Clear phylogeographical structures shed light on the origin and dispersal of the aquatic boreal plant Hippuris vulgaris
Aquatic plants are an important ecological group in the arctic flora; however, their evolutionary histories remain largely unknown.

Aquatic plants are an important ecological group in the arctic flora; however, their evolutionary histories remain largely unknown.
