This plant varies in morphology, taking the form of a small shrub to a tree up to 7 meters tall.[2] There are three subspecies.[4] The dwarf subspecies, ssp. humilis, is endemic to Maui, where there is only one population consisting of about 50 plants.[4] This subspecies was federally listed as an endangered species in 1999.[5] The ssp. magnifolia is a shrub or a tree which is endemic to Kaua'i, where there are no more than 2 populations remaining. It was listed as endangered in 2010.[6]
These plants grow in moist and wet forest habitat with 75 to over 700 centimeters of precipitation annually.[2]
Threats to this species and its habitat include landslides, rockslides, erosion, flooding, and invasive plant species such as hilo grass (Paspalum conjugatum).[4] The ssp. magnifolia was decimated by Hurricane Iniki in 1992.[6]
