Until the first decade of the twenty-first century, the five genera of Huerteales had usually been placed into three unrelated families. "Tapiscia" and "Huertea" had long been known to be related. Most authors had placed them in Staphyleaceae and had placed that family in the order Sapindales. Armen Takhtajan established the family Tapisciaceae in 1987 and placed it in Sapindales, but this treatment was not followed by many others and it did not stand up to phylogenetic analysis. Since that time, Staphyleaceae has been recircumscribed. It no longer includes "Tapiscia" and "Huertea" and it is in the order Crossosomatales.
