154 NORTH AMERICAN FAUNA. (atin 16. 
Tongues of it push up on warm southerly slopes to about 6,600 feet' 
altitude, and it descends on the west slope to about 4,200 feet (half a 
mile east of Sisson), and on the south slope to 3,600 feet (near McCloud 
Mill). Along the east base of Mount Eddy, where it is sheltered from 
the afternoon sun, it appears about 2 miles north of Sisson (altitude 
3,700 feet), and continues northerly for many miles. 
Ceanothus integerrimus H. & A. California Lilac. 
Common in parts of the Transition zone, notably in Squaw Creek 
Valley near McCloud Mill, and in the upper Sacramento Valley a little 
below Sisson, but very scarce or absent on the slopes of Shasta proper. 
Like C. cordulatus it seems to be kept out by some unknown cause, 
possibly choked out by other species. Perhaps the soil is too dry for it. 
Ceanothus (Cerastes) prostratus Benth. Squaw Carpet. 
In following the Sacramento Canyon northward, Syuaw Carpet was 
first seen at the ‘The Loop,’ a few miles south of Sisson, whence it 
occurs in greater or less abundance throughout the ponderosa pine 
forest and manzanita chaparral to the lower slopes of Shasta, where on 
the southwest side it reaches up to 5,200 feet. 
Rhamnus californica Esch. (This form may be &. rubra Greene.) 
Searce and contined to low altitudes in the Transition zone. Found 
by Vernon Bailey in Squaw Creek Valley below 4,000 feet. Specimen 
lost. 
Hypericum anagalloides C. & S. Dwarf Hypericum. 
Common in spots in wet places in the Hudsonian and Canadian zones. 
It was most common in the second meadow on Squaw Creek, aud by 
no means rare near Wagon (Camp, and was in flower in late July and 
throughout August. 
Viola blanda Willd. White Violet. 
Collected by Miss Wilkins in the middle meadow on Squaw Creek, 
at an altitude of 7,500 feet. Not observed elsewhere. 
Viola purpurea Kellogg. Alpine Yellow Violet. 
Common on dry rocky slopes on pumice soil from some distance 
below timberline upward, on warm southerly exposures, to 9,300 feet. 
When we reached the mountain, the middle of July, its yellow flowers 
were conspicuous, although even at that time the species had nearly 
passed flowering. Its fruit and dark green leaves remained as late as 
the latter part of September, sharply outlined against the whitish 
stones and pumice of the bleak and barren upper slopes, where a violet 
seemed singularly out of place. (Identified by Miss Eastwood and 
Professor Greene.)
