Achyranthes atollensis

Description

Achyranthes atollensis (also called atoll achyranthes or Hawaiʻi chaff flower) was a species of plant in the Amaranthaceae family. It was endemic to the Northwestern Hawaiian Islands of Kure, Midway, Laysan and the Pearl and Hermes Atoll. Its natural habitat was sandy shores. It became extinct due to habitat loss (residential, commercial and military installation development) and the introduction of non-native species, and was last seen in 1964. It was a perennial shrub living in dry shrublands on calcareous sand and atolls.
