An image of this flower was previously posted here, and I called it Swink's St. John's-wort. This is an image from my more recent visit to that spot. It has wider leaves than most Kalm's St. John's-worts, but based on more careful measurements, I now tend to think it is Kalm's. I guess I allowed myself to be seduced by the fun of thinking I found something new and rare. Now I repent, will remove it from this site, and share my mea culpa with others that have those older images.
