Elm, also known as Ulmus, white elm, white Ulmus, zero elm, Ulmus, Ulmus tree, home elm, spring elm, sticky elm, sky-reaching elm, money elm. It is a deciduous tree that can grow up to 25 meters tall with a diameter of 1 meter. In barren areas, it grows into a shrub-like form. The bark of young trees is smooth, gray-brown or light gray, while the bark of mature trees is dark gray, irregularly deeply fissured, and rough. The small branches are either hairless or hairy, pale yellow-gray, pale brown-gray, or gray, sparsely pale brown-yellow or yellow, with scattered pores but no enlarged cork layer or raised cork wings. The winter buds are nearly spherical or ovate, with the back of the bud scales being hairless and the edges of the inner bud scales having long white soft hairs. The leaves are elliptic-ovate, lanceolate, elliptic-lanceolate, or ovate-lanceolate, 2-8 cm long and 1.2-3.5 cm wide, gradually pointed or long-pointed at the tip, oblique or nearly symmetrical at the base, wedge-shaped to round on one side, and round to semi-heart-shaped on the other side. The leaf surface is smooth and hairless, with short soft hairs when young, later becoming hairless or with clusters of hairs at the vein axils, and the edges have heavy serrations or single serrations. There are 9-16 pairs of lateral veins on each side, and the leaf stalk is 4-10 mm long, usually with short soft hairs only on the upper side. The flowers bloom before the leaves, clustered in the leaf axils of last year's branches. The winged fruit is nearly circular, rarely ovoid-circular, 1.2-2 cm long, with the top end of the notch on the column head surface being hairy, and the rest being hairless. The fruit kernel is partially located in the middle of the winged fruit, not close to or close to the notch at the top, and its color is the same as the winged fruit before and after ripening, initially light green, later white-yellow. The persistent floral cover is hairless, with 4 shallow lobes, and the edges of the lobes are hairy. The fruit stalk is shorter than the floral cover, 1-2 mm long, with short soft hairs (or rarely none). The flowering and fruiting period is from March to June (later in the northeast).
