The flowers of Impatiens are difficult to interpret. There are 3 sepals—a lower one that is petaloid and forms a conical structure prolonged backward into a slender nectary spur and 2 upper ones that are small and sepaloid or petaloid. There are 5 petals—an upper one that is concave and projected upward or forward and 2 lower ones that are each formed from 2 connate petals.
