The plants formerly referred to as Minuartia alabamensis have been shown to be a self-pollinating form of Geocarpon uniflorum that has arisen independently at various locations, and it is thus included under this species. Genetic evidence suggested that this species is best placed in the genus Mononeuria, although that classification was not been widely adopted.[3] In 2022 it was placed in genus Geocarpon.[1]

This species is distinguished from the similar Geocarpon glabrum by having shorter leaves and petals that are not clawed.
