Plectranthus, with some 350 species, is a genus of warm-climate plants occurring largely in the southern hemisphere, in sub-Saharan Africa, Madagascar, India and the Indonesian archipelago down to Australia and some Pacific Islands.

 Several species are grown as ornamental plants, as leaf vegetables, as root vegetables for their edible tubers, or as medicine.
Nephrolepis is a genus of about 30 species of ferns in the family Nephrolepidaceae (or Dryopteridaceae in some classifications).
Solenostemon, commonly known as "Coleus" is a genus of flowering plants in the family Lamiaceae.
 Several species formerly included have been moved to the genus "Plectranthus".
 They are native to tropical Africa, Asia and Australia.
 Some species are cultivated for their highly variegated leaves.
Coleus is a former genus of flowering plants in the family Lamiaceae.
 In recent classifications, the genus is no longer recognized, and the formerly included species are instead placed in the genera "Plectranthus" and "Solenostemon".
 Because the type species, Coleus amboinicus ("Plectranthus amboinicus") is now placed in "Plectranthus", "Coleus" is regarded as a synonym of "Plectranthus".
 The term "coleus" is often used as a common name for species formerly placed in the genus "Coleus" that are cultivated as ornamental plants, particularly Coleus blumei ("Plectranthus scutellarioides"), which is popular as a garden plant for its brightly colored foliage.
