Thanks to Alan Meerow for providing more information about Pyrolirion. I've added the tribe information to the wiki for the members of the tribe, Eustephieae, which besides Pyrolirion also includes Chlidanthus, Eustephia, and Hieronymiella. If you take a look at these different genera you will find that although they are sisters, they don't look alike. In fact many of the species we have pictured on the wiki look more like other genera in the Amaryllidaceae family. This no doubt adds to the confusion when these plants are first seen and may explain why the Pyrolirion species Alessandro added to the wiki has been called Cooperia and Zephyranthes and why this genus has been described as being related to Habranthus. You can access these genera on the wiki to see what I mean from the Pyrolirion wiki page. Open each in another tab (in Windows, hold down the control key when you click on the link to the next genus). It is no doubt done differently with a Mac. Then just click on each tab one by one in each tab to look at the pictures. Since we just have one species illustrated for each of the four this is easy to do. http://pacificbulbsociety.org/pbswiki/index.php/… Mary Sue
