 tall, sometimes taller; blades flat, 

 folded, or subinvolute, 2 to 4 mm. 

 wide; panicle ellipsoid, 5 to 15 cm. 

 long, the branches fascicled, rather 

 stiffly ascending, some naked at base 

 but with short basal branchlets, all 

 rather densely flowered; spikelets 2- 

 to 5-flowered, 3 to 4 mm. long; glumes

5. Puccinellia lemmoni (Vasey) 

 Scribn. (Fig. 81.) Perennial; culms 

 erect, slender, 15 to 30 cm. tall; leaves 

 mostly in an erect basal tuft, the 

 slender blades involute, 5 to 10 cm. 

 long; panicle pyramidal, open, 5 to
