 FESTUCA SUBULATA Bong. \cg. Sitcli. IT."? (IS.'^l). 



Plant perenniiil, tufted, with numerous radical leaves and sterile shoots. 



Ciihiis erect, siin])le, nearly smooth. 13 to 3 feet tall. 



Ijinres of radical fults and of sterile shoots with rather thin, ehartaceons, smooth 

 sheaths and involute, scaltmus blades (> to 12 inches long, usually deciduous to the 

 sheath: leaves of the culm usually but 1 above the base; sheath striate, nearly siuooth, 

 close, open at the throat; blade flat or involute, 3 to 5 inches long; ligule nearly obso- 

 lete. 



Inflorescence a loose, open, flexuous panicle 4 to 7 inches long; rays mostly in 

 twos at the .'5 to 7 nodes of the rachis, scabrous, flexuons, usually contracted above, 

 somewhat s])reading or rcilexcd in age below, spikelet-bearing mostly beyond the 

 miildle. 



Spilcelets rather turgid, 3- to 5-flowercd, (> In 7 lines long; first em])ty glume nar- 

 rowly ovate, barely acute, his])id on the keel, 3 lines long; seccmd eni])ty glume broadly 

 lanceolate, acute, convex, hispid on tlie keel,3-nerved, t lines long; lloral glume lance- 

 ovate, acute, the points involute-subulate, convex, scabrous, 5-nerved, 5 to 6 lines 

 long; palet lance-linear, bifid at the a])ex, minutely i>ubescent on the keels, J line 

 shortei- than the glume. 



Plate XCII; a, spikelet spiead somewhat; b, first empty glume; c, second 

 empty glume; d, floi-al glume; e, palet not opened, young stamens showing beh»w. 



It may be distinguished from Festuca ticabrelln Torr. by its larger and looser ]>an- 

 icle, and larger si)ikelets with subulate pointed glumes. This description is based on 

 specimens from Alaska, which, however, do not wholly agree with the description of 

 Bougard.
