Which type of Hydrocotyle is this?

[Atxpunx]

Is there a way to tell? Is there one type more common than normal? Any info would be greatly appreciated. Also, can it be planted, or is it best to allow it to root? Thank you again.

Any help please? I'm new to Hydrocotyle and would like to know how to use it. Thanks
