Discussion

Varieties 3 (all in the flora).

Hexastylis arifolia is the most widespread species in the genus. Along the boundaries where the ranges of the varieties meet, intermediate specimens are occasionally found.

The Catawba tribe used Hexastylis arifolia (no varieties specified) medicinally for stomach pains, miscellaneous pains, heart trouble, and backaches; the Rappahannock, for treating whooping cough and asthma (D. E. Moerman 1986).
