The Elm family consists of a handful of trees and shrubs in the eastern and southern parts of the country, some of which are planted elsewhere as ornamentals. The leaves are simple and alternate, but often a little bit asymmetrical at the base. The flowers are bisexual in the elms and unisexual in the other genera. There are 4 or 8 separate sepals and 0 petals, plus 4 to 8 stamens. The ovary is positioned superior and consists of 2 united carpels (bicarpellate) forming a single chamber. It matures as a winged seed or a drupe (a fleshy fruit with a stony pit).
Key Words: Trees and shrubs with simple leaves asymmetrical at the base.
