Swamp Azalea (Rhododendron viscosum (L.) Torr.)

Also known as Texas azalea; also classified as Rhododendron oblongifolium (Small) Millais.

Although the USDA and some other authorities consider the Texas azalea, Rhododendron oblongifolium (Small) Millais, to be a separate species, we have merged it into this species in keeping with the treatment of BONAP, POWO, and many others. Some authors treat it as a subspecies but we do not, as neither BONAP nor POWO recognize it as such.
