Euphorbia exigua, dwarf spurge or small spurge, is a species of Euphorbia in the spurge family (Euphorbiaceae), native to Europe, northern Africa and the Near East, and invasive worldwide.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the spurge family (Euphorbiaceae). "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae, not just to members of the genus. Some euphorbias are commercially widely available, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant. Euphorbias from the deserts of Southern Africa and Madagascar have evolved physical characteristics and forms similar to cacti of North and South America, so they are often incorrectly referred to as cacti. Some are used as ornamentals in landscaping, because of beautiful or striking overall forms, and drought and heat tolerance.
Euphorbia esula, commonly known as green spurge or leafy spurge, is a species of spurge native to central and southern Europe, and eastward through most of Asia north of the Himalaya to Korea and eastern Siberia.
Aphthona is a genus of beetle, in the leaf beetle family Chrysomelidae, native to Europe and Asia. More specifically, Aphthona are flea beetles, meaning they have enlarged hind legs for jumping away from potential danger. There are some 300 species known worldwide.
Euphorbia heterophylla, also known under the common names of (Mexican) fireplant, painted euphorbia, Japanese poinsettia, desert poinsettia, wild poinsettia, fire on the mountain, paintedleaf, painted spurge, milkweed, and kaliko plant, is a plant belonging to the Euphorbiaceae or spurge family.
Euphorbia myrsinites, the myrtle spurge, blue spurge, or broad-leaved glaucous-spurge, is a succulent species of flowering plant in the spurge family Euphorbiaceae.
Euphorbia resinifera, the resin spurge, is a species of spurge native to Morocco, where it occurs on the slopes of the Atlas Mountains. The dried latex of the plant was used in ancient medicine. It contains resiniferatoxin, a capsaicin analog tested as an analgesic since 1997.
Euphorbia lathyris, the caper spurge or paper spurge, is a species of spurge native to southern Europe, northwest Africa, and eastward through southwest Asia to western China.
Euphorbia lactea is a species of spurge native to tropical Asia, mainly in India.
Euphorbia maculata, known as spotted spurge or prostrate spurge, the latter name not to be confused with Euphorbia prostrata, is a fast-growing annual plant in the family Euphorbiaceae, native to North America. It is a common garden and lawn weed in the United States.
Aphthona abdominalis is a species of leaf beetle known as the minute spurge flea beetle. It was used as an agent of biological pest control against the noxious weed leafy spurge, but never established a viable population.
Euphorbia corollata is an herbaceous perennial plant in the family Euphorbiaceae that is native to North America. A common name for the species is flowering spurge. It has a milky sap that can cause skin and eye irritation in some people. It grows up to 1 m (3 ft) tall, with smooth stems and light green leaves arranged alternately or in whorls. Leaves are about 10 mm wide and 75 mm (3 in) long. Each stem terminates in a panicle 20 to 25 mm across. Flowers are about 6 mm across and consist of one pistillate and several staminate flowers surrounded by five white bracts - not petals but formed from the involucre at the base of the flowers. Flowering spurge blooms from June to September.
Euphorbia spathulata is a species of spurge known by the common names warty spurge and roughpod spurge.
Euphorbia poissonii, also known as Euphorbia poissoni and, incorrectly as Euphorbia poisoni is a highly irritant and toxic succulent member of the large and varied spurge family of plants. It is native to northern Nigeria, where local farmers extract its latex for use as a pesticide. Its powerfully irritant and pain-producing nature mandates use as a fencing plant. It is known to the Berom people of the Jos area as pyùlúp who transplant it to their compounds where it is regarded as protection against witchcraft.
The Euphorbiaceae, the spurge family, are a large family of flowering plants. In common English, they are sometimes called euphorbias, which is also the name of a genus in the family. Most spurges such as Euphorbia paralias are herbs, but some, especially in the tropics, are shrubs or trees, such as Hevea brasiliensis. Some, such as Euphorbia canariensis, are succulent and resemble cacti because of convergent evolution. This family occurs mainly in the tropics, with the majority of the species in the Indo-Malayan region and tropical America a strong second. A large variety occurs in tropical Africa, but they are not as abundant or varied as in the two other tropical regions. However, the Euphorbiaceae also have many species in nontropical areas such as the Mediterranean Basin, the Middle East, South Africa, and the Southern United States.
Euphorbia marginata is a small annual in the spurge family.
Aphthona nigriscutis is a root-feeding flea beetle of the genus Aphthona. It is one of 5 Aphthona spp. that has been used in Alberta, Canada to control leafy spurge, an invasive plant that reduces pasture quality and degrades natural habitats. It, along with A. lacertosa, is one of only two biocontrol agents thought to be effective against leafy spurge.
Euphorbia virgata, commonly known as leafy spurge, wolf's milk leafy spurge, or wolf's milk is a species of spurge native to Europe and Asia, and introduced in North America, where it is an invasive species.
Euphorbia hypericifolia is a species of perennial herb in the genus Euphorbia native to tropical Americas. It can grow up to 2 feet (0.6 m) in height, and contains milky sap which can cause skin and eye irritation.
Euphorbia brachycera is a species of flowering plant in the Euphorbiaceae family. It is referred to by the common name horned spurge and is native to Northern Mexico and the Rocky Mountains of the US. It is a rhizomatous herbaceous perennial growing in spreading mats, with narrow green leaves and yellow flowerheads.
