GRAMJNEjE. 233 



according to the expectations excited by its praises. Indeed, 

 A, vulgaris does not appear to be a grass so highly valued in Eng- 

 land as in this country. 



The 10 species of the " Geology," are far less abundant than 

 these 2, which are valuable for pasturage. 



Agrostis stolonifera, Fiorin Grass, is recently introduced. 



A. polymorpha. Huds. Fiorin Grass. A variety of A. alba, 

 and the same as A. decumbens, Muhl., according to Torrey. 



A. lateriflora. Mx. Grows 2 feet high or more, with swel- 

 ling knots or joints, branching, with lateral and terminal panicles 

 of rather dense flowers. 



A. sobolifera, Muhl., which is much like the preceding, is 

 probably to be added as one of our grasses about fields and borders. 



A. longifolia. Torrey. Is 2-4 feet high, erect, simple, 

 with leaves often 2 feet long, tapering into a fine extremity ; sheath 

 smooth ; panicle terminal and lateral, with compressed flowers. 

 Deerfield. 



A. sylvatica. Torrey. Is 2 - 3 feet high, erect, branched 

 and diffuse, with a slender filiform panicle ; glumes shorter than 

 the paleae, with awns longer than the flower. Hills of Berkshire 

 County. While it resembles A. lateriflora, and is A. diffusa, 

 Muhl., it is chiefly to be noticed for its spreading branches. The 

 other species are A. canina, W., clandestina, Spreng., tenuiflora, 

 Willd., Virginica, L. 



Polypogon. Des. 3. 2. 



Taken from Agrostis, and named from the Greek for many 

 beards ; as the glumes and the lower palese terminate in a bristle. 



P. glomeratus. W. Has an erect, compressed stem, and 

 close or not spreading branches, and a panicle, dense, inter- 

 rupted, and conglomerated ; bog meadows ; August and Sep- 

 tember.
