Leaves of a Japanese Maple
This variety of Japanese maple is prized for the color of the leaves, and very justly so. There are other varieties, however, in which the leaves are curiously reticulate, some of them giving the appearance of leaves that have been dissected so that only the ribs remain. It would be of great interest to cross maples of these two types, noting the results in the first and second generations.
