The leaves of this Elm tree are alternately configured. The serrations at the margin are single or double, normally pointed at the tip and asymmetrical towards the base.   This is a hermaphroditic genus, whose blossoms are ideal and petal-less. The flowers are generally pollinated by the wind, even though they are also visited by bees. This round shaped Samara fruit is dispersed by air currents and they go red with chlorophyll, which is the process of photosynthesis prior to the emerging of leaves. All the varieties of this tree tolerate extensive varieties of soil and level of pH, except some of them that require proper drainage.
