. Botany for high schools and colleges. Botany. EBICALES. 509 Figs. 436-9.—Illustrations of Erica cinerea.

Suh-Orcler Ericinece,—About 1000 species of shrubs, many evergreen. Many are of great beauty, and are extensively grown as ornaments ; others are good-sized trees, and furnish valuable tim- ber. (Figs. 486-9.) Arbutus Menziesii, the Madrona of the Pa- cific coast of the Unit- ed States, is an ever- green tree twenty-four to thirty metres (80 to 100 ft.) in height. Its hard wood is useful in furniture-making. Arctostaphylos pun- gens and A. glauca are large evergreen shrubs of California, which bear the name of Man- zanita. The heavy, dark-colored, and fine- grained wood is used in turnery and furniture- making. The berries are eaten by grizzly bears. A. Uva-ursi, the Bearberry of the colder portions of North America, Europe, and Asia, bears bitter and astringent leaves, which are oflBcinal. Calluna vulgaris, the Common Heath of Central and Northern Europe, is a low, straggling evergreen under-shrub. Its stems are made into brooms, and its flowers aflbrd an abundance of excellent honey. It occurs in a few scattered localities in Massachusetts, Maine, Nova Scotia, and northward, but it is doubtful whether it is really indigenous to any part of the United Fig. 438. Fig. 439.
