The inflorescence is an open array of several clusters of small flowers, each flower accompanied by a single wide bract sometimes larger than the flower itself. The five yellow petals of the flower are under half a centimeter long. The fruit is a narrow cylindrical utricle containing several tiny, pyramidal seeds.
