  FAQ - Plants - Hydrocharitaceae
The family of plants, Hydrocharitaceae, comprises some of the most economically important plants in the world, both from positive viewpoints, and negative.
The remarkable thing about these plants, though, is that there is such a wide variety of forms within the family that even experienced aquarists might not know that they are in the same family.
As a group, Hydrocharitaceae comprises 15 genera, all of which are aquatic.

A phylogenetic analysis of Hydrocharitaceae was conducted using data from the internal transcribed spacers (ITS-1;2) of the nuclear ribosomal genes, the chloroplast gene rbcL and the flanking introns of the chloroplast matK gene.
The aquatic, monocotyledonous Hydrocharitaceae consist of 17 genera which are highly variable in habitat, pollination and morphology.
Currently, morphological and developmental characters within the Hydrocharitaceae are being investigated to supplement the molecular data for further investigation of relationships.

 Hydrilla verticillata--"The Perfect Aquatic Weed"
These fresh water and marine vascular plants, as a group, are particularly fascinating because of numerous adaptations they have evolved as they returned to the submersed environment.
One of the most studied aquatic vascular plants is hydrilla (Hydrilla verticillata (L.F.) Royle (Hydrocharitaceae)).
Hydrilla could easily be called the perfect aquatic plant because of the extensive adaptive attributes it possesses to survive in the aquatic habitat.
