Common along bank of Hunting Bayou near the Hunting Bayou overlook at Herman Brown Park.
Looks like I need the flower... But there may be mustard clues...
Not certain about the species. Based ID on location.
Maybe Solanum carolinense? As with a lot of Solanum, thorns are on all parts of the plant, including leaves.
Solanum carolinense, Carolina horsenettle is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States that has spread widely throughout North America. This plant has hard spines along the stems that can penetrate the skin and break off, causing much pain.
