Ischaemum byrone (Trin.) Hitchc.. Ischaemum byrone, commonly known as Hilo murainagrass or Hilo ischaemum, is a species of grass native to the Pacific Islands, including the Cook Islands, Fiji, Hawaiian Islands, New Caledonia, Niue, Society Islands, Tonga, Tubuai Islands, and Wallis and Futuna. In Hawaii it is found on the islands of Kauai, Maui, Molokai, and Hawaii but has unfortunately been extirpated from Oahu, where it was once known to grow.
