Lactuca perennis L.
Synonymy
Taxon info
Lactuca perennis is known from only a few localities in NW Greece, growing in open woodland on rocky limestone slopes at 900–1500 m, but is otherwise fairly widespread in C & S Europe. The somewhat similar L. intricata (= L. graeca), also with blue ligules, occurs in mountains of Greece, S Albania and W & S Anatolia. It is a lower, intricately branched plant with greyish rather than black achenes.A
