frequency of the parts, and found that their maxima mostly ranged them- 

 selves about 8, 13, and 21. This clearly indicated a coincidence with the 

 angular divergence of leaf arrangements — |, and /y. But as the 

 normal number of stamens is 4, the author also notes that 16 in one 

 series gave a maximum. 



Taking all his series of observations together, the following numbers 

 formed maxima : — 



4, 8, 13-14, 16, 20-21. 



So that it appears that sometimes the normal number of stamens, 4, is 

 multiplied, but in others the true spiral phyllotaxis is restored ; for, of 

 course, four stamens are merely due to the suppression of the posterior, or 

 fifth, stamen of the whorl. 



Figure 94 illustrates one of many forms of the "campanulate " flower 

 which not infrequently terminates the stem of a Foxglove. It will be seen

that there are two or more irregularly formed corolla- tubes within the 

 outermost ; two or three sets of stamens have also been formed. The 

 pistil of another flower, instead of having only two carpels, had eight,

 more familiar instance, a garden Strawberry has often several sepals 

 instead of five only. 



Tangential chorisis is a familiar feature in Roses, Camellias, and some 

 Dafi:bdils, &c., in which the petals are piled up in radial series in front 

 of one another. 



Heredity of Multifold Flowers. — We all know that the fasciated 

 form of the Cockscomb and some other plants is hereditary. If fasciation 

 were merely the accidental grafting of several bud- shoots together, or only 

 produced by accidental checking, &c., it is difficult to see how this 

 hereditary feature could be established. If, however, we look upon it as
