Plants

In plants, the term "sting" is normally used as a verb, but occasionally used as a noun refer to urticating hairs; sharp-pointed hollow hairs seated on a gland which secretes an acrid fluid, as in nettles. The points of these hairs are brittle and break off easily, leaving a sharp point like a hypodermic needle, through which the fluid is injected.

    Plants a hope.
