Vittadinia consanguinea A. Gray , Proc. Amer. Acad. Arts 5: 120. 1861.
Type information:
Lectotype [US]. U. S. Expl. Exped. s.n.. 1840. Kaua`i: mountains.
Lectotypified in Sherff. Bernice P. Bishop Mus. Bull. 135: 19. 1935.

Note: Additional syntype: Hawai`i, Waimea, U. S. Expl. Exped. s.n. (GH, NY). Lowrey considered the US sheet the holotype, but since Gray cited collections from both Hawai`i and Kaua`i, they are all syntypes and Sherff's treatment is taken as a lectotypification.
