The upper two tongue-shaped petals are bent to the side and have wine-red feather-like markings. The lower three spatulate petals are drawn pale pink at the base. Of the five fertile stamens , an upper and two lateral ones are very short and hidden in the sheath-like petal bases. Two additional, lateral stamens are bent back. The pollen is orange and the stigma is dark pink in color.
