Flowers are borne on singular pedicels arising from between the leaves with many capable of being produced at once, up to 1.5 cm across with ovular to nearly rectangular petals bearing serrated edges. Color is mauve to violet on the upper surface, white to yellowish on the lower surface. Sepals are densely covered in glands, This species is distinct from others in the genus in possessing anthers as long as or longer than the filaments in the flowers and a mostly erect to slightly scrambling stem, as well as a lack of sessile glands on pedicels and sepal bases.
