leaf Special Features and Information

General Information

This is an endangered species belonging to the Amaranth family (Amaranthaceae). Other native Hawaiian family members include two other species in the same genus with one very likely extinct; a rare and little known amaranth (Amaranthus brownii) from Nīhoa (Moku Manu); ʻāweoweo (Chenopodium oahuense); and several species of pāpala (Charpentiera spp.) and kuluʻī (Nototrichium spp.).

The variety differences in Achyranthes splendens is based on flower and leaf variation.

The name ʻEwa hinahina or Hinahina ʻewa has an unknown modern origin.

Early Hawaiian Use

Though there is no known Hawaiian name or use for this plant, as a lowland species it certainly would not have gone unnoticed by early settlers.
