Dasysloma pubescens Benth., in DC. Prod. 10: 520. 1846. "In Americae 

 sept, civitatibus orientalibus frequens." Type not verified, but descrip- 

 tion sufficiently distinctive. 



Dasystonm brachycarpa Small, Bull. Torr. Bot. Club 28: 452. 1901. "The 

 specimens on which this species is based were collected by the writer on 

 the slopes of Stone Mountain, Georgia, Sept. 6-12, 1894." Type seen 

 in Herb. New York Botanical Garden. Also collected by myself at 

 Stone Mountain, Pennell 4050, 5692. The short capsules of this plant 

 are quite within the normal range of variation of Aureolaria virgmica.
