On Hawai'i we have the closely related schiedea diffusa and schiedea hawaiiensis. These are both exceptionally rare plants which were seldom seen before recent recovery efforts began. Schiedea diffusa is known from the wet 'Ola'a forests, while a single schiedea hawaiiensis was found at arid Pohakuloa. Additionally, schiedea globosa has been found on the tiny islets off the windward Kohala coast.
