  • used in childbirth

HAWAIIAN RAIN FOREST ECOLOGY

  • locally found in relatively undisturbed rain forest
  • abundant in park’s `Ola`a Forest
  • at Niaulani, `akolea shorter than kahili ginger so may have been displaced by this weed
  • understory fern of the forest floor, usually growing from soil but also on nurse logs
  • largest individuals in Niaulani adjacent to the nature trail, probably where planted
  • smaller individuals near the trail and nearby areas, indicating that this fern is regenerating and spreading, now that pigs and ginger controlled
