A rare plant of the rock pinelands of Miami-Dade County and the Keys. Also found in Texas.
Florida false buttonweed has glabrous or scabrous stems and leaves. The calyx has four nearly equal solid green lobes. The fruits are 1-2 mm long.
I could find very little about this species and no photos, so I was not able to do a comparison of my photographs to help verify the correct identification. If anyone can confirm or correct the proper species for these photographs, I would very much like to hear from you. Contact information can be found on the Contact Page.


Spermacoce keyensis is a member of the Rubiaceae - Madder family.
