When I put together the seed list I cut and paste the names directly from World Flora Online https://www.worldfloraonline.org/ <https://www.worldfloraonline.org/>.  As of now the name they list for this plant is Dichelostemma capitatum so that’s what I used.  I have to use something as my authority and that’s what I’ve decided it will be. World Flora Online  is a well respected source for plants names.  Many plant names are in flux these days and different authorities will use different names.  I’m not trained in taxonomy nor do I have the time or energy to go into the weeds on taxonomy hence my decision to stick with one naming source.  

The bottom line is I will be sticking with Dichelostemma capitatum until such time as World Flora Online changes the name. 

It’s fine if someone wants to post additional information, as Mary Sue has done,  about naming controversies but I’m staying out of the arguments.  Most of the time a quick google search will reveal any recently used names anyway.

Club 39: 111 (1912), and that is what the Jepson Manual, the authority on California plants is now calling it along with Plants of the World Online and iNaturalist. However, the Flora of North America is still including it under Dichelostemma capitatum, but since I've been working on the wiki I have noticed that source to be very slow in updating "bulb" names when they are changed. And World Flora Online has not updated it either.  I don't know what other states where it grows are calling it. So some people have submitted corms and seed under one name and some under the other.

It you are interested in reading the paper where the change was proposed here is the link:
