Description

Molecular methods reveal new information on the range and recent history of four related and similar appearing species: Hydrilla verticillata, Egeria densa, Elodea canadensis, and Elodea nuttallii (family Hydrocharitaceae). We also distinguish monoecious from dioecious hydrilla for each of the hydrilla samples. We examined implications of the confirmed distribution relative to previous records and demonstrated the regional and national need for reverification of these species collected recently or as much as a half century ago. USGS National Research Program (NRP).
