 Hitchc. in Gray Man. ed. 7, 139 (1908.) — As pointed out by Hitch- 

 cock in Am. Journ. Bot. 2: 304 (1915) the specimen of Avena pennsyl- 

 vanica in the linnean Herbarium is identical with the species that has 

 been called S. palustris and consequently as the older specific name 

 must replace palustris.

 As the specific combination has been altered a new combination is 

 required in transferring the variety.
