    ⑪ The back side of the leaves is pale green with early hair, but after that it becomes hairless, but the hair remains in the base vein axil.
    ⑫ The young branches are green, but the surface may be reddish and hairless. ⑦ The back side is green, hair is present at the base of thepalmar vein and the axilla ⑦ The back side is light green,with light yellowish brown hair remaining at the base of thepalmar vein .
    The surface of the petiole has a reddish color.
    ⑧ Young branches are green to purplish purple and hairless.
    Points of how to distinguish
    Iroha Homiji, Yamamomiji and Oomomiji are similar in that the leaf margin is divided into 5 to 9 leaf margins in the genus Aceraceae and the shape of the leaves is almost circular, but in the following points It can be distinguished.
    (1) The size of the leaves is the smallestIrohomomorida is less than 6 cm in length , and the leaves of Yamamomiji and Oomomiji are about the same size and more than 6 cm in length.
    (2) Oomomiji leaves are large, fragments are mixed
    finely prepared single teeth and heavy teeth, whereas Irohomomiji and Yamamomiji have heavy teeth. (3) Both of Iroha Homiji and Yamamomiji have both irregular heavy teeth, while Yamamomiji has a larger leaf size than Iohamomiji, there are many cases where there are grooves in the upper part of the petiole, whereas the leafhopper is small There is no groove in the petiole .
    (4) Yamamomiji is mainly distributed on the Japan Sea side.
    Note: Many garden cultivars are made from these three species, and accurate distinction is difficult.

    Done. I called it How to distinguish similar species, as what shows on the browser tab is "Search tree for trees with leaves and branches How to distinguish similar species Others:" (followed by four names that I don't think are names we use).
    So it's alphabetized under H.
