ニレ科TreeDeciduousMountainAinu cultureTimber

A deciduous tree in the elm family, distributed from Hokkaidō and northern Honshū through the Korean peninsula, Northeast China, and eastern Siberia. Distinguished from other elms by the leaf tip splitting into 3–7 shallow lobes. The inner-bark fibre is the traditional material for the Ainu 'attus' bark-fibre robe, still produced as a craft. The wood is used for timber and implements. Winged samaras appear in spring before the leaves expand.
