Kokiʻo keʻokeʻo (Hibiscus waimeae) has two subspecies. The subspecies hannerae is federally listed as an endangered species. It is distinguished by the much larger leaves and smaller flowers than appear in subspecies waimeae.
The generic name Hibiscus is derived from hibiscos, the Greek name for mallow.
The specific epithet waimeae refers to the Waimea Canyon, Kauaʻi, where this species is found.
The subspecies hannerae was named by the botanist couple Otto and Isa Degener in honor of Mrs. Ruth Knudsen Hanner, a supporter of their work on Kauaʻi. 
Aloalo is the name given for hibiscus in general.
Hau is an introduced hibiscus (Hibiscus tiliaceus), perhaps by early Hawaiians. Hau hele literally means "traveling hau."
Kokiʻo kea and Kokiʻo keʻokeʻo literally mean "white kokiʻo" and "white, white [clear white] kokiʻo," respectively.
The two native Hawaiian white hibiscuses, Hibiscus arnottianus and H. waimeae, are the only species of hibiscuses in the world known to have fragrant flowers!
