Thermo-Mediterranean formations of headlands and peninsulas of Corsica and Sardinia dominated by cushion-forming spiny Genista corsica or Genista morisii. These endemic species participate in the constitution of hedgehog-heaths (unit F7.45) as well as in that of the coastal formations listed here, which assume an evident phrygana appearance; they may also enter in the composition of midelevation formations of less distinctive appearance which can be listed under unit F6.18.
