It is customary on the wiki when the decision is made to accept the renaming of a genus or species (which isn't done immediately waiting for some time to see if the proposed change is accepted) to keep the old name and link on the old page to the new name. So on the Zigadenus wiki page there is a link to the species now listed on the Toxicoscordion page. Even if some of the species are poisonous, they are so pretty and Toxicoscordion is such an ominous sounding name that I wish they had come up with a better name. The wiki was created and maintained by volunteers so whether this always happens depends on someone taking the time to add the links. As David Pilling has said a number of times there is a lot of work that could be done on the wiki by new volunteers. Mary Sue
