Syn. Coreopsis palmata

Anacis palmata (Nutt) Z.H.Feng, Z.J.Huang & Su Liu is now the accepted scientific name for this species. It was named as such by Zhen Hao Feng, Zhang Jie Huang, and Su Liu in Phytotaxa in 2024. It was first named and described as Coreopsis palmata by Thomas Nuttall in The Genera of North American Plants in 1818.

DNA testing proved Coreopsis palmata did not belong the Coreopsis genus. They found this species was more closely related to species in the Bidens (Beggarticks) genus. Six closely related species were moved (one of those returned) to the resurrected Anacis genus. 

The genus, Anacis Schrank, was named and described as such by Franz von Paula von Schrank in Denkschriften der Königlich Akademie der Wissenschaften zu München in 1817.

Now, as of 7-12-26 when this page was written, Plants of the World Online lists 6 species in the Anacis genus. It is a member of the plant family Asteraceae with 1,714 genera. Those numbers could change as updates are made on POWO.

The above distribution map for Anacis palmata is from Plants of the World Online. Areas in green are where the species is native. The map on the USDA Plants Database for Coreopsis palmata is similar.

The map on iNaturalist shows where members have made observations. Anyone can join and it is a great website to confirm and share your observations. The maps on iNaturalist are continually updated as members post new observations. I post all my observations on iNaturalist. The iNaturalist community accepted the name change and all observations of Coreopsis palmata will be changed to Anacis palmata soon.

THERE ARE SEVERAL LINKS AT THE BOTTOM OF THE PAGE FOR FURTHER READING AND TO HELP WITH A POSITIVE ID.

I was first introduced to the Lordi Marker and Drover’s Prairies by a friend of mine on June 8 in 2026. I was really amazed by all the wildflowers and took a lot of photos of new to me species. One of those species was Coreopsis palmata which I found in both prairies. When I started writing this page, I found out the name changed to Anacis palmata… You never know, it may change back again or to another genus…

 

 

The flowers of the Prairie Coreopsis at the Lordi Marker Prairie were fairly faded by 6-8-28, but they were better at Drover’s Prairie.

 

 

Much better flowers at Drover’s, but there weren’t that many. Just a few scattered colonies here and there.

I think I messed up… The above photo and one below are possibly Coreopsis grandiflora... In fact I’m pretty sure. The last photo was from a different plant, so I’m pretty sure it is Anacis palmata.  There were several colonies and I took photos  in several areas.

 

I will be going back to the prairies again soon to take more photos…

I live on the family farm in Windsor, Missouri in Pettis County (Henry County is across the street, and Benton and Johnson aren’t far away). I have grown over 500 different plants and identified over 250 species of wildflowers (most have pages listed on the right side of the page). I am not an expert, botanist, or horticulturalist. I just like growing, photographing, and writing about my experience. I rely on several websites for ID and a few horticulturalists I contact if I cannot figure them out. Wildflowers can be variable from location to location, so that can be a bit confusing. If you see I have made an error, please let me know so I can correct what I have written.

I hope you found this page useful and be sure to check the links below for more information. They were written by experts and they have provided much more information. Some sites may not be up-to-date but they are always a work in progress. If you can, I would appreciate it if you would click on the “Like” below and leave a comment. It helps us bloggers stay motivated. You can also send an email to me at thebelmontrooster@yahoo.com. I would enjoy hearing from you especially if you notice something is a bit whacky.

NOTE: The data (figures, maps, accepted names, etc.) may not match on these websites. It depends on when and how they make updates and when their sources make updates. Some websites have hundreds and even many thousands of species to keep up with. Accepted scientific names change periodically and it can be hard to keep with as well. Some of the links may use a name that is a synonym on other sites. In my opinion, Plants of the World Online by Kew is one of the most reliable and up-to-date plant databases and they make updates regularly. I make updates “at least” once a year and when I write new pages or add new photos but I do get behind. We are all a work in progress. 🙂
