Currently Glandularia which POWO sinks into Verbena is our most 'observose' genus not in POWO.
I propose we maintain this Glandularia deviation for now (which means when there's duplicates like here swapping away from POWO e.g. Verbena lilacina -> Glandularia lilacina) so at least we've resolve the duplication, and then discussing whether we want to maintain the deviation (at the genus level) or not here: https://www.inaturalist.org/flags/405708
