Ranunculus hispidus Michx. is the accepted scientific name for this species of Ranunculus. It was named and described as such by André Michaux in Flore Boreali-Americana in 1803.

Accepted Infraspecific Names (2) (Updated on 12-15-21): Ranunculus hispidus var. caricetorum (Greene) T.Duncan, *Ranunculus hispidus var. hispidus (autonym). *When infraspecific taxon are named, an autonym (“type-specimen”) is automatically generated whose description is closest to the (original) species. They all have their own synonyms… Ranunculus hispidus var. nitidus is now a synonym of Ranunculus carolinianus 

The genus, Ranunculus L., was described by Carl Linnaeus in the first volume of the first edition of Species Plantarum in 1753.

As of 12-15-21 when this page was last updated, Plants of the World Online by Kew lists 1,682 species in the Ranunculus genus. It is a member of the plant family Ranunculaceae with 50 genera. Those numbers could change as updates are made on POWO.

The above distribution map for Ranunculus hispidus is from Plants of the World Online and includes the species and subordinate taxon. Areas in green are where they are native. The map on the USDA Plants Database is different because it also shows Ranunculus hispidus var. nitidus which is now a synonym of Ranunculus carolinianus. You can find maps for the subordinate taxon by clicking on the links for both websites.

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. You can find maps for intraspecific taxon by typing their names in the search box.

Ranunculus hispidus is common on the farm in a few areas. Many Ranunculus species can be quite tricky to identify but I think I have identified five here. I didn’t get the Ranunculus hispidus properly identified until 2021. Am I sure? That is a secret. I am still working on a few “iffy” colonies…

Ranunculus hispidus includes the variety R. hispidus var. caricetorum which is also found in Missouri along with R. hispidus var. hispidus… Autonyms used to confuse me A LOT! To make it simple, the species is Ranunculus hispidus has “certain” characteristics that separate it from all other members in the genus. The variety, R. hispidus var. caricetorum has “subtle” differences from the species. Ranunculus hispidus var. hispidus was named R. hispidus until var. caricetorum came along… Along the line, other taxa became synonyms of one or the other or even of other species.

I apologize for not writing descriptions at the moment. I am busy updating the plant pages, adding photos I took over the summer, and writing pages for newly identified species. This is a wintertime project… I will go back later and add descriptions as I have time. There are several links at the bottom of the page written by experts that know much more than I do. Writing descriptions of the plant, flowers, stems, leaves, etc. is a lengthy process and I get behind. 🙂

I have enjoyed photographing and learning about the many wildflowers growing on the farm and other areas. My farm is 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 100 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 somewhat variable from location to location, so sometimes it gets 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 provide 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 the most reliable and up-to-date plant database and they make updates on a regular basis. 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. 🙂
