Thanks for the interesting comments about the naming of plants and thanks Dylan for alerting me to the crispa subspecies that I need to change on the wiki. The Manning and Goldblatt books rarely include much data about subspecies and they don't recognize a lot of them so I was using the spelling in the monograph, but will change it. IPNI lists it this way: Iridaceae Ferraria crispa Burm. subsp. nortieri M.P.de Vos -- J. S. African Bot. 45(3): 343 (1979), as 'nortierii'. (IK) From a practical standpoint it would be nice if someone checked the rules before accepting the way someone names a plant so it would not have to be changed down the road. The question I have is at what point does the plant community decide to change all their labels if someone named a plant and did not follow the naming rules and countless books have been written in the meantime using that spelling and everyone knows it by that spelling. In the case of the species in question as I originally wrote, except for the Kew checklist, almost all of the other references use the other spelling. IPNI: Iridaceae Ferraria densepunctulata M.P.de Vos -- J. S. African Bot. 45(3): 346 (1979). (IK) And Christiaan van Schalkwyk has alerted me to another super reference that I'm going to find very helpful, an African plants database, and I found this reference there. http://ville-ge.ch/musinfo/bd/… Mary Sue
