Ulmus crassifolia Nutt., the Texas Cedar Elm or simply Cedar Elm, is a deciduous tree native to south central North America, mainly in southern and eastern Texas, eastern Oklahoma, Arkansas and Louisiana, with small populations in western Mississippi, southwest Tennessee and northwestern Florida [1]; it also occurs in northeastern Mexico [1] [2]. The tree typically grows well in flat river bottom areas referred to as Cedar Elm Flats.
The Cedar Elm is a medium-sized to large deciduous tree growing to 24-27 m tall with a rounded crown. The leaves are small, 2.5 cm - 5 cm long by 1.3 cm - 2 cm broad, with an oblique base, and distinguish it from Ulmus serotina with which it readily hybridizes in the wild. Leaf fall is late in the year, often in early winter. The wind-pollinated apetalous perfect flowers are produced in the late summer or early fall; they are small and inconspicuous, with a reddish-purple color. The fruit is a small winged samara 8 - 10 mm long, maturing quickly after the flowering in late fall [3] [4].
