The inflorescence may be nearly half a meter tall and consists of a mostly naked peduncle with one bract midway up.

The single flower has five small sepals behind five veined white petals each 1 to 2 centimeters long. At the center of the flower are five stamens and five staminodes with fringes of many hairlike, sphere-tipped lobes.
