The order^sculinea^ is of special interest in this connection, since in some of its families(Acerineae and Hippocastanese, Fig. 424) the interposed staminal whorl remainsincomplete, so that the total number of stamens is not a multiple of the typicalfundamental number (five). Among pentamerous flowers Lythrarieae, Crassulacese,and Papilionaceae may be mentioned in addition, and among tetramerous onesQ^nothereae, in which a complete staminal whorl is interposed. One of the most remarkable deviations from the ordinary structure takes theform in not a few families of Dicotyledons of the simple staminal whorl being.
