Did you just pick up some fruit on a walk? To avoid confusion between chestnut and chestnut and thus poisoning, observe the tree from which the fruit comes:
- If the tree is in a wood, a forest or an orchard: it is very often a chestnut.
- If the tree is located in the city, in a park, in an alley or in the courtyard of a school: it is very often a chestnut tree.
Appearance of the leaves
- If the leaves of the tree are simple, without leaflets, elongated with sharp teeth: it is a chestnut.
- If the leaves of the tree are palmate with 5 (or 7) leaflets (small leaves which form a compound leaf, with a “webbed” appearance): this is a chestnut tree.
