pappus of five strong awns and about ten very short intermediate teeth ; 
inner pappus of about fifteen capillary bristles, deciduous in a ring. — In this 
and other allied species of Malacothrix the stronger bristles of the pappus 
certainly belong to the cup-like crown, and not to the deciduous pappus, as 
was supposed by Drs. Torrey and Gray. (See Stansh. Rep, 392 ; PL Fendl. 
113; PI. Wright. 2. 105.) From Nebraska (Nuttall) to the shores and 
islands of Great Salt Lake (Stansbury) and Oregon, (Geyer ;) Carson City, 
(67 Anderson.) Foot-hills and gravelly slopes throughout Nevada ; 4,000- 
6,000 feet elevation ; May-July. (710.) 
Malacothrix obtusa, Benth. Plant. Hartiv. 321. Annual, erect, 
])ranchiug, 2-12' high; leaves at first whitish-woolly above, soon nearly or 
quite glabrous ; the radical ones 2-3' long, runcinate-pinnatifid with obtuse 
dentate lobes ; stem-leaves linear, toothed or entire ; heads small, 5-7" wide ; 
involucre bell-shaped, calyculate, the inner scales subequal, oblong-linear, 
white-margiiied, 3" long ; flowers yellow or whitish ; achenia 5-costate and 
with intermediate pairs of smaller ridges ; outer pappus cup-like, obtusely 
about 24-toothed, without aw^ns ; inner pappus rather coarse, very scabrous, 
deciduous.— Near the last, but with much smaller heads, and no persistent 
bristles of the outer pappus. California, (Hartweg, Parry, Brewer!) 
Stansbury Island, Great Salt Lake ; 4,300 feet elevation ; June. (711.) 
Crepis ' RUNCiNATA, T. & G. Perennial, hirsute or becoming nearly 
smooth ; radical leaves oblong or obovate, runcinate-lobed or only shghtly 
toothed ; scape 1-2° high, branching, bearing a few linear bract-hke leaves; 
branches and involucres more or less hirsute with blackish often glandular 
hairs ; involucres many-flowered, calyculate, the scales linear-lanceolate, with 
scarious margins ; achenia slightly tapering upward, striate.— Saskatchewan 
to Nebraska and Colorado ; Oregon, (Geyer.) Meadows and wet places near 
Salt Lake City, and in the Wahsatch and Uintas ; 4,300-7,000 feet eleva- 
tion ; :\[ay-July. The present specimens are much larger than those from 
Colorado, and are much more blackish-liirsute on the peduncles and involu- 
cres. (712.)
