Oak-leaved Cyanea (Cyanea quercifolia)  

The Oak-leaved Cyanea was described in 1888 as a variety of another species, the Solanum-like Cyanea (Cyanea solanacea Hillebr.).  

The species is apparently known only from the type collection that was obtained in 1870 [?] somewhere between 915 m and 1220 m on the western slopes of Haleakala volcano in the eastern part of Maui, Hawaiian Islands.
