Vernonia georgiana is easily distinguished from V. oligophylla, 
with which it grows, by the much narrower leaves, fewer flowered 
involucres (flowers about 28 in V. georgiana, more than 40 in V. 
oligophylla) and by the less spreading and much shorter outer involu- 
cralscales. It is known to me only from the one locality.
