Phenotypic variability in Scutellaria brevibracteata subsp. icarica on the Ikaria Island (Eastern Aegean).

The aim of this work is to highlight the phenotypic variability of Scutellaria brevibracteata subsp. icarica on the Aegean Island of Ikaria. While studying the various subpopulations of S. brevibracteata subsp. icarica found on the Island at different altitudes and in different locations, it has been found that the phenotypic expression of this species is strongly linked to the type of substrate and to terrestrial and atmospheric water sources. In particular, the subpopulation from the southwestern part of the Island that grows on granite soil has manifested several unique features that clearly distinguish it from the other Ikarian subpopulations, and which could justify assigning it to a particular ecotype.
