Alberto, I have a new Ph.D student from Chile named Nicolás Garcia, who is working on the Hippeastreae, molecular and morphological studies, using many different genes. I think you can expect an accurate generic circumscription of this group in the years to come. "That certain someone" (he who shall remain nameless) has made a mess of what used to be Rhodophiala and Zephyranthes. So far, we can safely say 1) Rhodolirion is a good genus and is more cloesly related to Placea and Phycella than Rhodophiala sensu stricto. Rhodoliron include R. montanum ( syn. Rhodophiala rhodolirion), R. laetum, and some others. 2) the core Rhodophiala from Chile are monophyletic and are closely related to Famatina (which will probably be submerged in Rhodophiala). Alan
