was found in flower at 10,000 feet, as late as Oct. oth. Achillea 
millefolium, on Oct. toth, was the last flower of the year at that 
high altitude. 
CAPPARIDACE#. This order has only a place in this list be- 
cause seeds brought in hay to the Micawber Mine gave rise to a 
plant or two of Cleome integrifolia, a species normally occurring 
from 8,000 feet downwards. 
VIOLACE&. Viola Canadensis, in the Micawber Mine Gulch. 
CaARYOPHYLLACE&. <Avenaria saxosa near the lakes; and 
Silene acaulis, at timber line, above Brush Creek, the latter a form 
with pink flowers on peduncles about 15 millimeters long. 
Saponaria Vaccaria, growing near the Micawber, is merely the 
result of seeds from hay. 
MaLvACE#&. Szdalcea candida, near the Micawber. 
SAPINDACE&. Acer glabrum, common near the Micawber. 
LEGUMINOS&. Trifolium Parryiand T. dasyphyllum, near 
the lakes—the latter also near Brush Creek. In the neighbor- 
hood of the Micawber we find Thermopsis montana and Astragalus 
alpinus, (a form with stipe shorter than calyx); and in Horse- 
shoe Bend Gulch, at barely 10,000 feet, Lupinus argenteus occurs 
on a sunny slope. 
RosacE#. Near the lakes, Potentilla dissecta, P. fruticosa, 
Rubus strigosus, and Fragaria vesca—and the last three also near 
Brush Creek. Above the Micawber Mine occursa f. Aumi/is of P. 
Jruticosa, a lower form with about twenty-five stamens: the more 
ordinary form has about thirty stamens; so this species varies in 
this matter like the avguta section. In the Micawber Mine Gulch 
are also found Potentilla gracilis, Rosa blanda, and Geum ma- 
crophyllum. 
SAXIFRAGACE&. Saxifraga nivalis, S. bronchialts, S. 
punctata, and Ribes lacustre near the lakes, and the last three also 
near Brush Creek. Parnassia fimbriata occurs near the Micaw- 
ber. | 
CRASSULACEH. Sedum rhodanthum, near the lakes; and 
above the Micawber S. stenopetalum, with a f. rubrolineatum, in 
which the angles of the closed buds are red; when the flower is 
open the peculiarity is less conspicuous. This is a very interest-
