[Taxacom] Plant names

[Hubert Turner]

Another useful on-line resource is: WFO (2021): World Flora Online. http://www.worldfloraonline.org.
WFO lists Reynoutria as an accepted genus name.

    As I understand it, Reynoutria is the generally accepted genus from recent literature. From a global perspective, Plants of the World Online is quite helpful and often up-to-date. For identification characters, FNA is a good resource, but the Polygonaceae treatment was published in 2005 when Fallopia was thought an appropriate genus for knotweed: http://beta.floranorthamerica.org/Fallopia

    I would advise against using Polygonum cuspidatum, as listed by the USDA, since that reflects an old concept of Polygonum s.lat. I am not aware of any recent debate concerning the use of Reynoutria.
