Hibiscadelphus crucibracteatus (lava hau kuahiwi)[3] is an extinct species of flowering plant in the family Malvaceae that was endemic to Hawaii, on the island of Lanai.

It was discovered in 1981 on the Puhielelu Ridge and the single known specimen has since died, with collected seeds failing to germinate.[1]
