Seed germination reports for Sicilian endemic taxa of the genus Helichrysum (Asteraceae)

In the present study, successful germination protocols for 11 different taxa of the genus Helichrysum native to Sicily are discussed. Eight of them are representative of strict endemic Sicilian taxa, 2 are Italian sub endemic and one, namely H. stoechas, is a widespread W Mediterranean species. Given the controversial taxonomic status and relationships of the Mediterranean Helichrysum, the taxonomic approach enhancing the existing diversity of Sicilian populations was herein adopted from current literature. First germination records are given for some of the investigated taxa.
