BOTAXT. 
(11 Geyer.) In the East and West Humboldt Mountains, Nevada, and in 
the Wahsatch ; 7-10,000 feet altitude ; July-September. (1,303.) 
What seems to be merely a reduced form was also collected, 1° high 
and very slender, with the leaves narrow and revolute, the panicle very nar- 
row and with but 10-15 spikelets. This is nearly G21 Hall & Harbour, from 
Colorado, which, however, has the glumes more acute and the culms less de- 
cidedly enlarged at base, and was collected also by Bourgeau at the east base 
of the Rocky Mountains. (1,304.) 
Melica stricta, Bolander. Proc. Calif. Acad. 3. 4. Culms 6-18' high, 
slender, erect, purple at base, slightly scabrous above ; nodes smooth, covered ; 
sheaths and leaves pubescent ; hgules broad, entire or lacerate ; panicle inter- 
rupted, secund, the branchlets in pairs or solitary, pubescent and strongly 
curved above, bearing a single nodding spikelet ; glumes 2-4-flowered, pur- 
plish, nearly equal, thin and membranous, glabrous, obtuse, Q" long ; lower 
palet rather more rigid, sKghtly puberulent on the back, 7-nerved, obtuse or 
acutish, 5" long ; upper palet nearly half shorter, pubescent on the nerves. — 
Yosemitc Valley. Not rare on the mountain ranges of Nevada; 5-10,000 
feet altitude ; May-September. (1,305.) 
Glyceria pauciflora, Presl. Steud. Grain. 285. Roots creeping; 
culms 1-3J° high, smooth, nodes naked ; sheaths and the broad-hnear leaves 
(3-12' long) scabrous; panicle loosely spreading, the slender flexuous 
branches in pairs, divided, scabrous ; spikelets narrow-oblong, 2" long, 4-6- 
Howered, often purpHsh; glumes rounded, unequal, the lower obscurely 
3-nerved, scarious on the margin, lower palet truncate-obtuse, the apex mi- 
nutely serrulate and distinctly scarious, 5-nerved, the upper one emarginate. — 
Described by Presl as near G. Jluitans, but it much more closely resembles 
G. aqiiatica. Frequent in Oregon and Washington Territory and extending 
eastward to Colorado, (662 Hall & Harbour ;) specimens from Mendocino 
County, California, have the rounded apex of the lower palet frequently ab- 
ruptly acute. Bear River Canon in the Uintas ; 8,000 feet aUitude ; Au- 
gust. (1,306.) 
Glyceria aquatica. Smith. From New York to Wisconsin, Lake 
Winnipeg and tlic Saskatchewan region, and in the Rocky Mountains south- 
ward to Colorado; Oregon ; California. Ruby and Huntington Valleys and 
in the Clover Mountains, Nevada, and in Salt Lake Valley, Utah ; 4 500- 
6,500 feet altitude ; June-September. (1,307.)
