État de la populationTexte officiel évaluation IUCNExpert
The taxon is rare, with a maximum estimated population of 250 mature individuals. Two subpopulations are known, but more surveys are needed. There is no detailed long-term monitoring record, but few juveniles have ever been observed in any of the known sites and so the population is in decline.

Description complète des menacesTexte détaillé évaluation IUCNExpert
The major threats to this taxon include direct competition by invasive non-native plant species, as well as predation and habitat degradation by non-native animals. Particularly feral pigs (Sus domesticus), which degrade the habitat and harm the plants through predation, trampling, and rooting for food. Rats (Rattus rattus) pose a threat to the species through predation of its plant parts and fruits. Alien plants also threaten the species by altering its habitat and competing with it for moisture, nutrients, light, and space.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
The taxon is not on the U.S. Endangered Species List or State of Hawaiʻi Endangered Species List, but does occur in areas managed for watershed protection. More research is needed to provide guidance on optimal conservation strategies and threat abatement and on general ecology, life history, population size, distribution, and trends.
