Rhododendron maximum — its common names include great laurel, great rhododendron, rosebay rhododendron, American rhododendron and big rhododendron — is a species of "Rhododendron" native to the Appalachians of eastern North America, from Alabama north to coastal Nova Scotia.
Rhododendron minus, the Piedmont rhododendron, is a rhododendron species native to Tennessee, North Carolina, South Carolina, Georgia, and Alabama.
 It has two subspecies: "Rhododendron minus" var.
 "chapmanii" and "Rhododendron minus" var.
 "minus" (the latter also known as "Rhododendron carolinianum").
Phytophthora kernoviae is a plant pathogen that mainly infects European beech ("Fagus sylvatica") and "Rhododendron ponticum".
 It was first identified in 2003 in Cornwall, UK when scientists were surveying for the presence of "Phytophthora ramorum".
 This made it the third new "Phytophthora" species to be found in the UK in a decade.
 It was named "Phytophthora kernoviae", after the ancient name for Cornwall, Kernow.
 It causes large stem lesions on beech and necrosis of stems and leaves of "Rhododendron ponticum".
 It is self-fertile.
 It has also been isolated from "Quercus robur" and "Liriodendron tulipifera".
 The original paper describing the species, stated it can infect "Magnolia" and "Camellia" species, "Pieris formosa", "Gevuina avellana", "Michelia doltsopa" and "Quercus ilex".
 Since then many other plants have been identified as natural hosts of the pathogen.
 Molecular analysis has revealed that an infection on "Pinus radiata", recorded in New Zealand in 1950, was caused by "P. kernoviae".
