Шаблон:Short description Шаблон:Speciesbox
Euphorbia deppeana is a rare species of flowering plant in the family Euphorbiaceae[1] known by the common names Deppe's broomspurge and Oahu sandmat. It is endemic to [[Oahu|OШаблон:Okinaahu]], Hawaii, where it is known from only one population[2] in moist shrublands on [[Nu‘uanu Pali|NuШаблон:Okinauanu Pali]].[3] Like other native Hawaiian euphorbs it is called Шаблон:Okinaakoko locally.
This shrub is erect or sprawling in form. The stems may exceed a meter in length and contain milky sap.[3]
The plant has never been abundant as long as the area has been surveyed for flora.[2] It was not seen for many decades and by the 1980s it was feared extinct.[2] The single known population was rediscovered in 1986 and it contained fewer than 100 plants.[2] In 1994 it was added to the United States' endangered species list.[2] By 2007 the population was estimated to have exceeded 100 plants, but they are hard to count because they grow on a sheer rock cliff in the middle of a tourist area.[2]
The species is still considered endangered because there is only a single population and it is threatened by a number of processes.[2] Several invasive plant species have moved into the area and compete with the rare native for water, light, nutrients, and physical space.[2] The most important non-native plants in the area include ironwood (Casuarina equisetifolia), Hilo grass (Paspalum conjugatum), Christmasberry (Schinus terebinthifolius), and the common guava (Psidium guajava).[4][2] Other threats to the species include fires and human interference with the plants.[4][3]
