we have also referred to this species, though there are some slight dif- 
ferences. 
The wrinkled fruit-wings are very striking in the immature stage that 
has been collected, but many fruit- wings show the same* sort of wrinkling 
while immature and become plane enough when fully developed. The 
characters of leaves and inflorescence, however, serve well to distinguish 
this species from (7 globosus. 
5. C. nivalis Watson, King’s Rep. v. 123. With long and 
branching caudex, glaucous, minutel}^ scabrous-puberulent to gla- 
brous: leaves simply pinnate, wdth leaflets 3 to 5-lobed or pinnately 
dissected, the segments oblong-lanceolate: peduncle 2 to 4 inches 
high, exceeding the leaves, bearing a small nearly capitate umbel; 
involucels of broad obtuse membranous bractlets united at base 
and nearly equalling the white or pinkish flowers: fruit- wings 
equal, thin: section unknown. 
East Humboldt Mountains, Nevada, 9000 to 10000 feet altitude, July 
and August (Watson).

t Involucre and Involucels both conspicuous. 
6. C. montanus Ton*. & Gray, FI. i. 624. Leaves clustered 
at the summit of the very short stem, glaucous and glabrous (rarely 
slightly puberulent) : leaves pinnate or bipinnate; pinnm oblong, 
pinnatifld with oblong obtuse entire or toothed lobes: peduncles 1 
to 6 inches high: rays 3 to 9 lines long; pedicels very short; invol- 
ucre and involucels of mostly broad membranaceous usually green- 
veined bracts, more or less united: fruit oblong in outline, 3 to 6 
lines long, the 3 to 5 carpel wings broad and thin (thick at base): 
oil-tubes 1 to 3 in the intervals, 4 to 8 on the commissural side, 
(Fig. 79.) 
From New Mexico to Colorado, Utah, and Yellowstone Park (Tweedy), 
east to Texas, Kansas (L. Watson), and Nebraska {Hayden). FI. March 
and April. 
This is Fendler 275 and Hall <& Harbour 211. The speciesl is quite 
variable in its involucre and involucels. While in some specimens they 
are quite conspicuous and almost cup-like, in others they are narrow and 
nearly distinct. 
Var. purpurascens Gray, Ives Colorado Rep. 15. With 
very broad and conspicuous involucels nearly enclosing the flowers, 
obtuse and tinged or veined with purple and green: fruit large and 
very broadly winged. — C. montanus globosus Watson, King’s 
Rep. V. 124, as to rruit. 
From New Mexico to S. California {Parish) and Nevada.
