Peter Hoch and Quinn Long.
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.
A weed we found in a neighbor's yard... Looks like small green tomatoes with thorns.
It was starting to rain pretty good now, so we had to cut the trip a bit short. Nonetheless, still quite fun. :)
Thorny hairy underside leaf. alternate lobed leaves. 5 petals and stamen
Plant growing in urban habitat. First plant picture after I arrived in Baltimore, on the way from Lexington Market to Inner Harbor.
