Rhododendron tsusiophyllum

Rhododendron tsusiophyllum (syn. Tsusiophyllum tanakae) is a species of flowering plant in the family Ericaceae, native to Japan. An evergreen shrub reaching 0.3 m, it is typically found growing about 500 m above sea level on southern Honshu and nearby smaller islands, such as the Izus. It is markedly different from other members of the genus Rhododendron in flower morphology and was once placed in its own genus, Tsusiophyllum.
