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.
