Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of the type genus of 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 has a cosmopolitan global distribution. The greatest diversity of species is in the tropics; however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica.
Euphorbia ingens is a species of flowering plant in the family Euphorbiaceae. It is native to dry areas of southern Africa. It is popularly known as the candelabra tree or naboom. Its milky latex can be extremely poisonous and is a dangerous irritant.

The Huntington Desert Garden is part of The Huntington Library, Art Collections and Botanical Gardens in San Marino, California. The Desert Garden is one of the world's largest and oldest collections of cacti, succulents and other desert plants, collected from throughout the world. It contains plants from extreme environments, many of which were acquired by Henry E. Huntington and William Hertrich in trips taken to several countries in North, Central and South America. One of the Huntington's most botanically important gardens, the Desert Garden brought together a group of plants largely unknown and unappreciated in the beginning of the 1900s. Containing a broad category of xerophytes, the Desert Garden grew to preeminence and remains today among the world's finest, with more than 5,000 species in the 10 acre garden.

Rubber production in Sri Lanka commenced in 1876, with the planting of 1,919 rubber seedlings at the Henarathgoda Botanical Gardens in Gampaha. The total extent under rubber in 1890 was around 50 ha and in the early 1900s it increased to around 10,000 ha. By 1982 the total extent under rubber was around 180,000 ha and the total annual production was 125,000,000 kg (276,000,000 lb). However, the total extent under rubber declined subsequently and at present it is around 120,000 h (430,000 ks)a. Rubber contributes about 0.6% of the total GDP. According to figures published in 2018 by the Rubber Research Institute of Sri Lanka, producing 82,600,000 kg (182,100,000 lb) in 2018.
