*Alopecurus geniculatus L. Sp. PL 60 [111. Fl. i: 149; Bot. Cal. 



2: 263]. 



The typical form with awns that are much longer than the glumes 

 is very rare in Montana. The following variety, with awns that 

 slightly, if at all, exceed the glumes, is more common. 



Montana: Lower Sand Coulee, 1891, R. S. Winiaiiis, 820. 



Alopecurus geniculatus fulvus (J. E. Smith) Scribner, Mem. Torr.

1467 ; Alopecurus aristulatus Michx. Fl. Bor. Am. i : 43 [Man. 



R. M. 407; Bot. Cal. 2: 263]. 



It is common in wet places, especially on sandy shores of lakes 

 and rivers, and around springs, and extends into the mountains to an 

 altitude of 2200 m.

Alopecurus occidentalis Scribner & Tweedy, Bot. Gaz. 11: 170; 



Alopecurus prate nsis alpesfris Vasey, Cont. U. S. Nat. Herb. 



3: 86; not A. alpestre Wahl. A. alpinus Port. & Coult. Fl. 



Colo. 251 [Man. R. M. 406] ; not Smith. 



It is a taller plant than A. alpinus, has longer spikes, larger 

 spikelets, 4-5 mm. long, and a short awn attached near the base of 

 the glume, and is conimon in wet meadows, at an altitude of 1500- 

 2500 m. It is an excellent hay-grass, and is without doubt worthy of 

 cultivation. 



Montana: Deer Lodge, 1895, Shear, 332 : Rydberg, 2113; Elk 



* Intermediate between this and P. aJpinum.
