The closest wild relative of cultivated lettuce. The leaves grow along a spiny stem and get progressively smaller as they reach its top. They emit latex when cut. Many flowers are produced and usually appear in the upper part of the plant. It is known as the compass plant because in the Sun the upper leaves twist round to hold their margins upright. It is native to Europe, Asia, and north Africa, and has become naturalized elsewhere.
