During a floristic survey of Khar-Us Lake and its associated wetlands in Khovd Province, we found seven species and two hybrid nothospecies that have not previously been recorded in Mongolia. These taxa were found in seven localities and included Hydrilla verticillata (L.f.) Royle, Najas flexilis (Willd.) Rostk. & W.L.E. Schmidt, N. minor All., and N. tenuissima (A.Braun ex Magnus) Magnus (Hydrocaritaceae); Potamogeton ×angustifolius J. Presl (Potamogetonaceae); Ceratophyllum platyacanthum Cham. subsp. oryzetorum (Kom.) Les (Ceratophyllaceae); Aldrovanda vesiculosa L. (Droseraceae); Veronica anagalloides Guss. (Plantaginaceae); and Utricularia ×japonica Makino (Lentibulariaceae). Two of these genera, Hydrilla Rich. and Aldrovanda L., were also newly recorded from Mongolia. The addition of these taxa to the present Mongolian flora list brings the numbers of registered taxa and genera to 3,200 and 686, respectively. The morphological characteristics, diagnostic features, and distribution of these taxa in Mongolia are described in this report.
