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.
This is one of two Eugenia species native to Hawaii, and the only endemic. [3] It is a shrub or tree grows 2 to 7 meters tall. The tips of the branches and the undersides of the leaves are hairy. White flowers occur in the leaf axils [4]
Habitat
It inhabits dry gulches and ridges in coastal mesic and mixed mesic forests on the Koʻolau and Waiʻanae Ranges. [3] 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). [4]
It is threatened by habitat loss and recently Puccinia psidii, a non-native fungal disease. [3]
In 2008 there were fewer than 300 mature plants in the Koʻolau Range and only three in the Waiʻanae Range. [3] It is extirpated from the island of Molokaʻi, where its former habitat was cleared for pineapple fields. [1]
