Extra information:

The name 'tigerstedtii' honours Dr. Carl Gustav Tigerstedt.
(1886-1957), Helsinki, Finland. Nationality: Finnish. 

In 1931, arboretum Mustila in S-E Finland received rhododendron seeds from Korea.
Dr. Tigerstedt started to use the name R. koreanum aff. brachycarpum, but never officially described it.
