Ulmus Serotina - Description

Description

Rarely exceeding 20 m in height, the tree has a rounded crown with spreading to pendulous branches. The glabrous young shoots become progressively corky-winged with age, and bear oblong to obovate leaves < 8 cm long. The wind-pollinated apetalous perfect flowers form pendulous racemes which open in September and serve to distinguish the species from its compatriot, the Cedar Elm U. crassifolia, with which it readily hybridizes. The samarae are oblong - elliptical, 10 mm to 15 mm in length, deeply divided at the apex, and ripen in November .

Famous quotes containing the word description:

    It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.
    Ludwig Wittgenstein (1889–1951)

    The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.
    Guy Debord (b. 1931)

    It [Egypt] has more wonders in it than any other country in the world and provides more works that defy description than any other place.
    Herodotus (c. 484–424 B.C.)
