Family containing 15 genera of trees and shrubs distributed primarily throughout temperate regions, having watery sap and leaves that alternate along the stem. The leaves usually have toothed edges and often are lopsided at the base. The flowers lack petals. Male and female flowers are borne together or apart on the same plant. The fruit, a samara, may be winged, fleshy, or nutlike. In earlier classifications, the family was placed in the former order Urticales.

Genus containing around18 species of forest, timber, and ornamental shade trees native primarily to North Temperate areas. Many are cultivated for their height and attractive foliage. Prior to the industrial revolution, elms were also used as water pipes and in water pumps in large cities because they are durable in water. From 1925 to the mid 20th century, many of the native European and North American elms were killed by the Dutch elm disease. These trees are now being replaced by the disease resistant Chinese elm. Elm leaves are doubly toothed and often lopsided at the base. The petalless flowers appear before the leaves and are borne in clusters on jointed stems. The nutlike fruit, surrounded by a flat, sometimes hairy, winglike structure, is called a samara.

Species of tall, deciduous tree that grew widely in the eastern half of North America, and was popularly used for lumber, shade, and ornamentation prior to the 1930's. The hard, tough coarse-grain wood was also used for ship building because it bends well and does not splinter. Dutch elm disease, a fungus carried by the elm-leaf beetle, has systematically killed many of these trees.

Species of elm native to China but now found throughout the world as an ornamental, having small, lustrous leaves and interesting mottled bark.

Species of tall, fast-growing European elm, found mainly in England and Wales; before the advent of Dutch elm disease, it was one of the most common deciduous trees in Europe. It probably originated in Italy or Turkey: a survey of genetic diversity in Spain, Italy and Britain shows that all of this species are genetically identical clones of a single tree, probably brought to the British Isles by Romans for the purpose of supporting and training vines.

Species of elm native to the northeastern United States, similar to American elm in general appearance, but more closely related to the European wych elm, which has a very similar flower structure. It has a gluelike substance in the inner bark, which was formerly steeped in water as a remedy for throat ailments, powdered for use in poultices, and chewed as a thirst-quencher.

Slow-growing species of elm native to North America from Ontario and Quebec to Tennessee, Kansas, and Minnesota, having hard, heavy wood used for various products, and twigs that often develop corky ridges.

An enhanced technique of liquid chromatography that can be used to analyze particles that are smaller than 2-microns in size. Pumps used in UHPLC or UPLC systems operate above 6,000 PSI, which is typically the upper limit of conventional HPLCs. The technique was first patented in 2004 by Waters with the trademarked acronym “UPLC.”
