It was named and described as such by Julius (Aloysius) Nieuwland in American Midland Naturalist in 1914. It was previously named and described as Campanula perfoliata by Carl von Linnaeus in the first volume of the first edition of Species Plantarum in 1753.

The genus, Triodanis Raf., was named and described by Constantine Samuel Rafinesque in New Flora and Botany of North America in 1838.

Plants of the World Online by Kew lists 6 species in the Triodanis genus (as of 5-24-21 when this page was last updated. It is a member of the plant family Campanulaceae with 89 genera. Those numbers could change as updates are made by POWO.

The above distribution map for Triodanis perfoliata is from Plants of the World Online. Areas in green are where the species is native and blue where it has been introduced. The map on the USDA Plants Database is similar but doesn’t include the state of Nevada.

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.

I was walking along the edge of the back pasture on May 24 in 2020 and stumpled upon a neat plant I hadn’t noticed before. It was only 6-8″ tall and it would have been very easy to overlook growing in tall grass. Unfortunately, there were no flowers left, just remains of what was. The light green, rounded, clasping leaves were enough to identify the species as Triodanis perfoliata commonly known as the Clasping Venus Looking Glass.

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.

On farther down, there are more photos of observations in 2021…

<<<<2021>>>>

I walked to the back of the farm on May 24 in 2021 mainly to see if I could find any Triodanis perfoliata where I had seen  the plant in 2020. Unfortunately, there were none to be found…

THEN ON JUNE 15…

I had bought a new camera so I was anxious to give it a work out even though it was getting late. At about 8:30 as I was getting ready to cross from the southeast corner of the back part of the farm into the south hayfield, I looked down and LOW AN BEHOLD there was single Triodanis perfoliata! Unfortunately, it had no flowers. As in 2020, the flowers had already ran their course.

THEN ON JUNE 16…

After I took the above photos on June 15, I walked along the sough side of the south hayfield and took several more photos. The light was brighter in that area so I was able to get a few more shots before walking back to the house. It became so dark the photos of a few species had to be retaken. SO, on the 16th, I went back to the south hayfield. I looked down after entering the area and HOLY CRAP! There were A LOT of Triodanis perfoliata, and some still had flowers!!!

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 (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. 🙂
