The terminal inflorescence has rich yellow flowers. Each of these has five small, broad, blunt sepals with black dots on the margins. The five petals are red beneath and have red and black dots on the margins. There are three styles and many stamens with orange anthers in three bundles. The fruit is a dehiscent capsule.[1][2]
