Platanthera holochila is a rare species of orchid known by the common name Hawaii bog orchid. It is endemic to Hawaii. It is a federally listed endangered species of the United States. When the orchid was added to the Endangered Species List in 1996 there were fewer than 35 individuals remaining, divided amongst small populations located on the islands of Kauai, Maui, and Molokai. It has been extirpated from Oahu. By 2009 there were three populations for a total of 26 plants. There is only one plant remaining on Kauai and one on Maui, but neither have been observed recently. Hurricane Iniki destroyed most of the Kauai population in 1992. The largest population, located on Molokai, is surrounded by a fence for protection from feral pigs, a main threat to the survival of the species. Other t
