Vittadinia arenaria A. Gray , Proc. Amer. Acad. Arts 5: 120. 1861.
Type information:
Lectotype [US]. U. S. Expl. Exped. s.n.. 1840. Maui: on sand hills.
Lectotypified in Sherff. Bernice P. Bishop Mus. Bull. 135: 20. 1935. Isolectotype(s) [GH].

Note: Lowery's lectotypification (Allertonia 4:257. 1986) on a specimen from Hawai`i is superfluous. (In US type register under Tetramolopium, but could not find specimens in US type collection or general collection 6/98, RKS).
