There are three anticous fertile stamens, meaning they are on the lower part of the flower, and three posticous infertile stamens, meaning they are on the upper part of the flower. These infertile stamens are termed staminodes. The fertile stamens are dimorphic: the lateral pair have maroon to indigo anthers that measure about long and are elliptic with a base that is or arrowhead-shaped. Their filaments are about long. The central fertile stamen has a yellow, elliptic anther with a maroon connective and a base that is or spearhead-shaped, but with the lobes at right angles. The anther measures about long while its filament is about long. The three staminodes are all alike with yellow, cruciform, or cross-shaped, antherodes that are about long on filaments about long. Sometimes the antherodes will have a central maroon spot. Each antherode has two abortive lateral pollen sacks. The ovary is , about long and has a style that is about long.
