The six sepals cohere at their base, forming a tube and they also develop an outgrowth at the mouth of this tube, which surrounds the anthers and stigma like a cup. B, flower of Iris. C, section of same, showing in- ferior ovary, 0; stigma, g; and anther, a. large family furnishes a number of showy flowers, as the jonquil and daffodil (Narcissus), amaryllis, snowflakfe, Crinum, star grass, century plant, etc. The flowers of some genera become irregular through the unequal development of certain leaves of the perianth. The Iris family marks the culmination of the variations noted in the order. The types of flower and fruit are like those of the previous family, but the crowding on the recep- tacle has resulted in the obliteration of one whorl of stamens. The structure of the flowers often shows a series of variations that adapt them to insect visitors and crossing, as is well illustrated.
