Plectranthinae notes
Created 18/07/2022
These are my current overarching notes which I have posted here for reference.
Context in Lamiaceae
The list below shows the genera in Lamiaceae, for Southern Africa (i.e. SA, Lesotho, eSwatini, Namibia, Botswana, Zimbabwe & southern Mozambique), highighting the position of the Plectranthinae relative to other taxonomic groupings (but not showing any phylogenetic information beyond the groupings.
In general the list shows the cumulative number of native genera. In the case of the Plectranthinae the number of species is also shown. These are only indicative numbers and may need to be updated to take into account a few fringe genera or taxonomic duplication/omission. At the same time, the aim of this is not to be a conspectus of the Lamiaceae and so the focus will be on ensuring the data are complete for the Plectranthinae specifically.
The total number of Southern African species (not including hybrids) in the Plectranthinae according to my current survey is 128, apportioned as below.

Zooming in on the Plectranthinae
In the case of the other Lamiaceae, the listed genera exclude those which correspond to introduced, naturalised or otherwise exotic species. For the Plectranthinae, however, I have tried to also keep track of those species which might readily be encountered so that the identification can be made clear. This includes species such as Coleus barbatus, C. scutellaroides or C. amboinicus. I have noticed before that some synonyms have snuck in so this is a working list which I will want to update from time to time.
