LXX. CORYLA‘CEA: O'STRYA. 921 
Florida. Height 15 ft. to 40 ft. Introduced in 1692. Flowers and fruit 
as in the preceding species. 
The Virginian hop hornbeam, or iron wood, 
generally forms a tree about 30 ft. high, growing 
more rapidly than O. vulgaris, and differing from that 
species, according to Willdenow and Pursh, chiefly 
in the position of its fe- 
male catkins, which are 
upright, instead of being 
pendulous. The tree, ac- 
cording to Michaux, is 
easily known, in winter, 
by its smooth greyish bark, 
which is finely divided, and 
detached in strips of not 
more than aline in breadth. 
In British gardens the tree 
bears a close resemblance 
to the European hop horn- x)
