Hibiscadelphus wilderianus

Hibiscadelphus wilderianus, also known as the Maui hau kuahiwi is an extinct species of flowering plant in the family Malvaceae that was endemic to Hawaii.

Extinction
The plant was endemic to ancient lava fields on the southern slopes of Mount Haleakalā, on Maui, Hawaii. Its forest habitat was devastated by cattle ranchers, and the final tree was found dying in 1912. Today it is believed to be extinct.

In 2019 the scent of the flower was recreated using DNA sequenced from a preserved specimen.
