List Of Rhododendron Species

This List of ''Rhododendron'' species includes species of the genus ''Rhododendron'', which is in the plant family Ericaceae. Depending on the source, there are anywhere from 800 to over 1,100 wild species. The vast majority of ''Rhododendron'' species are native to the eastern Himalaya and southeast Tibet, along with the islands of Java, Sumatra, Borneo, New Guinea, and the Philippines. The rest are broadly spread throughout the northern hemisphere in relatively small isolated populations, including Japan, northwestern North America, the Appalachian, and the Caucasus Mountains.

''Rhododendron'' has eight traditionally accepted subgenera based on morphology, still the consensus taxonomy used by most authorities: '' Azaleastrum''; '' Candidastrum''; '' Hymenanthes''; '' Mumeazalea''; '' Pentanthera''; ''Rhododendron''; '' Therorhodion''; ''Tsutsusi''. ''Hymenanthes'', with approximately 225 species, and subgenus ''Rhododendron'', with approx. 400 species, comprise what gardeners typically describe as "Rhododendrons." Two subgenera are generally known to gardeners as "Azaleas", and include many fewer true species: ''Pentanthera'', which comprises the deciduous azaleas, and ''Tsutsusi'', which includes evergreen azaleas.

Modern cladistic analysis, based on nuclear genetics, proposes changes in the classification of species within subgenera. These proposals are based on at least three different studies, with no changes proposed within subgenus ''Rhododendron'' and its sections. The major proposed changes are: to make section ''Choniastrum'' (originally in subgenus ''Azaleastrum'') a separate ''Choniastrum'' subgenus; to combine sections ''Ponticum'', ''Pentanthera'', and the species ''Rhododendron canadense'' in subgenus ''Hymenanthes''; subgenus ''Azaleastrum'' to include the former subgenera ''Tsutsusi'', ''Mumeazalea'', ''Candidastrum'', and ''Menziesa'', along with former sections ''Viscidula'', ''Azaleastrum'', ''Sciadorhodion'', and the species ''Rhododendron vaseyi''.
