Associates: Metsideros polymorpha var. glaberrima, Pleomele sandwicensis, Diiospyros hillebrandii, Diospyros sandwicensis, Antidesma platyphylla, Pouteria sandwicensis, Rauvolfia sandwicensis, Santalum freycinetianum var. pyrularium, Psychotria mariniana, Chamaesyce celastroides var. hanapepensis, Wilkesia gymnoxiphium, Pritchardia napaliensis, Bidens sandvicensis subsp. sandvicensis, Lipochaeta connata var. acris, Nesoluma polynesicum, Pteralyxia kauaiensis, Psydrax odoratum, Boehmeria grandis, Musa x paradisiaca, and Zanthoxylum dipetalum.
Major Threats: habitat degradation by goats, competition with non-native plant taxa such as Lantana camara, Erigeron karvinskianus, Rubus rosifolius, Kalanchoe pinnata, Psidium guajava, and Andropogon glomeratus, and the loss of reproductive vigor as the result of limited numbers of existing individuals.
