Note.

Coleus maculosus is variable in petiole length, leaf blade shape and corolla length. Earlier authors (e. g. Robyns (1947): Troupin and Ayobangira (1985)), recognised three taxa: a taxon with large corolla and oblong sessile leaves (corresponding to the type specimen of Coleus edulis Vatke ), a taxon with large corolla and ovate petiolate leaves (type of Coleus fimbriatus Lebrun & L. Touss. ) and a taxon with small corolla and ovate petiolate leaves (type of Plectranthus punctatus L’Hér. ). Recent authors, however, give priority to corolla size and recognise only two subspecies; we follow this treatment, but further work is needed.
