Growing mostly in wet areas it also causes an itching skin rash but it is less severe than poison-ivy and disappears in about 24 hours. Note the opposite leaves with sharp serrations along the edge. Close examination will reveal the hypodermic like needles which break off and inject a histamine and actyl choline to cause the rash.
