Cylindrical heads with purple flowers, dispens- 

 ing- their seeds by the aid of a light globe of 

 pappus. Linnets, gold-finches and other birds 

 feed on the seeds ; and the larva of the plume 

 moth Pterophorus. with the painted lady 

 butterfly Vanessa, largely live on thistle heads. 

 The flowers are fragrant and rich in nectar, 

 which insects imbibe to abject intoxication.
