ID Request: possible arabidopsis variety …aquatic? images resized:
I have not been able to identify this plant. The overall shape makes me think it’s arabidopsis, but it’s smooth appearance doesn’t seem to align with most specimens online.
-Found dec 13th 2020 on the eastern coast of mid florida– Plants found growing in low lying often flooded area, with dark clay soil, some found growing on cypress knees.
-Largest rosette is approx 4 inches across
-leaves are smooth and delicate and flowers have 5 petals 

Closest I can suggest is Arabidopsis thaliana (L.) Heynh. !

Looks different from Arabidopsis thaliana
I doubt it is from this genus as the flower structure is different.
