I'm sorry, Tin. I was sure everyone would recognise that "zydvonia" is a non-existent, magical plant. They used to live wherever my grandfather went because the mysterious, elusiva zydvonia was the only plant he recognised. This invisible plant has been accepted into my family for so long that I do forget that not everyone shares our knowledge or realizes its a joke. I apologise, sincerely. Hope you didn't do any researching of this thing. OTOH, if you do find some reference to this fantasy PLEASE let me know.
