EXOGENOUS OR DICOTYLEDONOUS PLANTS. 441 and with scales instead of leaves. — Ex. Monotropa, the Indian-Pipe and Pinesap. 857. In this diversified and widely diffused order, the bark andfoliage are generally astringent, often stimulant or aromatic from avolatile oil or a resinous matter, and not seldom narcotic. Thus, theleaves of Rhododendron, Ivalmia, and all the related plants, aredeleterious (being stimulant narcotics), or suspicious. The honeymade from their flowers is sometimes poisonous. The Uva-Ursiand the Chimaphila (Pipsissewa) are the chief medicinal plants of. the order. The berries are generally edible, and some are largelyused for the dessert; as Cranberries, Blueberries, and Huckleber-ries. The fleshy calyx of Gaultheria (Checkerberry, or Winter-green) has a very pleasant and well-known aroma. Many Ericaceaeare cultivated for ornament, especially Rhododendrons and Azaleas,Heaths and Epacrises. FIG. 922. Pyrola chlorantha, reduced in size. 923. Enlarged flower. 924. Magnified sta-men. 925.
