Hydrocotyle prolifera Kellogg, Proc. Calif. Acad. Sci. 1: 15 1854. (syn: Hydrocotyle australis Coult. & Rose; Hydrocotyle canbyi Coult. & Rose; Hydrocotyle polystachya var. triradiata A. Rich.; Hydrocotyle verticillata var. triradiata (A. Rich.) Fern.);
USA (Alabama, Arkansas, Arizona, California, District of Columbia, Delaware, Florida, Georgia, Louisiana, Massachusetts, Maryland, Mississippi, North Carolina, New Jersey, Nevada, Oklahoma, South Carolina, Texas, Utah, Virginia), Cuba as per Catalogue of life;

Small weed seen growing wild.

Seems to be Hydrocotyle Species.

Hydrocotyle sibthorpioides Lam.


Looks different from Hydrocotyle sibthorpioides Lam. as per comparative images at Hydrocotyle
Appears close to Hydrocotyle verticillata Thunb., but is different.
I think it may be Hydrocotyle prolifera Kellogg as per GBIF

Right …!
