Schiedea nuttallii

About

Schiedea nuttallii is a rare species of flowering plant in the family Caryophyllaceae known by the common name valley schiedea. It is endemic to Hawaii, where it is known only from the island of Oahu. It has been extirpated from Maui and Molokai. Plants in a population known from Kauai are actually members of other species. Thus, the species is now endemic to Oahu. It is threatened by the degradation and destruction of its habitat. It is a federally listed endangered species of the United States.
