Sal Tree
Shorea robusta
サラソウジュ
An evergreen tree in the Dipterocarpaceae. Famous in Buddhism as the sacred tree under which Buddha entered parinirvana. In Japanese temples, however, trees labeled 'sala' are usually Stewartia pseudocamellia, not the true sal tree. Native to India and Southeast Asia.
