fringed false buckwheat, Fallopia cilinode

A confusion of names? What to do about it? It's a goal of science to have one agreed name for each kind of living thing. And let's do it in a dead language so no one gets jealous? Cool! That should work. But if Andre in Hackensack, who died in 1802, publishes the name as Polygonum cilinode in 1803, how can someone in Paris know what to call it when they see a specimen? Or will they invent another name. Fast forwarding to modern times, communication is no issue. And science can analyze like never before. But someone still needs to decide where to draw the lines between genera and species. Should this be Polygonum, or Bilderdykia, or Reynoutria, or Tiniaria, or Fallopia? Fallopia does seem to be carrying the day, even though USDA still calls it Polygonum. So Fallopia ciliinodis! Oops! Did somebody at the International Plant Name Index just add an extra letter with their fat fingers? Stuff happens.
