In the differential phrase applied by Willdenow to this 

 species in the Species Plantarum, and adopted in the Enu- 

 meratio, as well as in Hortus Kewensis, the ray of the flower 

 is stated to be shorter than the disk, and the circumstance 

 selected as the main distinction between Villarsii and phi- 

 ladelphicum. But this character is obviously erroneous, 

 and has been probably assumed by Willdenow from a hasty 

 inspection of Bellardi's engraving of the plant, where some 

 of the flowers being represented in seed, when the pappus 

 extends itself beyond the ray, he has mistaken this for 

 the disk in flower. Bellardi expressly states, that the 

 flower is of the same structure as in Erigeron alpinum, 

 unifloruniy and acre, where the ray is as usual higher than 

 the disk. 



Introduced by Mr. Holboel in 1804. Called biennial by 

 Bellardi; marked as perennial in Hortus Kewensis. Gene-
