Strother's (2006) statement that "reports of Acanthospermum xanthioides (Kunth) de Candolle from New York are evidently based on specimens of A. australe" could be taken to mean that these two names refer to distinct taxa but both Blake (1921) and J. Strother (personal communication) consider Acanthospermum xanthioides and A. australe to be conspecific. In fact, J. Strother (personal communication) had meant to include A. xanthioides as a synonym of A. australe in his FNA treatment (Strother 2006) but the text was apparently omitted. It has been restored in the on line version of FNA.
