What is the origin of the name, Variable watermilfoil? Haines and Crow and Hellquist don't assign a common name - athough they call the genus watermilfoil - Magee calls it Diverse leaved milfoil. Seems like there are all kinds of taxonomic difficulties associated with this plant - both in nomenclature and identification. Is there any kind of protocol for assigning common names?
