Synonyms of Elephantopus carolinianus (5) )Updated on 5-11-21): Elephantopus carolinianus f. vestitus Fernald, Elephantopus carolinianus var. violaceus (Sch.Bip.) C.F.Baker, Elephantopus flexuosus Raf., Elephantopus scaber var. carolinianus (Raeusch.) Kuntze, Elephantopus violaceus Sch.Bip.

Elephantopus carolinianus Raeusch. is the correct and accepted scientific name for this species of Elephantopus. It was named and described as such by Ernst Adolf Raeuschel in Nomenclator Botanicus in 1797.

The genus, Elephantopus L., was named and described as such by Carl von Linnaeus in Species Plantarum in 1753. 

Plants of the World Online by Kew lists 22 accepted species in the genus Elephantopus (as of when I last updated this page on 5-11-21). It is a member of the plant family Asteraceae with 1,671 genera. Those numbers could change as updates are made (and likely will).

Elephantopus carolinianus ( Leafy Elephant’s Foot) on 9-9-19, #627-2.

I remember it well… I was running down a wooded hillside toward a creek helping a friend herd cattle at his mother’s farm on September 9, 2019. She had sold the farm and the cows needed to be moved to another location. I had been on top of the hill admiring all the Perilla frutescens (Beefsteak Plant) that were growing by the thousands! I only have a few on my farm just a few miles away so I was amazed (somewhat). Anyway, the cows started coming so I had to bolt down the hill toward the creek. On the way down the hill, running fast as my 58-year-old legs would go, trying to run through the vegetation and vines, I almost tripped because I spotted a plant I hadn’t seen before. I didn’t have time to stop and look because I needed to head off the cows so they would go where we wanted them to instead of where they wanted to. You know what I am talking about if you have ever tried to drive cows… There is more to the story, but you can read about in the post I wrote, Elephantopus caroliniansis and Perilla frutescens Observed, on September 9.

Anyway, once the cows were where we needed them to be, I went back to the hillside to look for the plant and take photos (I remembered to take the camera). I found the plant I was looking for with no problem because there were a lot of them and I took a lot of photos. Later on, when I went back home I identified the plant as Elephantopsis caroliniansis.

Anyway, even though I first observed this plant and took these photos on September 9 (2019), I didn’t officially start writing this page until March 16, 2020. I usually use the winter months to catch up on writing and updating plant pages.

Elephantopus carolinianus ( Leafy Elephant’s Foot) on 9-9-19, #627-3.

The first plant I started taking photos of didn’t have any open flowers… Then I found some after I started looking around a bit.

Before I started using the drag-and-drop feature on iNaturalist, I was identifying the wildflowers I had found on the Missouri Plants website. Reading and understanding the botanical terminology then rewriting in my own words can be somewhat difficult. Click on the link and you will see what I mean.

COMPLICATED PLANTS DESERVE COMPLICATED DESCRIPTIONS…

I could easily say the plant stems end in a cluster of flowers but that wouldn’t do this plant justice. It is definitely a complicated plant that deserves a complicated description… One may choose to start from the ground up but I am sort of backward in that regard. I first take photos of the whole plant followed by the flowers, leaves then the stems. I never know how much knowledge about plant anatomy readers may have,  so I may tend to think I have a lot of explaining to do. Actually, I have to explain it to myself first…

The flower stems end in a cluster of flower heads that are compact or unusually compressed. Close to the top of the stem is a leaf with another 3 1/2-4″ of stem above it. Then there are 3 leaves (foliaceous bracts) which the flower clusters sit on. Bracts and peduncles have short hairs.

A few terms you might see…

Bract=A leaf-like structure at the base of a flower or flower head.
Involucre=Series or set of bracts that surround a flower or cluster of flowers. Sometimes only one surrounds the whole cluster of flowers.
Phyllary=An involucral bract.
Peduncle=A single flower stalk.

Hmmm… Let’s take a closer look. The above photo shows the three foliaceous bracts with a cluster of involucral bracts from which flowers emerge… An involucre is a bract (phyllary) or set of bracts (phyllaries) that surround a flower or cluster of flowers. In this case, I believe there is something a little strange going on…

The above photo is a plant with open flowers…

Elephantopus carolinianus ( Leafy Elephant’s Foot) on 9-9-19, #627-6.

The flowers are rather strange. Although this plant is a member of the Asteraceae (Composite) family, the flowers are not “daisy-like”. They only have disc flowers. I also find that strange because “disc” flowers are normally in the center and the “ray flowers” are what we think of as petals also known as florets. GEEZ!

Hmmm… Something is a bit odd…

In layman’s terms, Missouri Plants says the corollas (another name for petals) are lilac to whitish and are irregularly 5-lobed. The flower emerges from the phyllariesWAIT A MINUTE! Take a closer look at that mass of petals… Something is weird!

How many flowers do you see? One? Count again… I see at least four.

I don’t mean four flowers in the entire photo… Of course, there are four. I mean how many do you see per flower… Each bract has a set of four loose phyllaries (actually 2 pairs of 2) in which 4-5 flowers emerge from. Have you ever seen a Fan Flower (Scaevola sp.) where the petals are on only on half the flower? I think that’s what is going on here…

Photo of a single involucre separated to reveal four flowers. This photo was retrieved from the Arkansas Native Plant Society website. The article, “Know Your Native’s-Carolia Elephant’s-Foot” was written and the photo was taken by ANPS member Sid Vogelpohl. Retrieved on March 16, 2020.

While I was looking for websites to link to this page for further reading, I found this great post on the Arkansas Native Plant Society site. You know what they say… A picture is worth a thousand words. The article was written by ANPS member Sid Vogelpohl and he also took the photos. This is a great post as are all the posts on their site…

As I mentioned and the above photo clearly shows, each involucral bract produces 2 sets of 2 phyllaries from which 4-5 flowers emerge. The flowers fit together making them appear there is only one.

Lower leaves are quite large and “spatula-like”. One website says these lower leaves are 5″ long, but just guessing, I would say they are closer to at least 8″.

Elephantopus carolinianus ( Leafy Elephant’s Foot) on 9-9-19, #627-8.

The leaves grow in an “alternate” pattern along the stems and have no petioles (sessile-no stem). Missouri Plants says: “Alternate, sessile, elliptic to oblanceolate or spatulate, acute to acuminate, shallow serrate to crenate-serrate, slightly scabrous and pubescent below, sparse pubescent and shiny dark green above, to -30cm long, -10cm broad, tapering to base.” That is about 11″ long by about 4″ wide and the leaves attach directly to the stem with no petiole (sessile). Spatulate is a good word because the leaf could be considered like a spatula with a handle…

The plant’s upper leaves are MUCH smaller and kind of oval in shape. Here you can see this leaf is what is meant when Missouri Plants says: “Peduncles subtended by a single foliaceous bract.” This leaf is where the “inflorescence” begins and is part of it as the “single foliaceous bract.” At least that is my opinion. Subtended means “under” so it makes sense.

Besides a camera, I also need to remember to take the magnifying glass, a small notepad and pen… A field guide would also be promising. I haven’t normally been one to bring plants home from other locations, but I am really tempted with this one. I saw this plant again while I was helping Jay at either his farm or in the backyard of his mothers (the one she sold). Apparently, this plant is fairly common in that neck of the woods.

Elephantopus carolinianus ( Leafy Elephant’s Foot) on 9-9-19, #627-11.

I think I read somewhere that the bracts contain a single seed that doesn’t fall out. The whole bract falls off with the seed still inside.

I was fairly busy during the summer in 2020 and didn’t do much wildflower hunting. Maybe I will find this species again somewhere in 2021. I will say, Elephantopsis carolinianus is one of the most interesting species I have ever run across.

Several weeks ago I was waking in the south hayfield and I noticed a plant with maroonish leaves. It had no flowers and I thought perhaps something was wrong with it because of the color of the leaves. I didn’t pay much attention to it at the time especially since I normally take photos of plants with flowers. Then, on October 12, I was walking through the middle of the south hayfield and I ran across another plant with maroonish leaves with flowers. I still thought the color of the leaves was a bit odd.

Elephantopus carolinianus (Leafy Elephant’s Foot) on 10-12-21, #843-10.

I didn’t recognize the plant from its flowers because they weren’t open at the time. Once I got back to the house and went through the photos, I uploaded most of the species I photographed on iNaturalist to record my observations.  For this one, I thought I had found a different species so I uploaded the first photo, entered my location, to see what was suggested. Hmmm… The ONLY species that was suggested was Elephantopsus carolinianus. I thought it was whacky! How could it be an Elephantopsus in the middle of the hayfield? SO, I uploaded the second photo and it said the same thing. Then a light came on! I have only seen those large leaft bracts on one species… It was indeed an Elephantopsus carolinianus! I have Leafy Elephant’s Foot in the south hayfield. I was not expecting that and I thought they would have been in the wooded areas rather than in the sun.

Elephantopus carolinianus (Leafy Elephant’s Foot) on 10-12-21, #843-11.

If I had taken a closer look at the basal leaves I may have realized what it was. Likely, they are a maroonish color because they are in full sun instead of shade.

Sorry this photo is somewhat blurry. I always take a lot of photos and weed out what I don’t want. Sometimes, I have to go out and take more later, which is what I will do. In this photo, though, you can see even the stems are a purplish color.

Elephantopus carolinianus (Leafy Elephant’s Foot) on 10-12-21, #843-13.

I will also have to go out again to see if the flowers will be open for a nice shot.

Elephantopus carolinianus (Leafy Elephant’s Foot) on 10-12-21, #843-14.

Information online says they flower July through October, so hopefully I can find this plant AGAIN… Sometimes I think I need to put up markers tall enough to see them. 🙂

I have enjoyed photographing and learning about the many wildflowers growing on the farm in Windsor, Missouri in Pettis County (Henry County is across the street) and other areas. The city limits is also across the street and the north and south side of the farm. I have grown over 500 different plants and most have pages listed on the right side of this site. 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 horticulturalist 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.

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. 🙂
