Citation: Whittemore, A.T. 2014. Ulmaceae for Flora of Missouri. Flora of Missouri. 1178-1192. Interpretive Summary: This contribution will form a section of the Flora of Missouri, a manual published by the State of Missouri (Department of Conservation) to provide up-to-date information on the taxonomy, distribution, and ecological status of all plants that are wild or invasive in Missouri, together with a guide for identification, aimed at professional and sophisticated amateur users. The taxonomy, distribution, and ecological status of all species of Ulmaceae that are wild or invasive in Missouri is reevaluated, based primarily on a thorough reexamination of available herbarium specimens, and a guide for identification is supplied. Eleven species in three genera are included. Two of the three genera are important in horticulture, and Ulmus contains both species that are very important horticulturally and species that are weedy and invasive in North America. Current and past economic importance of the species is briefly summarized, based on data from herbarium specimens and the scientific and trade literature. This contribution provides up-to-date information on the biology of this group of species, along with identification aids, including more than 2/3 of the species found in the United States. It will support accurate identification of important invasive exotic species, and it will promote the recognition and exploitation of native germplasm with promise for horticulture. It will be used by professional land managers, educators, conservationists, and sophisticated amateur botanists and horticulturalists, insuring that work on land management and conservation will be based on full, accurate and up-to-date information about the basic biology and relationships of these organisms, and providing a baseline for monitoring the status of several invasive species.
Technical Abstract: The family Ulmaceae is treated for the Flora of Missouri, a detailed floristic manual for the state published by the Missouri (State) Department of Conservation. Three genera and 11 species are recognized; full morphological descriptions, dichotomous keys, and brief summaries of geographical and ecological distribution, economic use, and taxonomic notes are given for each of them. Two of the three genera are used in horticulture, and Ulmus contains both species that are important horticulturally and species that are weedy and invasive in North America. This contribution will support accurate identification of important invasive exotic species, and it will promote the recognition and exploitation of native germplasm with considerable horticultural potential.
