Euphorbia skottsbergii

Euphorbia skottsbergii (syn. Chamaesyce skottsbergii) is a rare species of flowering plant in the euphorb family known by the common names coastal sandmat and Skottsberg's broomspurge. It is endemic to Hawaii, where it is found in coastal shrublands on Oʻahu, Molokaʻi, Maui, and Kahoʻolawe. Like other Hawaiian euphorbs, this plant is known locally as ʻakoko. The taxonomy of this plant is still being studied; the name and number of varieties have changed over the years and are still in flux. In 1982 the rare variety kalaeloana was added to the endangered species list of the United States. This plant was and still is known only from Oʻahu's ʻEwa Plains between Kalaeloa (Barber's Point) and Pearl Harbor. It had been reduced in population by a number of factors, including Navy activity, pollution, destruction by bulldozer on private property, quarrying, agriculture, fire, development and construction of housing, roads, an oil refinery, and resort property, and expansion of the harbor.
