Are Costus and Boenninghausenia plants both found in the Americas?
Boenninghausenia Boenninghausenia is a monotypic plant genus in the family Rutaceae. The sole species is Boenninghausenia albiflora, which occurs in Bhutan, Nepal, Pakistan, Kashmir, India, Indonesia, Philippines, Myanmar, Thailand, Laos, North Vietnam, China and Japan.
Coleus 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.
