The handsome Hornbeam now figured is interesting as 
belonging to a well marked section of the genus Carpinus 
which some authors have separated under the name 
Distegocarpus. The distinctive characters that separate 
Disteyocarpus from Eu-carpinus, which includes all the true 
Hornbeams, are the more numerous parallel nerves, the 
closely imbricated fruiting bracts and the existence of a lobe’ 
or intolded base to each bract which completely covers the 
nutlet. The only other species in the section Distegocarpus 
is C. cordata, Blume, which is well distinguished by its 
larger and broader leaves with fifteen to twenty pairs of veins, 
and by the basal lobe of the bract being twice as large as 
in C. japonica, and being attached by its side as well as by 
its base. C. japonica appears to have first been introduced
