The opposite leaves are sessile. At the bottom they are broadly rounded or have a heart-shaped border. At the front they are drawn out into a sharp, triangular point. The leaf margin is sharply serrated. The triangular tip and the edge of the leaf are somewhat reminiscent of the leaves of stinging nettles , this leads to the scientific epithet and their common name .
