Flowers containing 5 small white petals and form a raceme. The broad leaves have a serrated margin and a smooth feel to them.
Dicot. Key A. Plant neither climbing, twining, or trailing; stems of thick fleshy pads; leaves modified into needle-like spines. This is the only species under Cactaceae in our book. The locality of this specimen was on a plot of land off of Fall Creek Road in Lebanon.
I don't have the location where it was taken, but it was probably in Rutherford County or Williamson County. I think it might be a Green Frog.
