This paper presents the results of a research performed on Gargano Promontory (SE-Italy) on the populations ofScabiosa garganica, a species with little herbarium records and whose few morphological descriptions are outdated.S. garganicabelongs to theS. holosericeaaggr., a group including very similar taxa that still have different taxonomic classifications. Its typical location is Monte Sant’Angelo in the Gargano area. Surveys have ascertained the existence of many populations, whose stational data help to understand the distribution and ecological conditionsS. garganicais linked to. The morphological analysis of a large sample (75 plants from 9 sites) allows for the description of the qualitative and quantitative characteristics of this species. The new morphological framework highlights the species autonomy ofS. garganicaand can contribute to clarifying the relationship withS. holosericeaandS. taygeteato which it is closer. In addition, for the correct delimitation of the species, the nameScabiosa garganicais lectotypified. Finally, the species was assessed against the IUCN criteria for the evaluation of its conservation status.
