THE WEEDS OF NEW SOUTH WALES. 23 



Dipsacus sylvestris. This is a wild Teazel. I do not know of its occur- 

 rence in New South Wales. It is found in Tasmania. See Agricultural 

 Gazette, Tas. V., 176, for a figure. Ada Georgia, p. 403. 



Erechthiles valerianae folia. A beautiful plant, originally a garden escape 

 in Queensland, and found in the Dorrigo over ten years ago. Belonging to 

 the daisy family, its feathery seeds blow about. 



Erodium moschatum. An Alfileria of the United States and forming 

 .good pasture over a large extent of country on the Pacific Slope. In many 

 places it becomes a weed, and the fact that such a plant as this has been 

 proscribed, shows how difficult it is to deal with the weed question. 



Gaertneria discolor. (Belongs to the Loganiacese) . Franseria discolor 

 is a synonym. I do not know of its occurrence in Australia. Ada Georgia, 

 p. 458. 



Githago lychnis. This is generally referred to as Agrostemma Githago, 

 and is the " Corn Cockle." Its bad point is that its black seeds, about the 

 size of wheat, discolour and poison the flour. See p. 3. 



Helenium autumnal e. I know of no local record. Ada Georgia, p. 481. 

 Hypochaeris glabra. A close relation of //. radicata, which was originally 

 figured in the Agricultural Gazette for January, 1917. Its characters and 

 defects are similar. 



Iva xanthifolia. This is widely diffused and a great pest in the United 

 States. I know of no local record. Ada Georgia, p. 453. 



Iva axillaris. I know of no local record. See Ada Georgia, p. 451. 

 Jatropha multifida. Of interest only to Queensland at present. See 

 Bailey, p. 179. 



Jatropha curcas. Of interest only to Queensland at present. See Bailey, 

 p. 179. 



Jatropha gossypifolia. Of interest only to Queensland at present. See 

 Bailey, p. 177. 



Lantana Sellowiana. A garden form of Lantana, which, like the previous 

 three plants, has escaped from cultivation. See Bailey, p. 141. 



Lappula lappula is a synonym of Echinospermum lappula, a native plant 

 Leontodon hirtus. Allied to the Dandelion. In the Flora Australiensis, 

 in vol. 3 (1866), it was recorded from near Parramatta. Black, p. 100, re- 

 cords it from South Australia under the synonym Thrincia hirtus. 



Lepidium ruderale is one of the Pepper-worts, foetid and pungent to the 

 laste and smell when bruised, and already well established. 



Linum catharticum, " Purging Flax." I have no record of this in Aus- 

 tralia. 



Myagrum perfoliatum. I have no record of this in Australia, other than 

 the Victorian reference below. 



Oxalis corniculata. This small, yellow-flowered weed is all over Aus- 

 tralia, and is perhaps a native as well as a cosmopolitan. The aborigines 

 have long eaten the acidulous leaves to flavour their poor food. 



Plantago aristata. I have no record of this in Australia. See Ada 

 Georgia, p. 394. 



Pteridium aquilinum. The common Bracken fern. 



Rhus radicans causes severe irritation of the skin, even if not actually 

 touched. See the Agricultural Gazette for 1914, p. 611. 



Salsola kali-tragus. This weed has proved a great scourge in the United 

 States; a close relation is a native of Australia.
