snow banks, and the buds can often be seen under the thin crust of 
melting snow. The flowers vary from an inch or more in diameter 
to a half inch orless. Inthe San Juan Mountains, above Silverton, 
it is abundant along the edge of snow banks. The leaves are 
three-toothed at the truncate apex and entire below; the calyx 
is thickly covered with soft brown wool. Specimens from the 
Elk Mountains, above Irwin, have the petals usually entire, but 
occasionally flabelliform, leaves almost orbicular and crenate 
nearly to the base, the silky wool dense on the calyx. The form 
from the La Plata Mountains has the calyx either densely or 
sparingly hirsute; the root leaves oblong-lanceolate; stem leaves 
not cleft as in the other two forms. 
RANUNCULUS GLABERRIMUS Hook. Specimens of this from 
Mancos have cauline leaves entire as well as deeply 2—-3-lobed, 
akenes plainly hispid. I have found no plants with three large 
blunt teeth at the apex of the leaves. 
DELPHINIUM OCCIDENTALE Watson. This varies greatly. At 
Steamboat Springs, in Routt County, it is one of the commonest © 
plants; but rarely could two plants be found with flowers colored 
alike. ‘They ranged from dark blue to white, and the forms 
between, where the two shades mingled, were mottled and 
striped, one part colored blue in one flower, white in another, so 
infinitely varied that to collect all forms was impossible. Usually 
it is found at subalpine elevations and is dark blue. I have 
specimens from above Irwin, in the Elk Mountains, in which all 
parts of the flower have become blue, bract-like petals. 
AOQUILEGIA ECALCARATA Eastwood. ‘This has been collected 
in Southwestern Colorado in but one limited locality, about 
twenty-five miles from Mancos, near the head of Johnston Cafion 
that forms a branch of the Mancos Cafion. It was abundant 
under an overarching rock that even late in August was still 
wet with the alkali water that oozed from it. The plants were 
growing in the sandy soil, loosely branching and also climbing up 
the rocky wall, apparently seeking moisture. The few flowers 
still in bloom were on stems that clung to the rock, but the plants 
were full of dry seed pods that indicated their earlier abundance. 
The pubescence is glandular and the flowers pink or white.
