One of mine is round ruffled leaves and one is three tiny leaves which could possibly be frogbite, but not sure as it is still so small, and the spiney plant is growing in the clay, not floating, It's actually planted. I have several pieces but none have leaves just spines going in all directions.This is it with my lotus stems and roots. Look into the water to see it. It is just stems going out all directions.You had this one in your pot also.
