 Bracts hairless, with a long scariose acumen. 

 Lateral Div. of Cal. somewhat acuminate, not 

 ciliate on margin, p. 3— 7- Meadows and pas- 

 tures. I follow others in making the charac- 

 ters depend in part upon the p^ibescence, as 

 without it it seems impossible to distinguish 

 the species. Yet in our English plant I find 

 the Bracts sometimes quite smooth', and some- 

 times densely hairy on the back. The Scape,
