 POA GLU MARIS Triii. Mem. Acad. St. Pet. ser. 6. i. 379 (1831). 



Plant perennial, with a strong rootstock. 



Culm erect, robnst, smooth, striate, 1 to 2 feet tall. 



Leaves of radical tufts and from sterile shoots numerous, with broad, thick, 

 striate sheaths and flat, smooth, blunt-pointed blades, 2 to 4 lines wide and 3 to 8 

 inches long : leaves of culm usually but 1 above the base ; sheaths loose, smooth, striate, 

 carinate above, half open at the throat, half as long as the culm; blade flat or folded, 

 2 to 6 inches long; ligule 1 line long or less, crenulate and minutely ciliate. 



Inflorescence a closely flowered, contracted, oblong panicle 4 to 8 inches long; rays 

 in threes, fours, or fives, smooth, ascending or slightly spreading, unequal, 2 inches 

 long or less, divided and bearing numercas rather appressed, short-pedicelled spike- 

 lets. 



Spikelets oblauceolate, about 4 lines long, 3-to 5 flowered, usually with a rudiment; 

 empty glumes nearly equal, lance-ovate, acute, carinate, minutely scabrid, rather thick 

 for the genus, 3-nerved, 3 lines long; floral glume broadly ovate, acute, often denticu- 

 late near the apex, minutely scabrid throughout, pubescent on the keel and margins 

 below, 5-to 7-nerved, 2 to 2 J lines long; palet linear oblong, 4-toothed at the apex, 

 pubescent on the 2 keels; grain spindle-shaped, dark reddish brown, 1 line long. 



Plate LXXVII; a, part of branch with spikelets in position ; b, spikelet opened; 

 c, empty glumes; d, floral glume; e, palet opened. 



Alaska near the coast, east shore of Hudson Bay, Labrador, and Newfoundland. 

 This species is very plainly marked by the broad, blunt leaves and the large spikelets 

 with thick, scabrous glumes, which give it much the appearance of a Festuca. It has 

 not yet been found in California or Nevada, the reference in Bot. Cal. ii. 313 being a 

 mistake for Festuca conjinis Vasey.
