This Hawaiian lobelioid is a branching shrub which grows in wet and moist forests and gulches in the Molokai Forest Reserve.[1] The plant was not seen throughout much of the twentieth century until it was rediscovered in 1992 at the site of the single extant population. It is in decline. Threats to the species include its low numbers and limited gene pool, degradation of its habitat by axis deer, and feral pigs, damage to plants by slugs, rats, and birds, and competition by exotic plants such as climbing dayflower (Commelina diffusa), air plant (Kalanchoe pinnata), and castor bean (Ricinus communis).[2]

Propagation efforts in the greenhouse have met with little success.[2]
