Notes

  • Description digitized by Dylan Charter
  • Description digitized from the Manual of the Flowering Plants of Hawaii
  • First recorded by Rock (1920a'), but since then no recent collections have been made and perhaps this species no longer persists in Hawai'i.
  • The Hawaiian collections are referred to var. strigosum, characterized by the rachis of the inflorescence densely pubescent with appressed, straight, nonhooked hairs. In contrast, var. heterocarpon is characterized by the inflorescence rachis densely pubescent with spreading hooked hairs.
