[5] The leaves have fine hairs, are green at the bottom and shade to purplish at the top; they are 2–4 centimetres (3 ⁄ 4 – 1 + 1 ⁄ 2 in) long and broad, with a 1–2 cm petiole (leaf stalk), and wavy to serrated margins.
Urticating hairs of a stinging nettle. The most common form of urticating hairs in plants are typified by nettles, which possess sharp-pointed hollow bristles seated on a gland that secretes an acrid fluid. The points of these bristles usually break off in the wound, and the acrid fluid is pressed into it.
