Henning's Rhododendron & Azaleas Pages
When Linnaeus created the botanical grouping called genus Rhododendron in 1753, he created a separate genus for Azalea containing 6 species. In 1796 Salisbury pointed out that Azalea and Rhododendron could not be maintained as distinct genera. In 1834, George Don subdivided the genus Rhododendron into 8 sections which are still recognized today. Azalea comprise two of these sections, Subgenus Pentanthera typified by Rhododendron nudiflorum and Subgenus Tsutsusi typified by Rhododendron Tsutsusi.
