"Hibiscadelphus crucibracteatus is one of seven Hibiscadelphus trees native to Hawaii. All are endangered, extinct in the wild, or extinct. H. crucibracteatus is known only from the type specimen, a single tree discovered in 1981 on a windward, dry slope of Puhielelu Ridge, Lanai. Seeds were harvested on several occasions, but none germinated."
