160 NORTH AMERICAN FAUNA. [wo. 16. 
handsome scarlet flowers are very attractive. On warm southwest 
slopes near Panther Creek it was found as high as 6,600 feet, and 
between Mud and Clear creeks as high as 6,700 feet, bit these are 
abnormal altitudes due to unusually warm exposures and soil. 
Collomia grandiflora Dougl. 
Common in the upper part of the Transition zone a little below Wagon 
Camp, where it was flowering abundantly the last half of July. 
Phlox douglasi diffusa (Benth.) Gray. Alpine Phlox. 
A common, widely distributed, aud conspicuous plant of the higher 
slopes within the Hudsonian zone, sometimes straggling down into the 
Canadian zone. It occurs in scattered tufts on the dry rocky slopes 
and ridges, usually on pumice soil, and is commonest in the neighbor- 
hood of timberline. It blossoms early, and flowers were rarely seen 
as late as the latter part of July. After flowering the whole plant 
withers and is disintegrated by the wind, so that little more than the 
woody base remains. 
Polemonium pulchellum Bunge. 
A. characteristic but not abundant Alpine species, occurring here 
and there among rocks far above timberline. On the north side of 
Shastina it was in full bloom July 24 at an altitude of 8,900 feet. On 
the south side of Shasta, above Squaw Creek, and on both sides of 
Mud Creek Canyon, it was not found below 9,500 feet, whence it ranges 
up to 13,000 feet. This species and Draba breweri were both observed 
at 13,000 feet, and are the highest plants found on Shasta. (Identified 
by Professor Greene.) 
Phacelia frigida Greene.! Dwarf Alpine Phacelia. 
This new species, which Professor Greene has kindly described at 
my request from specimens collected by us above the head of Squaw 
Creek, is common and widely distributed on the higher and more bar- 
ren rocky slopes, beginning above timberline and reaching, on south- 
erly slopes, as high at least as 10,200 feet. The lowest altitude at 
which it was found is 8,700 feet, on a cold slope. 
Phacelia magellanica (Lam.) Coville. 
A plant which, in the present unsatisfactory state of the group, it 
seems necessary to refer here, is abundant on the lower slopes, par- 
ticularly in the Transition zone, where it was in flower throughout the 
summer and as late as the end of September. 
Cryptanthe geminata (:reene. 
Rather common in the Transition zone below Wagon Camp. (Identi- 
fied by Professor Greene.)
