Acer campestre, known as the field maple, is a flowering plant species in the soapberry and lychee family Sapindaceae. It is native to much of Europe, the British Isles, southwest Asia from Turkey to the Caucasus, and north Africa in the Atlas Mountains. It has been widely planted, and is introduced outside its native range in Europe and areas of USA and Western Australia with suitable climate.
It is a deciduous tree reaching 15–25 m (49–82 ft) tall, with a trunk up to 1 m (3 ft 3 in) 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 (2.0–6.3 in) long (including the 3–9 cm (1.2–3.5 in) petiole) and 5–10 cm (2.0–3.9 in) 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 (1.6–2.4 in) across, and are insect-pollinated. The fruit is a samara with two winged achenes aligned at 180°, each achene is 8–10 mm (0.31–0.39 in) wide, flat, with a 2 cm (0.79 in) wing.
The two varieties, not accepted as distinct by all authorities, are:

The native range of field maple includes much of Europe, including Denmark, Poland and Belarus, England north to southern Scotland (where it is the only native maple), southwest Asia from Turkey to the Caucasus, and north Africa in the Atlas Mountains. In many areas, the original native range is obscured by widespread planting and introductions. In North America it is known as hedge maple and in Australia, it is sometimes called common maple. In Nottinghamshire, England it was known locally as dog oak.
