Also known as "Poor Joe," this little plant in the coffee family (Rubiaceae) can be quite common in dry sandy sites that are open and disturbed. I first noticed it in the mid- 1980's while exploring with Ken Klick and Sandy O'Brien. None of us recognized it, so Ken and Sandy ran it through Swink and Wilhelm's keys to the families and genera.
They worked together and did this out loud, showing a remarkable understanding of the language of botany and its myriad descriptive terms. They arrived at
Diodia teres var.
setifera without ever looking at a picture! It was an excellent lesson in the value of botanical keys, the most accurate way to identify an unknown plant. Thanks Ken and Sandy for providing me with the impetus to learn the language of botany all those years ago! Photographed near Knox, Indiana.
