Hesperomannia arbuscula Hillebr.

Hesperomannia arbuscula Hillebr.. Hesperomannia arbuscula, the Maui island-aster or Maui hesperomannia, is a species of flowering plant in the family Asteraceae that is endemic to the island of Maui in Hawaiʻi; plants from Oʻahu are now classified as Hesperomannia oahuensis. It is found in mixed mesic and wet forests at elevations of 350–900 m (1,150–2,950 ft). It is threatened by habitat degradation caused by feral pigs, competition with alien plants, predation from rats, and trampling or collecting by humans.
