Acer campestre
Field maple

- Family: Aceraceae
- Origen: native to Europe, including the British Isles

This tree can reach 10 to 15 metres in height, with a twisted trunk and grey bark split into rectangular flakes.

Opposite deciduous leaves, 4 to 12 centimetres long, with an almost leather consistency, palmate, with 3 or 5 uneven lobes, with the one in the centre often trilobed. They are dark green in colour on the upper surface, with the underside more pallid and pubescent, with groups of hairs over the veins. In autumn, before the leaves fall, they turn yellow, gold and red.

Small greenish-yellow hermaphrodite flowers arranged in erect clusters.

The fruit is disamara, growing in clusters of 4, with green or reddish wings that do not narrow at the base, but widen lightly at the apex, open at a 180º angle, 2 to 4 centimetres long.

It exudes a white milky fluid when the petioles are broken.
