Discussion:Acacia schaffneri (S. Wats.) F. J. Hermann pro parte Poponax schaffneri (S. Wats.) Britt. & Rose pro parte A. tortuosa auct. CN 2n = 26 (Turner & Fearing, 1960a; as A. tortuosa). Most herbarium specimens of Acacia schaffneri var. bravoensis and A. smallii (A. farnesiana auct.) lack fruit and are frequently confused. They may be distinguished by the leaflet reticulation of var. bravoensis, the location of leafstalk glands, and the nature (especially length) of the flowering peduncles. Correll and Johnston (1970) report presumed hybridization between A. tortuosa and hiusache (A. schaffneri and A. smallii).
