occur at various altitudes up to timber line in the Micawber Mine 
Gulch: Artemisia scopulorum, A. franserioides, Antennaria 
_ Giotca, var. rosea, D. C. Eaton, (remarkable nodding forms at 
timber line), Zyroximon aurantiacum, T. glaucum, {. alpestre, 
(beak of akenes about 6 millemeters long, hardly as long as the 
pappus, the bracts with dark blotches outside, the leaves narrow, 
and entire). Cnécus Parryt, Aplopappus Parryi, Erigeron glabellus, 
var. mollis, and Arnica cordifolia. Helianthus petiolaris, near the 
Micawber, sprung from a dropped seed, and looked strangely 
out of place. 
CAMPANULACEX. Campanula rotundifolia, Horseshoe Bend 
Gulch and Micawber Mine Gulch. 
ERICACE&. Moneses uniflora and Pyrola secunda, near the 
lakes; and Arctostaphylos Uva-ursi, Vaccinium myrtillus and 
_ Pyrola rotundifolia var. uliginosa, near the Micawber. The Vac- 
cinium replaces Arctostaphylos as we ascend. 
PRIMULACE&. Dodecatheon media in the Micawber Mine 
Gulch, and var. alpinum, near the lakes. Primula Parryi is 
conspicuous in Swift Creek Gulch, and Horseshoe Bend Gulch.* 
APOCYNACEA. Afpocynum androsemifolium near the Mi- 
cawber. 
GENTIANCEH. Jyrasera speciosa is abundant at timber line, 
near Brush Creek,and lower down one meets with Gentiana 
heterosepala, and near the Micawber G. barbellata, the latter being 
also found near the lakes. I found Swertia perennis in flower at 
the lakes in September, and Mrs. E. B. Cox showed me a speci- 
men of Gentiana frigida also collected there. : 
POLEMONIACE. Polemonium humile var. pulchellum and 
P.-confertum,+ near the lakes, the latter at timber line, above 
Brush Creek, where also occurs Phlox cespitosa—a form with 
the corolla-tube much exceeding the calyx. 
* P. angustifolia occurs near the top of the range, not far from the lakes, but 
on the Saguache County side. 
+ It may here be worth while to record that Mr. W. C. Roby sent me a 
specimen of what is apparently without doubt P. viscosum, Nutt., collected at 
12,000 feet on Holy Cross Mountain, This adds a new locality for this rare species.
