39. Agrostis, Gen. pi. 111. (Gr amine*. J 



Cafrx 2-valved, 1 -flowered, valves acute. 

 Corolla 2-valved. Stigmata longitudinally 

 hispid or plumose.

 A. lateriflora ? Mich. 



Mexican Bent grass. 



Root creeping", jointed or soboliferous. One of my speci- 

 mens of this grass was sent tome by Dr. Muhlenberg", under 

 the above name, with A. lateriflora, Mich, as a synonym. 

 In his Descrip. Uber. Gr. he seems not to be certain of this, 

 and says "compare them." Pursh has both plants, with his 

 mark v. v., and his particular remarks on the A. lateriflora, 

 would seem to indicate a certainty in his opinion, of the dif- 

 ference of these plants. On the banks of the creeks in Jersey, 

 and this side of the Delaware. Common. Perennial. Sep- 

 tember.

Bastard Fiorin-grass. 



In the damp fields and borders of woods and meadows near 

 Woodbury, Jersey, not rare. Mistaken there for Fiorin-grass. 

 Dr. Muhlenberg- thinks this plant hardly different from the 

 A. stolonifera of Thouin . Perennial. June, July. 



4. A. culm erect striate smooth, geniculate at the 

 base, not stoloniferous, simple. Leaves linear*
