This species was discovered " on a rocky hill, two miles west of the 

 college " in Williamstown in 1817 by a pupil of Amos Eaton and 

 described in the second edition of Eaton's Manual of Botany in 1818. 

 The species was later found in Vermont, Pennsylvania and as far north- 

 west as Manitoba, but no additional stations were found in Massa- 

 chusetts, nor were botanists able to rediscover Eaton's station. In 

 1920 the writer had the good fortune to iind the plant growing in some 

 abundance at the above locality, probably the type station.
