I asked Joe Kunisch at one of the orchid shows if he remembered which it might be, but he didn't really know. I don't think he's ever put clonal names on his mexipediums. I think it was four or five years ago, when he was trying all of his paphs and all in semi-hydro culture. under lights in his basement, his mexi seedlings were growing quite well but since he keeps things quite cool in winter and at nights, things didn't fare well
