To my knowledge there are only 3 or maybe 4 species of Rauhia: multiflora (syn. peruviana), decora and staminosa. There is a Eucrosia mirabilis, but in bloom and in leaf no one would confuse that with a Rauhia. I've never heard of the other so-called species. There are always a ton of misnamed plants at various markets so I would not place much emphasis on the names you've seen.....ask for a pic of the flower and go from there. If you want more info you can e-mail Alan Meerow, the worlds expert on these plants!! Best of luck :o) Dan
