Alberto, your comment on "Tristagma peregrinans is a Ravenna's species that we could not find so far. He does not recognize Ipheion as a genus simply because if all were Tristagmas the botanical names should bear his name attached. If this is botanical science.!! " makes me chuckle. It is amazing what a mess he has made down there! A botanist could spend his entire career cleaning up after him! Have you ever been to Herbarium Ravennae, his personal holdings of his many "Type" specimens? Tchau, Kevin D. Preuss http://www.amaryllis-plus.com/
