The Magnolia family, comprising about 10 genera and 85 species of trees and shrubs, is represented in North America by 4 genera, two of which contain only shrubs. The other two include the valuable Magnolias and Tulip Tree which not only produce large quantities of choice lumber but are among the most desirable of our ornamental trees.

Magnolia, (pp. 125, 127, 129).—Most of the 25 species of Magnolias are tropical only one venturing as far north as southern Canada. Three species are native in West Virginia. Magnolia virginiana, a fragrant-flowered species growing farther east and south, is sometimes planted in West Virginia but is not hardy. Several shrubby and arborescent Chinese and Japanese species are also grown for ornamental use.

Liriodendron, (page 131).—The Chinese Liriodendron chinensis and our common Tulip Tree are the only known species belonging to this genus.
