Melicope adscendens

This is a shrub with long, slender branching stems and inflorescences of 1 to 3 flowers. It grows in degraded forest habitat on the slopes of the volcano Haleakalā.[1] There is a single plant on state-owned property, and perhaps 25 more on private property.[4] The solitary plant on state land is protected in an enclosure in the Kanaio Natural Area Reserve, and it is producing fruit. None of the other plants have been observed reproducing.[4]

This plant is threatened by the loss and degradation of its habitat. The slopes of the volcano are used as pastures for grazing cattle, and various types of feral ungulates are present, such as feral pigs, Axis deer, and feral goats. Many species of non-native plants are present in the area, including balloon plant (Asclepias physocarpa), beggarticks (Bidens pilosa), lantana (Lantana camara), prickly pear (Opuntia ficus-indica), and kikuyu grass (Pennisetum clandestinum).[4]
