*Lactuca scariola, L. "Prickly Lettuce." Berri; numer- 

 ous but not widely spread (H. W. Andrew). First record for 

 South Australia, although it was observed some years ago in 

 the Eastern States. — Europe. 



^Taraxacum officinale, Weber. "European Dandelion." 

 Common on roadsides at Mount Gambier. 



*Leontodon hispidus, L. "Common Hawkbit." Millicent, 

 near drains. First record for South Australia. A European 

 and West- Asiatic weed. 



*Senecio elegans, L. "Purple Ragwort." This showy 

 Cape plant, already recorded for Robe, grows numerously at 

 Beachport on sandhills close to the sea, beneath the shelter of 

 Acacia longifolia. 



*Scorzonera laciniata, L. Paddock at Mile End goods 

 sheds (H. W. Andrew). Previously recorded from Collins- 

 wood. 



*Cirsium arvense, Scop. This troublesome weed has been 

 found growing in patches near Mount Gambier. 



* Chrysanthemum Parthenium, Bernh. "Feverfew." 

 Roadside near Mount Barker (H. W. Andrew). Not previously 

 found wild in South Australia, but recorded for Victoria 

 in 1893. 



*Carthamus glaucus, Bieb. ( K entrophyllum glaucum, 

 Fisch. et Mey.). Naracoorte (H. W. Andrew). Occupying 

 large areas in this district. Distinguished from C ' . lanatus, L. 

 (K. lanatum, DC), by its smaller flower-heads, the inner 

 involucral bracts all entire, and none of the middle ones 

 contracted near the summit, and then dilated into a small 

 appendage, as in 0. lanatus, flowers purple instead of yellow, 

 and smaller achenes. A prickly weed of the eastern Mediter- 

 ranean region, which does not appear to have been previously 

 recorded in Australia. It has, however, been established in the 

 South-East for some time, because a single head was sent to 

 me from Bordertown in 1909.
