Ulmus crassifolia Nutt., the 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 [2]; it also occurs in northeastern Mexico. They typically grow 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 - 5 cm long and 1.3 - 2 cm broad, with an oblique base; leaf fall is late in the year, often in early winter. The 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]. The species is extremely rare in cultivation in Europe [1], and is uncommon in Australasia [2].
