Griffiths 6645, 6649; Madera Co., Congdon; Hockett Meadow, Hitchcock 3468; Farewell Gap, 

 Purpus 5151; Whitney Meadows, Coville $ Funston 1676. In Nevada at Glenbrook, Lake 

 Tahoe (Hitchcock 3198, 3205). In Oregon in the Crater Lake region (Coville 4" Leiberg 392, 

 Coville 1458, Hitchcock 3044, 3059). 



6. G. elata Hitchc. n. comb. Culms erect, smooth, succulent, 3 to 6 feet high; 

 sheaths scabrous; blades flat, usually 3 to 5 lines or sometimes only 2 lines 

 wide, scabrous; panicle large and diffuse, becoming oblong, 6 to 12 inches 

 long, the branches naked below, the lower usually reflexed at maturity ; spike- 

 lets l l /2 to 2 l /2 lines long, oblong or ovate-oblong, usually 6 to 8-fiowered; 

 glumes broad, obtuse, much shorter than the lower lemmas, nerveless, the first 

 about 1/2 line long; lemmas firm, obovoid, obtuse or acutish, prominently 7- 

 nerved. This may be only a form of G. nervata Willd., but the California 

 specimens differ from the eastern and northern representatives of that species 

 in being taller and more succulent, and in having wider blades, more oblong 

 panicle with the lower branches often reflexed, and larger spikelets. 



Wet meadows, springs, and shady moist soil in woods, in the Coast Ranges 

 to the Bay region, in the Sierra Nevada, and the high southern mountains; 

 north to British Columbia and east to Idaho.

60. PUCCINELLIA Parl. 



Spikelets several-flowered, terete, in open or narrow panicles. Glumes un- 

 equal, short. Lemmas rounded on the back, obtuse, firm, obscurely nerved. 

 Perennial grasses with pale spikelets; growing along the seacoast or in alka- 

 line soil, differing from Panicularia chiefly in the obscurely nerved lemmas. 

 Species 14, in northern extratropical regions of both hemispheres. (Prof. Bene- 

 detto Puccinelli, an Italian botanist.) 

 Panicle open, the branches spreading. 



Leaves mostly in a short radical cluster; panicle usually less than 4 inches long

1. P. lemmoni Scribn. Culms slender, 6 to 15 inches high; blades short, 

 filiform, mostly basal, smooth, involute ; panicle 2 to 4 inches long, becoming 

 open, the branches spreading ; spikelets 2^2 to 3 lines long ; glumes 1-nerved, 

 1 and 1^/2 lines long; lemmas 1% lines long, smooth. 



Alkaline soil, in the northern Sierra Nevada (Sierra Valley, Bolander}.
