Characteristics of Japanese Linden Tree (Tilia japonica) in the Wild

Tilia japonica
Japanese linden or Japanese lime (Tilia japonica) is a species of deciduous tree native to Japan. This tree grows in the mountains to an altitude of 2,000 m asl.

Tilia japonica is the official tree of the city of Nagano, Japan.

At first glance, it resembles Tilia cordata, but it differs in having 164 chromosomes instead of 82, and by some subtle differences in leaf and flower morphology. The inflorescences of Tilia japonica consistently have 5 staminodes, which is a reliable trait to distinguish it from Tilia cordata and Tilia amurensis. Recent studies have shown that Tilia japonica plays an important role in maintaining ectomycorrhizal tissue in local forests growing in Japan.
