Family Ulmaceae. Occurs in the wild in eastern Transbaikalia, in the Far East, in Mongolia, northern China and Japan.

A large, handsome tree up to 35 m high, with a straight, even trunk of regular form and a dense, widely spreading crown. The bark of old trees is whitish, on the shoots brown, smooth, sometimes with corky outgrowths, which greatly adorn the plant when leafless. Young shoots are densely pubescent, buds dark brown. Leaves obovate, with an asymmetrical base and a short petiole, double- or triple-serrated at the margin. The leaf blade is rough-pubescent above, downy beneath. In spring the leaves are green, in summer dark green, lighter beneath; in autumn brownish-red, chestnut-brown, dark raspberry, whitish beneath. Small reddish flowers in clusters. The samarae are yellow-brown.

Grows quickly, surpassing other elms in this respect, tolerates shading, is frost-hardy, develops well on light-textured soils; in urban conditions it tends to tip dieback, and is completely unaffected by "Dutch elm disease". Easily propagated by seed and by root suckers.

Ornamental from the beginning of leafing until leaf fall. Especially striking in autumn foliage, in solitary and group plantings. For its ornamental qualities, rapid growth, tolerance to external conditions, and resistance to the lethal "Dutch elm disease" affecting elms, it deserves wider use in green landscaping. In cultivation since 1895.

Has two forms with corky outgrowths: with smooth leaves - (f. laevis suberosa) and with sharply rough leaves - (f. scabra suberosa). There is also a dwarf form with rough leaves and winged corky outgrowths on the branches - (f. nana scabra suberosa).
