Description
Habitus of full-grown plants
Lapsana communis is an annual[6] or perennial herbaceous plant growing to 1–1.2m (3ft 3in– 3ft 11in) tall, with erect, hairy branching stems and clear (not milky) sap. The leaves are alternate and spirally arranged; the larger leaves at the base of the flowering stem are often pinnate, with a large oval terminal leaflet and one to four small side leaflets, while smaller leaves higher on the stem are simple oval; all leaves have toothed margins. The flowers are yellow, produced in a capitulum 1–2cm (0.39–0.79in) diameter, the capitula being numerous in loose clusters at the top of the stem.[7][8] The capitulum is surrounded by a whorl of involucral bracts, the outer ones very small and the inner ones erect, narrow and stiff and all the same length. The eight to fifteen florets are all ligulate[6] and pale yellow, shaped like a tongue with a five-toothed tip. Each has five stamens and a gynoecium composed of two fused carpels. The fruit is a cypsela surrounded by the hardened remains of the involucral bracts. The numerous small seeds are retained in the cypsela until the plant is shaken by the wind or a passing animal.[9] Pappus is absent.[6]

Distribution and habitat
Away from its native area, Lapsana communis is common throughout the British Isles,[12] naturalised, and sometimes considered an invasive species, in many areas around the world, including Australia,[13] Chile,[14] New Zealand,[15] Greenland,[16] and most of Canada and the United States.[16]
Lapsana communis is found growing in arable fields, woods, hedges,[6] roadsides, wasteland, hedgerows, woodland margins and clear-felled areas in forests.[9]
Cultivation and uses
The young leaves are edible, and can be used in salads or cooked like spinach.[17] Because of its tiny hairs, some might prefer it mixed with other vegetables.[18] The scientific name comes from lapsane, an edible herb described by Marcus Terentius Varro of ancient Rome. The English name 'nipplewort' derives from its closed flower buds[verification needed], which resemble nipples. Because of its resemblance to nipples, under the doctrine of signatures it was once used as treatment for breast ulcers.[19]
