 (8) Agrostis alba L., Sp. PL 63. 1753; ed. 2. 

 1: 93. 1762. Europe. Linnaeus' diag- 

 nosis is inadequate and his original 

 application of the name is uncertain, 

 but the specimen in his herbarium bear- 

 ing the name in his own script belongs 

 to the species for which the name has 

 been generally used by European and 

 American authors ever since. In recent 

 American works this species has been 

 called A. palustris Huds. But this name 

 proves to belong to the creeping species 

 with contracted panicle, the same as A. 

 maritima Lam. See U. S. Dept. Agr., 

 Bur. Plant Indus. Bui. 68: 25. 1905, 

 and U. S. Dept. Agr. Bui. 772: 128. 

 1920, for discussion of A. alba L. In the 

 second edition of the Species Plantarum 

 an undoubted reference to this species is 

 added to the original uncertain one. 

 Agrostis gigantea Roth, Tent. Germ. 1 : 

 31. 1788, described from Germany, is 

 this species according to W. R. Philip- 

 son, who examined the type specimen 

 borrowed from Berlin. (See Philipson,
