 active and useful society. p^ ^^ Waugh. 



VERNdNIA (after Wm. Vernon, an English botanist 

 who traveled in North America). Compdsitte. Ieon- 

 WEED. A genus of nearly 500 species of perennial herbs 

 or rarely shrubs, with alternate, pinnately veined leaves 

 and usually purple or rose flowers borne in the follow- 

 ing species in terminal cymes. The genus is widely 

 scattered about the world, but is possibly most plentiful 

 in South America. The following species are native of 

 the United States, and are hardy perennial herbs of at- 

 tractive appearance, with rather large heads of purple 

 flowers in terminal clusters in late summer or early 

 fall. 



Heads not glomerate, several- tomany-tld. : involucre 

 of dry or partly herbaceous, much -imbricated bracts: 

 corolla regularly 5-cleft into narrow lobes; akenes 



■ 10-costate, with a truncate 

 and a cartilaginous, callous 

 pappus double (at least in 

 can species). Vernonias are 

 y culture in any good, rich 

 . being easily propagated by 



I. ffeads 50-70- flowered.
