Can anyone identify this vine? The leaf shape is variable, ranging from circles to elongated ellipses. Usually in leaves of three, sometimes just one. Sometimes the elongated leaves have a lighter pattern within the center from the leaf.
We are located in south Florida.
Please see attached pictures. Thank you.

Yes, they are Desmodium
Cute little blooms & then the seed is a pain! It's stiffly hairy & sticks to any fabric as well as shoes, pet fur, you name it. Hitchikers! Very difficult to eradicate.

My first thought was also Desmodium. We have Sand Tick Trefoil (Desmodium lineatum) growing here in the Daytona Beach area.
