and leaves scabrous; leaves mostly radical and narrower, 1-2" wide,3-6' 

 long, the cauline few and very short or nearly obsolete ; ligule short : panicle 

 loose and spreading, the short (1' long or less) branches in pairs or solitary ; 

 spikelets 3-5" long and 1 J" broad, 4-6-flowered, purplish ; glumes acutish ; 

 palets very villous on the back and margins, obtuse and carinate, but less 

 flattened and less strongly nerved than in the last. — Found by Prof. Daniel 

 C. Eaton in a rocky gulch of Cottonwood Canon in the Wahsatch ; 6,000 

 feet altitude ; June. Very similar specimens have also been collected by Dr. 

 Bloomer near Virginia City, Nevada. 



PoA (?) KiNGii. Culms rather stout and strict, 12-20' high, and with 

 the sheaths glabrous ; leaves 2-10' long, 2" wide or more, subscabrous ; 

 ligules short or nearly obsolete ; panicle nearly glabrous, 2-4' long, erect and 

 strict, more or less interrupted, the branches often solitary, short, bearing 

 1-3 spikelets; glumes 2-4" long, membranous, acute, smooth, 3-5-flowered; 

 lower palet puberulent, not villous nor webby, 3" long, acute, the upper one 

 roughly short-ciliate on the keels ; scales large and distinct, nearly equaling 

 the ovary, ciliate ; the strongly plumose stigmas mostly long and conspicuously 

 exserted ; ovary 1" long, bearded above. — A very strongly marked species, 

 but not wholly agreeing with the characters of the genus. Frequent on the 

 East Humboldt Mountains, Nevada; 7,500-10,000 feet altitude ; July-Sep- 

 tember. (1,317.) 



PoA TENuiFOLiA, Nutt., Ms. in Herb. Tufted, 1-2° high ; culms slender, 

 erect ; glabrous, or with the sheaths and leaves more or less scabrous ; leaves 

 narrowly linear, 1-6' long ; ligules short ; panicle erect, narrow and rather 

 close, 2-6' long, the branchlets 2-5 together and scabrous ; glumes 2-2 J" 

 long, acute or acutish, a little scabrous on the midvein, 3-4-flowered ; lower 

 palet 2" long, obtuse, nearly glabrous, puberulent or somewhat pubescent at 

 base, but little compressed ; flowers readily separating at the joints. — Like 

 the following an ambiguous species, intermediate between Glyceria and Poa, 

 but apparently more nearly allied to the latter genus, in which they are here 

 provisionally retained mider old Nuttalhan names. It is the same as 668 

 and 675 Hall & Harbour, (distributed as Atropis Calif ornica, Munro,) and is 

 apparently common from Colorado to Oregon and Washington Territory. 

 It is one of the most abundant as well as the most valuable of the " bunch" 

 grasses of Nevada. The grain, though small, is extensively gathered by the 

 natives for food. Occurring on the foot-hiUs and mountains, less frequently
