204 BOTANY. 
long- acuminate, with a few very narrow almost filiform elongated teeth near 
the middle.— Middle Park, Colorado, (Parry, 1864.) Canons of the East 
Humboldt Mountains and on a peak west of Parley's Park in the Wah- 
satch ; 7-9,000 feet elevation ; July-September. (716.) 
Crepis acuminata, Nutt. Torrey, in Stansb. Bep. 392, t. 8. Perennial; 
stem sparingly canescent, 1-3° high ; leaves pubescent, the radical ones 
lanceolate, long-acuminate, 6-9' long, tapering into a petiole often two-thirds 
as long, laciniately pinnatifid into numerous linear-lanceolate spreading or 
curved usually entire teeth ; cauUne leaves few, mostly sessile, the lower 
similar to the radical, the upper linear, entire ; heads 5-7-flowered, very 
numerous in a compound fastigiate corymb ; involucres glabrous or nearly 
so, cylindrical, calyculate with a few ovate appressed bractlets ; the proper 
scales 6-7, about 5" long; mature achenia tapering shghtly upward, 10-stri- 
ate. — The figure in Stansbury's Eeport shows a plant with the foliage more 
like that of C. occidentalism and achenia more decidedly beaked than either 
species affords among the numerous specimens now examined, though it cor- 
rectly represents the very numerous slender heads of C. acuminata. Ore- 
gon and California to Colorado and Nebraska ; Mt. Davidson, (Bloomer !) 
Stansbury Island, (Stansbury.) Hill-sides from Western Nevada to the 
Uintas ; 5-7,000 feet elevation ; May-July. (717.) 
Teoximon cuspidatum, Pursh. Northern Illinois and AVisconsin to Ore- 
gon, (Spaulding!) Valley of Grreat Salt Lake, (Stansbury.) 
Macrorrhynchus ^ GLAUCUS. ( Troximon glaucum, Nutt.) Perennial, 
smooth and somewhat glaucous ; leaves linear-lanceolate or lanceolate, 3-6' 
long, about 6" broad, entire or slightly runcinate-toothed ; scapes 6—9' high ; 
involucral scales unequal, the outer ones shorter and broadly ovate-lanceolate, 
slightly pubescent; inner ones lanceolate, 7-9'' long; achenia 10-ribbed, 
contracted toward the summit, but scarcely beaked ; pappus rather coarse, 
longer than the aclienium. — Saskatchewan to Nebraska and Colorado, (65 
Parry, 354 Hall & Harbour, in part, 260 Vasey %) Var. laciniatus. ''Leaves 
1 .MACRORRHYNCHUS, Li:ssix< ;. Heads many-flowered, the flowers all ligulate. Involucre cam- 
pauulute; the lanceolate or ovate-lauccolato scales imbricated in 2-3-8eries, the inner ones scarious-mar- 
gined, the outer ones sometimes shorter, often foliaceoiis. Receptacle naked, or very rarely with a few 
chaffy scales among the flowers. Achenia glabrous, terete or slightly obcompressed, 10-ribbcd or 
winged, narrowed above and in most species at length produced into a long slender beak, the apex di- 
lated into a small flat disk. Pappus of copious white scarcely scabrous soft and capillary or coarser 
and somewhat rigid bristles. — Annual or perennial herbs of Western America, North and South, nearly 
or quite acaulescent, with rather large heads solitary on long naked scapes, and entire or laciniate-pin- 
natilid often elongated leaves ; flowers yellow, rose-color, or purplish.
