Note.

Lectotypification of Plectranthus hockii De Wild. De Wildeman (1913 b) cited two syntypes, i. e. A. Hock s. n. (syntype BR [ BR 0000008109453 ]; isosyntype K), DR. Congo, Haut-Katanga, bords de la Dilemba, 1911 & A. Hock s. n. (syntype BR [ BR 0000006263287 ]), Plateau de Shinkwari (Manika), 1911. The specimen [ BR 0000008109453 ] departs somewhat from the protologue in having the pedicel glabrous under the joint (protologue: “ breviter tomentoso ”), while [ BR 0000006263287 ] is slightly puberulous below the joint; moreover, [ BR 0000006263287 ] has a thick woody rootstock, quite typical of the species; it is selected as the lectotype.
