Capitanopsis oreophila

Capitanopsis oreophila, synonym Plectranthus bipinnatus, is a species of flowering plant in the family Lamiaceae. It was formerly treated as the only species, Perrierastrum oreophilum, in the genus "Perrierastrum". A phylogenetic study in 2018 found that it was embedded in the genus "Capitanopsis", and it was transferred to that genus. It is native to Madagascar.
Taxonomy.
The species was first described in 1930 by André Guillaumin, as "Perrierastrum oreophilum", the only species in his genus "Perrierastrum". In 2003, Alan James Paton decided that the genus should be sunk into "Plectranthus". As the name "Plectranthus oreophilus" had already been used (in 1912), Paton coined the replacement name "Plectranthus bipinnatus". A major study of the subtribe Plectranthinae in 2018 showed that "Plectranthus bipinnatus" was embedded in a clade containing the then three species of "Capitanopsis", so "P. bipinnatus" was transferred to "Capitanopsis" under the original epithet.
