|---|---|---|---|---|---|
| Ulmaceae | Ulmus ×intermedia | Hybrid Elm | Recognizable from its intermediacy between its parents and occurrence in proximity to both. This hybrid apparently occurs in many midwestern States (cited for Iowa, Illinois, Kansas, Minnesota, Nebraska, South Dakota, Texas) (Elowsky, Jordon-Thaden, & Kaul 2013); the increasingly common naturalization of U. pumila in our area, and its proximity to populations of U. rubra would seem to make it inevitable that this hybrid occurs in our area. | ||
| Ulmaceae | Ulmus alata | Winged Elm, Wahoo | Rock outcrops, dry and mesic forests and woodlands, bottomlands, old fields, disturbed areas. | N. Virginia west to Missouri, south to c. peninsular Florida and c. Texas. |  (c) Campos, Aidan |
| Ulmaceae | Ulmus americana var. americana | American Elm, White Elm | Swamps, bottomland forests, moist slopes, especially on relatively or strongly nutrient-rich substrates. | Nova Scotia, New Brunswick, and Québec west to se. Saskatchewan, south to n. Florida, c. Texas, and n. and c. Mexico. |  (c) Marcum, Paul |
| Ulmaceae | Ulmus americana var. floridana | Florida Elm | Shell middens, other calcareous forests. | Se. North Carolina (north at least to Carteret County) south to c. peninsular Florida, west to Panhandle Florida and s. Alabama (H. Horne, pers. comm., 2013). |  (c) Horn, Jay - CC-BY |
| Ulmaceae | Ulmus crassifolia | Cedar Elm, Olmo | Bottomland forests, hardwood flatwoods, prairies with tight soils; rarely river bluffs and ravines. | W. Tennessee, s. Missouri, and Oklahoma south to Mississippi, Louisiana, Texas, and Mexico (Coahuila, Nuevo León, Tamaulipas); disjunct in the Big Bend portion of n. Florida and n. peninsular Florida. |  (c) Wong, Michelle - CC-BY |
| Ulmaceae | Ulmus glabra | Wych Elm, Scotch Elm | Suburban woodlands. | Native of Europe. Naturalized in ne. United States; reported from Virginia and District of Columbia (Sherman-Broyles in FNA 1997), but may only be cultivated. |  (c) Danielson, Erik |
| Ulmaceae | Ulmus minor | English Elm, English Cork Elm | Planted horticulturally, rarely spreading. | Native of Europe. |  (c) Weakley, Alan - CC0 |
| Ulmaceae | Ulmus parvifolia | Chinese Elm, Lacebark Elm | Disturbed secondary forests, roadsides, fencerows, old fields, other disturbed areas. | Native of China and Japan. The bark on mature trees exfoliates creating a patchwork of gray, brown, green, and orange blotches. |  (c) Fleming, Gary P. |
| Ulmaceae | Ulmus procera | ||||
| Ulmaceae | Ulmus pumila | Siberian Elm, Dwarf Elm | Roadsides, disturbed areas. | Native of Asia. |  (c) Danielson, Erik |
| Ulmaceae | Ulmus rubra | Slippery Elm, Red Elm, Orme Gras (frc) | Moist to fairly dry calcareous forests, rich bottomlands, rich cove forests in the low Mountains. | Maine, Québec, and Ontario west to Minnesota and North Dakota, south to Panhandle Florida and c. Texas. |  (c) Fleming, Gary P. |
| Ulmaceae | Ulmus serotina | September Elm, Red Elm | Dry-mesic to mesic upland forests, bottomland and riparian forests, stream banks, bluffs, lake and pond margins, flatwoods; especially over limestone. | Kentucky, s. Illinois, and e. Oklahoma south to e. Tennessee, nw. Georgia, Alabama, and Mississippi; allegedly disjunct in ne. Mexico (Coahuila and Nuevo León) (Villaseñor 2016). Rugel collected this species on the French Broad River in 1842, the location attributed to North Carolina by Mohr (1901). |  (c) J. Kevin, England - C, permission granted to NCBG |
| Ulmaceae | Ulmus thomasii | Cork Elm, Rock Elm | Mesic upland and riparian forests, shaded bluffs, especially over limestone. | Québec to Minnesota and Nebraska, south to New Jersey, Maryland, West Virginia, Kentucky, Tennessee (?), Arkansas, and Kansas. Ulmus thomasii has historically been considered to be present in c. Tennessee, but all known previous reports are false or not definitively identifiable. |  (c) rboles - CC-BY |
