TRIANDRIA— DIGYNIA. Amostis. 89 



ft' 



strata stems. Leaves narrow, acute. Panicle much branch- 

 ed, generally spreading, of innumerable, solitary, erect, 

 sm^ijlo'wers. Cal. roughish, often coloured. Cor. most 

 frequently pale, or whitish. Seed very minute. 

 Agrostis, as generally understood by authors, is justly said 

 by Mr. Brown to be an artificial genus, and therefore I 

 should scarcely hesitate to admit Trichodium of Michaux 

 and Schrader, as an artificial separation from it, differing 

 only in having a single valve to the corolla. Such Schrader 

 found to be the case with A. canina, but I do not, and 

 therefore we have nothing to do with Trichodium in a 

 British Flora.
