To quote one page:
"There is but one great all-round warm-water aquarium "anacharis" formerly of the genus " Elodea" now Egeria...
...the common name "anacharis" used to be a valid genus name for some of these plants; and is a moniker still often used. The correct scientific name for most species of "anacharis" is Elodea ("Ell-oh-dee-ah"). Egeria is another recent (1961) erected genus for a similar plant (the one of most interest to aquarists) that produces 2 to 4 flowers ( Elodea only 1), that have large and deeply white petals (versus small and colorless), and are pollinated by insects (elodeas is done via water)."
A picture and the full article, with a pic of Elodea flowers, can be found here.
So basically, Elodea was the genus name for anacharis, but that has changed, and the biological supply company may be behind the times, or sending a cold water elodea species... but going by the pics its probibly just anacharis.
