Ecotypes or phenotypic plasticity-The aquatic and terrestrial forms of (Apiaceae).

Morphological and ecological differences of two forms of are known and described in the literature: aquatic and terrestrial. However, their taxonomic status is currently unknown. The question whether they are genotypically adapted to specific environmental conditions or are those differences a result of phenotypic plasticity is addressed in this study.
