woods. 



84. * Festuca elatior L. Common on roadsides and borders of 



fields. 



85. Festuca siibulata Trin. In open thickets and borders of 



woods. A species of ver\' rapid growth, often reaching 

 a height of 5-6 feet after the first warm daj^s of spring.

(X).

streams, not common. 

 [/ 90. Glyceria occidentalis (Piper) comb. nov. First described as 

 Panicitlaria occidentalis in Piper & Beattie, Fl. N. W. Coast 

 59 (1915). It was originally collected by Hall in the 

 vicinity of Salem, where it is not infrequent along wet 

 ditches. Easily distinguished from G. leptostachya by 

 the acutish lemmas. So far as I know it has not )^et been 

 transferred to Glyceria, and the combination is accordingly 

 proposed. 



91. Glyceria paucifiora Presl. Common along streams and in 



wet places. 



92. Glyceria grandis Wats. With the last, but less common. 



93. Beckmannia erucaeformis (L.) Host. In ditches and wet 



meadows, not common. 



94. * Loliiim temidentum L. Rather scarce, but occasionally 



too abundant in grain fields. 



95. * Lolium miiltiflorum Lam. Abundant in dry soil almost 



everywhere. Apparently long confused with the next. 

 The species is very subject to teratological variations. 

 An apparent hybrid with Festuca elatior has been collected. 



96. * Lolium perenne L. With the last, but less common.
