Not to be confused with Euphorbia peplis, Purple spurge, a relatively rare plant of coastal sand and shingle.
FONTE IMMAGINE: http://en.wikipedia.org/wiki/File:E_peplus.jpg
Euphorbia peplus (Petty spurge, Radium weed or Cancer weed) is a species of Euphorbia, native to most of Europe, northern Africa, and western Asia, where it typically grows in cultivated arable land, gardens, and other disturbed land.
It is an annual plant growing to between 5–30 cm tall (most plants growing as weeds of cultivation tend towards the smaller end), with smooth hairless stems. The leaves are oval-acute, 1–3 cm long, with a smooth margin. It has green flowers in three-rayed umbels. The glands, typical of the Euphorbiacae, are kidney-shaped with long thin horns.
The milky latex sap is toxic, and used as a therapeutic agent for the removal of warts and sunspots on the skin. Recent work also suggests that it may also be effective in treating superficial basal cell carcinomas.
Outside of its native range it is very widely naturalised and often invasive, including in Australia, New Zealand, North America, and other countries in temperate and sub-tropical regions.

From Wikipedia, the free encyclopedia
Euphorbia is a genus of plants belonging to the family Euphorbiaceae. Consisting of about 2160 species, Euphorbia is one of the most diverse genera in the plant kingdom, maybe exceeded only by Senecio . Members of the family and genus are sometimes referred to as Spurges. Euphorbia antiquorum and Euphorbia serrata are the type species for the genus Euphorbia, it was described by Linnaeus in 1753 in Species Plantarum. The genus is primarily found in the tropical and subtropical regions of Africa and the Americas, but also in temperate zones worldwide. Succulent species originate mostly from Africa, the Americas and Madagascar. There exists a wide range of insular species: on the Hawaiian Islands where spurges are collectively known as "akoko", and on the Canary Islands as "tabaibas".
The common name "spurge" derives from the Middle English/Old French espurge ("to purge"), due to the use of the plant's sap as a purgative.
The botanical name Euphorbia derives from Euphorbus, the Greek physician of king Juba II of Numidia (52-50 BC–23 AD). He is reported to have used a certain plant, possibly Resin Spurge (E. resinifera), as a herbal remedy when the king suffered from a swollen belly[verification needed]. Carolus Linnaeus assigned the name Euphorbia to the entire genus in the physician's honor.
Juba II himself was a noted patron of the arts and sciences and sponsored several expeditions and biological research. He also was a notable author, writing several scholarly and popular scientific works such as treatises on natural history or a best-selling traveller's guide to Arabia. Euphorbia regisjubae (King Juba's Euphorbia) was named to honor the king's contributions to natural history and his role in bringing the genus to notice.
The plants are annual or perennial herbs, woody shrubs or trees with a caustic, poisonous milky sap (latex). The roots are fine or thick and fleshy or tuberous. Many species are more or less succulent, thorny or unarmed. The main stem and mostly also the side arms of the succulent species are thick and fleshy, 15–91 cm (6–36 inches) tall. The deciduous leaves are opposite, alternate or in whorls. In succulent species the leaves are mostly small and short-lived. The stipules are mostly small, partly transformed into spines or glands, or missing.
Like all members of the family Euphorbiaceae, all spurges have unisexual flowers. In Euphorbia these are greatly reduced and grouped into pseudanthia called cyathia. The majority of species are monoecious (bearing male and female flowers on the same plant), although some are dioecious with male and female flowers occurring on different plants. It is not unusual for the central cyathia of a cyme to be purely male, and for lateral cyathia to carry both sexes. Sometimes young plants or those growing under unfavorable conditions are male only, and only produce female flowers in the cyathia with maturity or as growing conditions improve. The bracts are often leaf-like, sometimes brightly coloured and attractive, sometimes reduced to tiny scales. The fruits are three (rarely two) compartment capsules, sometimes fleshy but almost always ripening to a woody container that then splits open (explosively, see explosive dehiscence). The seeds are 4-angled, oval or spherical, and in some species have a caruncle.

Le Euphorbiaceae sono una famiglia di piante a fiore appartenente all'ordine delle Malpighiales, diffuse in tutti i climi, esclusi quelli artici.
Composta da 380 generi e 7.200 specie circa con habitus vario (alberi, arbusti, liane, succulente cactiformi, ed erbacee). Nella flora italiana la maggior parte delle Euphorbiaceae è erbacea.
Da un recente studio la Euphorbia peplus - Euforbia Minore sembra che possa essere usata contro i tumori cutanei. Admin aspetto le tue ricerche a tal proposito
