paid to the grasses of the county, these lists are necessarily in¬ 
complete with regard to this group. 
With the exception of a single one, all the species which we 
have collected appear to he described, although the range of a 
number is somewhat extended by the present records. The 
following are the more important of these: 
Panicum iennesseense Ashe. 
Setaria verticillata (L.) Beauv. 
Leersia oryzoides (L.) Sw. 
Sporobolus compressus (Torr.) Kunth. 
Cdlamagrostis Macouniana Yasey. 
Sphenopholis nitida (Spreng.) Scrib. 
Trisetum melicoides (Michx.) Yasey. 
Cynosurus cristatus L. 
Poa trimalis L. 
Glyceria pallida (Torr.) Trin. 
Bromus breviaristatus (Hook.) Buck. 
Brornus ciliatus laeviglumis Scrib. 
Agropyron Gmelini Scrib. & Smith. 
Elymus Macounii Yasey.
