Contributo alla conoscenza della flora vascolare endemica di Toscana ed aree contermini. 6. Hypericum hircinum subsp. hircinum (Hypericaceae)

The distribution of Hypericum hircinum subsp. hircinum in Tuscany is reported by the analysis herbarium specimens, bibliographic references and records in the field. Hypericum hircinum subsp. hircinum is confirmed to be endemic to the Sardinian-Corsican biogeographic province including the Tuscan Archipelago, while H. hircinum subsp. majus is widespread along the Italian peninsula and we show that all H. hircinum records for continental Tuscany, Liguria and Lazio should be referred to the subsp. majus.
