Acer Campestre - Description

Description

It is a deciduous tree reaching 15–25 m tall, with a trunk up to 1 m in diameter, with finely fissured, often somewhat corky bark. The shoots are brown, with dark brown winter buds. The leaves are in opposite pairs, 5–16 cm long (including the 3–9 cm petiole) and 5–10 cm broad, with five blunt, rounded lobes with a smooth margin. Usually monoecious, the flowers are produced in spring at the same time as the leaves open, yellow-green, in erect clusters 4–6 cm across, and are insect-pollinated. The fruit is a samara with two winged achenes aligned at 180°, each achene is 8–10 mm wide, flat, with a 2 cm wing.

The two varieties, not accepted as distinct by all authorities, are:

  • A. campestre var. campestre - downy fruit
  • A. campestre var. leiocarpum (Opiz) Wallr. (syn. A. campestre subsp. leiocarpum) - hairless fruit

The closely related Acer miyabei replaces it in eastern Asia.

  • Field maple flowers

  • Field maple in autumn, France

  • Field maple, Germany

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)

    Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.
    Elaine Heffner (20th century)

    I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.
    Henry David Thoreau (1817–1862)
