Dave, When adding or editing a plant name is it possible to add a scroll over window or something to list preferred abbreviations for species or synonym names? We get duplication due to different accepted abbreviations.
Tropicos uses subsp., f., var.
Kew uses subsp., fo., var.
ITIS uses ssp.,
ex.
subspecies = subsp. and ssp. used
forma = f. and fo. used
varietas = var.
