tuft, the slender blades involute, 5 to 10 cm long; panicle pyramidal, 

 open, 5 to 10 cm long, the slender flexuous branches fascicled, the 

 lower spreading, the longer ones naked on the lower half; spikelets 

 narrow, 3- to 5-flowered, the rachilla often exposed; 

 glumes about 1 and 2 mm long; lemmas narrow, acute, 

 glabrous, about 3.5 mm long; anthers 1.5 mm long. 9t 

 — Moist alkaline soil, southern Idaho and Washington 

 to Utah and California (fig. 115). 



6. Puccinellia maritima (Huds.) Pari. (Fig. 116). 

 Perennial; culms erect, rather coarse, 20 to 40 cm tall, 

 sometimes taller; blades 1 to 2 mm wide, usually be- 

 coming involute; panicle mostly 10 to 20 cm long, the 

 branches ascending or appressed, or spreading in anthe- 

 sis; spikelets 4- to 10-flowered; glumes 3-nerved, 2 to 

 3 and 3 to 4 mm long ; lemmas 4 to 5 mm long, pubes- 

 cent on the base of the lateral nerves and sometimes 

 sparingly between the nerves; anthers 1.5 to 2 mm 

 long. % — Salt marshes and brackish shores, Nova 

 Scotia to Rhode Island; Washington; on ballast, Phila-

 at base, 20 to 40 cm tall, some- 

 times taller; blades flat or more 

 or less involute, mostly 2 to 4 

 mm wide; panicle pyramidal, 

 loose, 5 to 15 cm long, the 

 branches fascicled, rather distant, 

 the lower spreading or finally 

 reflexed, the longer ones naked 



half their length or more; spikelets 4- to 6-flowered, 4 to 5 mm long;
