MEMOIRS. OF ,THE NEW YORK BOTANICAL GARDEN. 57 



* Festuca vallicola. 



Rootstock filiform ; innovations extravaginal, few and sieniier : 

 culm 6-10 dm. tall, slender, seldom much over i mm. in diameter, 

 strict, generally ver}^ light-colored and shining, somewhat striate 

 above; sheaths striate, closely embracing the stem, 6-12 cm. long, 

 generall}- shorter than the internodes ; ligule short, rounded at the 

 apex, somewhat decurrent ; blades filiform, involute, the basal some- 

 times I dm. long, those of the stem 4-8 cm. long ; panicle narrow, 

 about 5 cm. long, the lower branches sometimes 3 cm. in length ; 

 spikelets 4-7-flowered, 8-10 mm. long, on pedicels 1-3 mm. long; 

 empty glumes unequal, the lower glume 2—3 mm. long, very narrow, 

 almost subulatCj strongly keeled, the upper one lanceolate, 4-5 mm. 

 long, 3-nerved, acuminate; flowering glumes about 5 mm. long, 

 ovate-lanceolate, indistinctly 5-7-nerved, almost smooth or minutely 

 scabrous, tipped with an awn 2-4 mm. long ; palet very narrow. 



This has generally gone under the name of F. rub?'a, but it is dis- 

 tinct, at least from the Scandinavian plant. The latter is quite often 

 lufted, has larger spikelets, broader glumes, looser sheaths, broad 

 flat stem-leaves, and a much stouter stem. F. vallicola, so far as I 

 know, never forms tufts or bunches, and the innovations are few. I 

 doubt if F. rubra is found at all in the Rock}- Mountain region. All 

 specimens so named which I have seen from the northern Rockies 

 belong to the present species. F. vallicola grows in wet meadows 

 in the valleys of the mountain regions at an altitude of 1500-2000 m.
