Monograph of the genus elodea (hydrocharitaceae): part 2. the species found in the andes and western south america

The genus Elodea Richard in Michaux was first published in 1803(Fl. Bor.-Am. 1: 20, 1803), based upon the single species. E. Canadensis from Montreal, Quebec, Canada. Though this was stated to have perfect flowers, it is now certain that the holotype specimens and the plants in nature are dioecious....
