ing variety, showing the tendency to vary to red—red being a 
normal color in others of the genus. 
ONAGRACEH. E£pilobium spicatum is of course abundant. 
At the Micawber is found £. coloratum f. albiflorum, with white 
flowers and glabrous pods. The (Cotheras, so conspicuous 
lower down, are completely absent. 
UMBELLIFER&. Near the Micawber are Heracleum lana- 
tum, Ligusticum montanum and Osmorhiza nuda. On bare 
ground at timber line I found a Peucedanum, apparently dzcolor. 
I submitted it to Dr. Coulter, who remarked that so far as vege- 
tative characters went it agreed with Jdzco/or, but since it was 
gathered too early for fruit, its identity could not be made certain. 
CAPRIFOLIACE®.  Lonicera involucrata, Symphoricarpos 
oreophilus, and Sambucus racemosa, near the Micawber, and the 
last also in Swift Creek Gulch. The variation in the color of the 
fruit of S. racemosa, near the Micawber, is very striking. The 
ordinary form has bright scarlet fruit, but there are two varieties; 
f. xanthocarpa, with cyme rather broader, peduncles deep 
dark crimson, fruit pale yellow, leaves larger ; and f. o¢nocarpa, with 
fruit dull crimson. These varieties all grow together, and appear 
to differ in only the characters given here. According to 
Wood, Sambucus “ pubens” has “berries rarely white.” Al- 
though these elder-berries are so conspicuous, they do not seem 
to be eaten, not at any rate very largely, by birds. 
RUBIACE&. Galium boreale is abundant near the Micawber 
Mine. 
COMPOSITZH. Senecio aureus var. croceus, S. -Fendleri, S. 
werneriefolius, Aster foliaceus var. Parryi, Cnicus eriocephalus, 
Troximon glaucum, Aster Fremonti, and Achillea millefolium 
occur near the lakes, and the last two near the Micawber Mine. 
Cnicus ertocephalus, a form with bright, chrome yellow corollas, 
is very conspicuous above the timber line, near Brush Creek. 
Aster Fermonii, near the Micawber, has two forms, a. pallidus, 
rays white, or nearly so, 4. vividus, rays shorter, more numer- 
ous, lilac, with the outer involucral bracts dark, and shorter, radical 
leaves about 109 millemeters long. Gymnolomia multiflora occurs
