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 (), , uluhe (Dicranopteris linearis), kōlea lau nui (Myrsine lessertiana), olopua (Nestegis sandwicensis), hala pepe (Pleomele halapepe), ʻālaʻa (Pouteria 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]
