Description
By the age of ten years, the tree bears a close resemblance to the American Elm U. americana, but will never approach the latter's size. The tree can reach a height of 17 m, with a slender trunk rarely exceeding 0.4 m d.b.h; the bark is longitudinally fissured, and dark grey in colour. The twigs often develop corky wings that may persist for several years. The leaves are usually obovate < 9 cm long by 5 cm broad (significantly smaller on juvenile trees) and chiefly characterized by their thick, leathery texture and obtusely doubly or simply toothed margins. The perfect, wind-pollinated apetalous flowers appear from March until May. As implied by its name, U. macrocarpa is distinguished by its large, orbicular, wafer-like samarae < 50 mm in diameter, which ripen in May and June.

Famous quotes containing the word description:
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
