+'''Elms''' are [[deciduous]] and [[semi-deciduous]] [[tree]]s comprising the genus ''Ulmus'', family [[Ulmaceae]].
+
+Elm [[leaves]] are alternate, with simple, single- or, most commonly, [[leaf shape|doubly-serrate]] margins, usually [[asymmetric]] at the base and [[acuminate]] at the [[wikt:apex|apex]]. The genus is [[hermaphroditic]], having [[Plant sexuality#Individual_reproductive_unit_.28a_flower_in_angiosperms.29|perfect flower]]s which, being wind-pollinated, are [[apetalous]]. The fruit is a round wind-dispersed [[samara (fruit)|samara]]. All species are tolerant of a wide range of soils and [[pH]] levels but, with few exceptions, demand good drainage.

===Pests and diseases===
===Pests and diseases===
−'''Dutch elm disease''' devastated elms throughout Europe and North America in the second half of the 20th century. It is caused by a micro-[[fungus]] transmitted by two species of ''[[Scolytinae|Scolytus]]'' elm-bark [[beetle]] which act as [[Vector (epidemiology)|vector]]s. The disease affects all species of elm native to North America and Europe, but many Asiatic species have anti-fungal genes and are resistant.
