur- 

 rence in Australia. Ada Georgia, p. 400. 



Daucus brachiatus. This is a native plant, found all over the State, 

 whose burr gets into the wool.
