|The Atoll Chaff Flower was
an 1 to 2 m tall shrub that was distributed on the northwestern atolls of
the Hawaiian island chain, where the species could be found on the Kure
atoll, the island of Laysan, the Midway atoll as well as the Pearl and
Hermes Reef atoll.
On the island of Laysan the whole vegetation was destroyed by Guinea Pigs (Cavia porcellus (L.)) and Rabbits (Oryctolagus cuniculus (L.)), that were both intentionally introduced at the beginning of the 20. century. On the others of the abovementioned islands the species obviously disappeared as a result of human interventions, like the building of military bases.
The Atoll Chaff Flower was last seen in the year 1964 on the Kure atoll, and is considered extinct since.
