OSTRYA CARPINIFOLIA (syn O. vulgaris).—Common Hop Hornbeam. South Europe, 1724. A much-branched, round-headed tree, with cordate-ovate, acuminate leaves. Both this and the following species, by reason of the resemblance between their female catkins and those of the Hop, and between their leaves and those of the Hornbeam, have acquired the very descriptive name of Hop Hornbeam. This is a large-growing tree, specimens in various parts of the country ranging in height from 50 feet to 60 feet.
O. VIRGINICA.—Virginian Hop Hornbeam. Eastern United States, 1692. Resembles the latter, but is of smaller growth, rarely exceeding 40 feet in height. They grow fairly well in almost any class of soil, and on account of the long and showy catkins are well worthy of cultivation.
