Silene hawaiiensis
Hawai'i catchfly is a rare, native subshrub endemic to the island of Hawai'i, growing on lava and ash slopes of its volcanoes. It is a threatened, federally protected species, so it is grown mainly by conservation and native-plant collections rather than as a garden plant.
Silene hawaiiensis is a rare species of flowering plant in the family Caryophyllaceae known by the common names Hawai'i catchfly, Hawaiian catchfly and Sherff's catchfly. It is endemic to Hawaii, where it is known only from the island of Hawaii. It is threatened by habitat degradation and is federally listed as a threatened species in the United States.
This plant grows on the lava and ash substrates of the volcanoes of the island of Hawaii. It grows at Kīlauea, Mauna Loa, Mauna Kea, and Hualālai. It is a member of the sparse flora in the southwest rift zone of Kilauea, which includes such plants as Coprosma ernodeoides (pilo), Dubautia ciliolata (naenae), Leptecophylla tameiameiae (pukiawe), Metrosideros polymorpha (ʻōhiʻa lehua), Nephrolepis exaltata (nianiau, ikupukupu), Sadleria sp. (amau), and Vaccinium reticulatum (ōhelo ʻai). A recent estimate is a total of 22 populations containing 8360 individuals.
