Australia, having been found at Renmark, Murray Bridge, 

 Pompoota, and quite recently within the City of Adelaide, 

 on wet ground along the north bank of the Torrens Lake, 

 near the University boatshed, where it often reaches a height 

 of nearly 2 m. The minute ligules of the corolla, which even 

 at the time of flowering are no longer than the pappus, give 

 it the appearance of an Erigeron, but the involucral bracts 

 are in 4-5 rows. Also established in Victoria and Queens- 

 land. Described in American floras as an annual, but often 

 survives at least two years here.
