A small tree, rarely 7 to 9 meters in height, with a trunk 0.30 to 0.37 meter in diameter (Pringle), or commonly 

 a shrub, along the sea-coast and at high elevations often prostrate; common and reaching its greatest development 

 in the valleys of the Santa Cruz mountains. A low shrubby form, densely white-tomentose, especially on the 

 under side of the leaves, of southern California, Arizona, and New Mexico, is

BEARBERUY. BEAR WOOD. SHITTIM WOOD. 



Puget sound, east along the mountain ranges of northern Washington territory to the Bitter Root mountain, 

 Idaho (Mullau pass, Watson), and the shores of Flathead lake, Montana (Canby & Sargent), southward through 

 western Washington territory, Oregon, and California, west of the Sierra Nevada, to about latitude 40. 



A small tree, often 12 meters in height, with a trunk 0.30 to 0.45 meter in diameter ; depressions and along 

 the sides and bottoms of caiious in the coniferous forests, reaching its greatest development along the western slope 

 of the Coast Eange of southern Oregon. 



Wood light, very hard, not strong, close-grained, compact, satiny; medullary rays numerous, thin; color, light 

 brown tinged with yellow, the sap-wood somewhat lighter; specific gravity, 0.5072; ash, 0.67. 



The bark, like that of other species of the genus, possesses powerful cathartic properties, and, under the name 

 of Cascara sagrada, lias recently been introduced by herbalists in the form of fluid extracts, tinctures, etc., 

 immense quantities being gathered for this purpose in the Oregon forests (Nat. Dispensatory, 2 ed. 659).

BLUE MYRTLE. 



California Coast ranges, from Mendiciuo county south to the valley of the San Louis Eey river (Pala, Parish 

 Brothers). 



A small tree, 8 to 10 meters in height, with a trunk 0.10 to 0.15 meter in diameter, or toward the southern 

 limits reduced to a low shrub ; common and reaching its greatest development in the Sequoia forests near Santa 

 Cruz. 



Wood light, soft, close-grained, compact; medullary rays very obscure; color, light brown, the sap-wood 

 darker; specific gravity, 0.5750; ash, 0.69. 



The bark of the root may be expected to possess similar astringent properties to that of the shrubby C. 

 Americana, used with advantage in cases of diarrhea and dysentery, and as a domestic remedy in throat troubles 

 ( U. 8. Dispensatory, 14 ed. 1609. Nat. Dispensatory, 2 ed. 373).
