Great, Dave.
I have found so many contorted species names, it is mind boggling.
Those lists are the only way one can sort things out into some semblance of order.
Even sellers mislabel and misspell the daffodil species bulb names they sell and then the grower thinks that is what he is growing.
Because that name might have been valid 200 years ago, then the whole issue of verifying what it actually IS comes up.
