Ostrya — Hop Hornbeam, Ironwood. 209 



E. alatus, or Japanese winged euonymus, proves to be 

 large and well-shaped, with many of the best characteris- 

 tics of the family, and in every way a most desirable 

 garden plant. Its early buds in spring are marked with 

 pink, which gives it a peculiar appearance. The foliage is 

 agreeable at all times, in autumn turning to a pink or dark 

 red hue. The flowers are white and not at all showy, but 

 masses of brilliant scarlet berries afford an autumnal ex- 

 hibit of rare beauty. It is not much planted as yet, but 

 as it is quite hardy and easily grown it has only to be 

 better known in order to win popular favor. 



OSTRYA — Hop Hornbeam, Ironwood. 



THIS is a genus of the order Corylacecs, of but 

 three known species. Until recently, there has 

 been supposed to be but one in Europe, and 

 one in America, but within a few years a second American 

 form has been discovered in Colorado, though it is smaller 

 and in almost every way inferior to those which have 

 been longer and so much better known, and but little 

 account in this connection need be made of its presence. 

 It has been named O. knowltonii in honor of the discov- 

 erer, Mr. Frank H. Knowlton, and is interesting chiefly 

 as a curiosity. The European species, C. vulgaris, has 

 long been recognized in the Old World, and considerably 

 planted, but now has practically given way to the Ameri- 

 can species, which answers a much better purpose. 



O. virginica, or hop hornbeam, is a small tree, in the 

 extreme North scarcely more than a shrub, of slender form, 

 with foliage somewhat resembling that of the black birch.
