About

Tilia amurensis, commonly known as the Amur lime or Amur linden, is a species of Tilia native to eastern Asia. It differs from the better-known Tilia cordata in having somewhat smaller leaves, bracts, and cymes. It is an important timber tree in Russia, China, and Korea, and is occasionally planted as a street tree in cities with colder climates.
