Hydrocharitaceae [FNA22, HC, HC2]
Frogbit Family, Naiad Family, or Water-nymph Family, Tapegrass Family, Waterweed Family
Origin: Native
Notes: FNA editors insisted on following Cronquist (1981) in recognizing Najadaceae, and the author's introduction to Najadaceae in FNA (Haynes 2000) protested Cronquist's treatment was outdated, citing recent papers investigating seed coat (Shaffer-Fehre 1991) and molecular relationships (Les & Haynes 1995). That evidence places Najadaceae within Hydrocharitaceae. Here we combine the two, as in JPM.
