"This large deciduous tree grows to 30 m or more and is a native of the Balkan Peninsula. The large palmately-compound leaves with 5-8 toothed leaflets are distinctive throughout the summer. Thick twigs, fat sticky buds and opposite pairs of leaf scars are prominent winter features.....The fruits develop in the autumn and are covered with blunt spines....The fruits are poisonous and should not be confused with the edible chestnus (Castanea)."
