Eugenia koolauensis
Also called Koʻolau Eugenia
Eugenia koolauensis, commonly known as Koʻolau eugenia or nioi, is a species of flowering plant in the myrtle family, Myrtaceae. It is endemic to Hawaii, where it could previously be found on the islands of Molokaʻi and Oʻahu; today populations only exist on the latter. This is a federally listed endangered species of the United States.
It is one of two Eugenia species native to Hawaii, and the only endemic. It is a shrub or tree that grows 2 to 7 m (6.6 to 23.0 ft) tall. The tips of the branches and the undersides of the leaves are hairy. White flowers occur in the leaf axils.
It inhabits dry gulches and ridges in coastal mesic and mixed mesic forests on the Koʻolau and Waiʻanae Ranges. Associated plant species include maile (Alyxia oliviformis), ʻahakea lau nui (Bobea elatior), Carex meyenii, uluhe (Dicranopteris linearis), kōlea lau nui (Myrsine lessertiana), olopua (Nestegis sandwicensis), hala pepe (Pleomele halapepe), ʻālaʻa (Planchonella sandwicensis), alaheʻe (Psydrax odorata), hao (Rauvolfia sandwicensis), and pūkiawe (Styphelia tameiameiae).
