It is known as hau kuahiwi in Hawaiian, which means "upland Hibiscus tiliaceus." It is a bush or small tree with heart-shaped leaves and yellow flowers and grows at between 1,000 and 1,800 feet in the remnants of native dry forests.

A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
Gardenia brighamii, commonly known as nānū, naʻu, or forest gardenia, is a species of flowering plant in the coffee family, Rubiaceae, that is endemic to Hawaii.

Cylindrocline lorencei is a small tree that was native to the island of Mauritius, with only one specimen ever observed in the wild. By 1990 the species was considered extinct, and the only available seed could not be germinated. Brest Botanic Gardens successfully performed in vitro culture of a viable part of the seed embryo, saving the plant from extinction. Through further vegetative propagation at Brest and Kew Botanic Gardens, a small population of Cylindrocline lorencei has been grown and efforts are now underway to re-establish it in its native habitat.
Tulipa sprengeri, or Sprenger's tulip, is a wild tulip from the Pontic coast of Turkey. It is quite rare and possibly extinct in the wild, but widely cultivated as an ornamental.
