Carpinus japonica
Carpinus japonica, the Japanese hornbeam, is a hornbeam endemic to Japan but cultivated elsewhere as an ornamental. It is a deciduous tree growing to tall with leaves that are longer and darker than the European hornbeam ("Carpinus betulus"). The leaves are dark, glossy and slender, with 20-24 pairs of parallel sunken veins; every third tooth is whisker-tipped. The prominent catkins are green turning to brown. This tree has gained the Royal Horticultural Society's Award of Garden Merit.
