Considered by some authorities, particularly in Japan, to be a separate species, Acer amoenum (O momiji is the Japanese name), listed here by the name accepted by Western experts. The leaves are larger than ssp. palmatum, with usually seven lobes divided approx half way to the centre of the leaf, with finely and evenly toothed margins. Samaras also larger than ssp. palmatum. Cultivars showing characteristics typical of ameonum include 'Osakazuki', 'Ichigyoji' and 'Saoshika'. Tree in picture photographed at Westonbirt Arboretum, spring 2009.
