Hornbeam – Carpinus caroliniana

The County of Amiens (also: Amiénois) was a feudal state centred on the city of Amiens, northern France, that existed from the 9th century until 1077 when the last count became a monk and the county reverted to the French crown. In 1185 the county was united with the French crown under King Philip II of France.^[1]
