It is a perennial herb producing an erect flowering stem from a patch of basal leaves. The leaf has a rounded blade at the end of a long petiole, the leaf reaching a total of up to 16 centimeters long.

The single flower has five small jagged sepals behind five veined, fringed white petals each roughly a centimeter long. At the center of the flower are five stamens and five staminodes with edges of many narrow, round-tipped lobes.
