Euphorbia fruticosa is native to Yemen. It is a member of the order Malpighiales and the family Euphorbiaceae.
Plants of the genus Euphorbia belong to the order Malpighiales, family Euphorbiaceae. They are commonly referred to as spurges.
Euphorbia millii, of the order Malphighiales and family Euphorbiaceae, is native to Madagascar.
Species of the Euphorbiaceae are highly specialized, with flowers having between 2-6 sepals and 0-5 petals and as little as one anther or stamen. The family is widely dispersed, but centers on the tropics of the Americas and Africa. Many species produce a potentially poisonous milky sap. Saps of these plants have been used variously for arrow poison, fish kills, medicines, and production of rubber, tung oil, hydrocarbons, cassava and tapioca. A number of species in this family have forms similar to cacti (in the family Caryophyllales), which is an example of convergent evolution.
Euphorbia pseudocactus is native to South Africa. It is a member of the order Malpighiales and the family Euphorbiaceae.
Euphorbia pulcherrima is a member of the order Malpighiales, family Euphorbiaceae. It is native to Mexico and Central America and is known for its bright red "flowers," which are actually bracts (modified leaves), surrounding much smaller yellow flower clusters.
Euphorbia tirucalli is native to Africa and is a member of the order Malpighiales, family Euphorbiaceae. It grows readily even in difficult environments and produces a milky latex that is toxic and causes skin irritation.
Jatropha podagrica is a member of the order Malpighiales, family Euphorbiaceae. It is native to the Americas and is toxic due to the presence of curcin.
Hypericum perforatum is a member of the order Malpighiales, family Hypericaceae. It is native to temperate regions of Europe. Preparations of this plant are sold as a treatment for depression.
Averrhoa carambola is a member of the order Oxalidales, family Oxalidaceae. It is native to Southeast Asia and India and produces a yellow star-shaped fruit. This specimen was grown from the seed of a grocery-store purchased fruit.
Biophytum sensitivum is a member of the order Oxalidales, family Oxalidaceae. Preliminary research suggests that it contains compounds with various medicinal relevance, including potential anti-microbial and anti-inflammatory effects.
Oxalis acetosella is a member of the order Oxales, family Oxalidaceae. It is native to parts of Europe and Asia.
Members of the family Oxalidaceae are characterized by their flowers of 5 petals and 5 sepals, with stamens in two sets of 5. The name of the family derives from the Greek word for acid, and the name for oxalic acid derives from plants of this family, some of which are used for commercial extraction of potassium oxalate. In Oxialidaceae species native to shady forests, the leaves move downward in response to specific light conditions.
