Maryland SennaIndividual flowers are about ¾" across, consisting of 5 spreading yellow petals, 5 spreading greenish yellow sepals, 10 stamens with dark brown anthers, and a pistil with a style that curls upward at its tip. The stamens are organized into three groups: the lower 3 stamens have long filaments and long anthers, the middle 4 stamens have short filaments and long anthers, while the upper 3 stamens have short filaments and short anthers. Of these, the lower and middle stamens are fertile, while the upper stamens are sterile. The slender green styles are covered with short appressed hairs.
Shortly afterwards, the flowers are replaced by drooping seedpods. These seedpods are narrowly oblong in shape and flattened with single-seeded segments.
