 (10) Agrostis alba L., Sp. PI. 63. 1753; ed. 2. 1: 93. 1762. Europe. Lin- 

 naeus' diagnosis is inadequate and his original application of the name 

 is uncertain, but the specimen in his herbarium bearing 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. Bull. 68: 25. 1905, 

 and U.S. Dept. Agr. Bull. 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.
