(10) Agrostis alba L., Sp. PL 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.
