The best-known kind is canadensis, a lovely North American tree, with oblong elliptic pointed leaves which assume deep-red and brown tints in autumn. It bears masses of snowy-white Hawthornlike flowers in April. The fruits are purple crimson. There are several varieties, such as florida or alnifolia (fig. 410), ovalis, rotundifolia, san-gwinea, etc. The ordinary form is raised from seeds, but the varieties are grafted on the Hawthorn. A. vulgaris is a European shrub, with roundish oval leaves, white flowers, and deep-purple fruits.
