I don't know.

I take some perverse pleasure at the way plants seem determined to undermine every naming scheme or genus-species categorization. When I dug into Brassicas, almost everything used to be called something else, and the experts keep changing their minds even about what is or isn't the same species.
As if the plants were reading botany textbooks and laughing "Oh, THAT'S what you think, is it??!?? Well, analyze THIS!!". Then they go out and make some kind of wacky hybrid cross that contradicts whatever the most recent sytem was.
