Discussion
Of conservation concern.
According to D. F. Austin (1984), Harrisia aboriginum and H. simpsonii are weakly separated, differing primarily in fruit color, which remains yellow in H. aboriginum while turns to red at maturity in H. simpsonii.
Harrisia aboriginum has been found on pre-Columbian, aboriginal shell mounds, hence the specific epithet.
