Euphorbia deppeana is a rare species of flowering plant in the family Euphorbiaceae[2] known by the common names Deppe's broomspurge and Oahu sandmat. It is endemic to Oʻahu, Hawaii, where it is known from only one population[3] in moist shrublands on Nuʻuanu Pali.[4] Like other native Hawaiian euphorbs it is called ʻakoko locally.
This shrub is erect or sprawling in form. The stems may exceed a meter in length and contain milky sap.[4]
The plant has never been abundant as long as the area has been surveyed for flora.[3] It was not seen for many decades and by the 1980s it was feared extinct.[3] The single known population was rediscovered in 1986 and it contained fewer than 100 plants.[3] In 1994 it was added to the United States' endangered species list.[3] 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.[3]
The species is still considered endangered because there is only a single population and it is threatened by a number of processes.[3] Several invasive plant species have moved into the area and compete with the rare native for water, light, nutrients, and physical space.[3] 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).[1][3] Other threats to the species include fires and human interference with the plants.[1][4]

Euphorbia deppeana, es una especie fanerógama perteneciente a la familia Euphorbiaceae. Es originaria de las islas Hawái.
Euphorbia deppeana es endémica de la isla de Oahu, Hawáii. Se conoce a partir de sólo una población, por un total de menos de 50 individuos. Las plantas están amenazadas por la competencia con las plantas exóticas. El impacto humano puede también representar una amenaza, ya que las plantas están cerca de un mirador visitado con frecuencia. Varias especies de plantas invasoras se han trasladado a la zona y compiten con las raras especies nativas por agua, luz, nutrientes, y espacio físico.[2] Las más importantes plantas no nativas de la zona incluyen a Casuarina equisetifolia, Paspalum conjugatum, Schinus terebinthifolius y la guayaba común Psidium guajava.[1][2] Otras amenazas para la especie son los incendios y la interferencia humana en las plantas.[1][3]
Euphorbia deppeana fue descrita por Pierre Edmond Boissier y publicado en Centuria Euphorbiarum 6. 1860.[4]
Euphorbia: nombre genérico que deriva del médico griego del rey Juba II de Mauritania (52 a 50 a. C. - 23), Euphorbus, en su honor – o en alusión a su gran vientre – ya que usaba médicamente Euphorbia resinifera. En 1753 Carlos Linneo asignó el nombre a todo el género.[5]
deppeana: epíteto otorgado en honor del botánico y viajero alemán; Ferdinand Deppe (1794 -1861).[6]
