Phylogeny and evolution
The first molecular phylogeny of the aquatic genus of 50 species discerned three clades: Clade A (three species, widespread); Clade C (10 species, New World); Clade D (six species, Europe).

Phylogenetic studies in ''Callitriche'': implications for interpretation of ecological, karyological and pollination system evolution
'' Aquatic Botany'' 68: 123-141 The parsimony analyses revealed that aneuploid reduction (n=5 to 4) and polyploidy (n=5 to 10) have evolved at least twice in the genus, whereas the obligately submersed growth habit and hypohydrophily have evolved once.
