Croton glandulosus L. is the correct and accepted scientific name for this species of Croton. The genus and species were named and described as such by Carl von Linnaeus in the second volume of the first edition of Species Plantarum in 1753.  

Accepted infraspecific names (6) (Updated on 5-8-21): Croton glandulosus var. arenicola (Small) B.W.van Ee, P.E.Berry & Ginzbarg, Croton glandulosus var. floridanus (A.M.Ferguson) R.W.Long, *Croton glandulosus var. glandulosus (autonym), Croton glandulosus var. lindheimeri Müll.Arg., Croton glandulosus var. pubentissimus Croizat, Croton glandulosus var. septentrionalis Müll.Arg.. *When infraspecific taxon are named, an autonym (“type-specimen”) is automatically generated (autonym) whose description is closest to the (original) species.

Croton glandulosus var. septentrionalis was named and described as such by Johannes (Jean) Müller Argoviensis in Prodromus Systematis Naturalis Regni Vegetabilis in 1966.

Plants of the World Online by Kew lists 1,149 species in the Croton genus (as of 5-8-21 when I last updated this page). It is a member of the plant family Euphorbiaceae with 227 genera. Those numbers could change as updates are made.

The above distribution map for Croton glandulosus var. septentrionalis is from Plants of the World Online. The map on the USDA Plants Database for the United States is similar. There are six varieties of Croton glandulosus with the type specimen (C. glandulosus var. glandulosus) being found in southern Mexico through mid South America. Croton glandulosus var. septentrionalis has the widest range in the United States and Mexico and is the only C. glandulosus found in Missouri. 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. However, in this case, many observations of Croton glandulosus are actually Croton glandulosus var. septentrionalis.

Croton glandulosus var. septentrionalis (Sand Croton) on 9-8-18, #504-23.

I took these photos from a few plants I found growing in one small area in the pasture in the back of the farm. The farm is in Pettis County in west-central Missouri. Henry County is across the street. The pasture was used for hay in 2019 and 2020 so I didn’t get to check on this plant until after the hay was cut. Unfortunately, I didn’t see any but maybe I will in 2021.

I apologize for not writing descriptions at the moment, but I have A LOT of wildflower pages to make and publish before I start getting too busy. I update this site and add new pages over the winter but I didn’t get finished. SO, I decided to just make the page with photos and links to other sites for better plant ID. I will be taking more photos over the summer and posting but I will also be working on these pages as I have time.

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 figures may not match on these websites. It depends on when and how they make updates and when their sources make updates (and if they update their sources or even read what they say). 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. 🙂
