as to fall into subgeneric divisions, as in the case of the 

 genera just referred to. In the Amaryllis-Brunsvigia 

 set two closely related genera are represented and there 

 is a tendency to higher reactivity of Amaryllis bella- 

 donna than of Brunsvigia josephince, differences being 

 noted especially in the numbers of the very high and the 

 low reactivities, and in the sums and averages. The hy- 

 brids show distinctly lower reactivities, as a whole, than 

 those of either parent, and there is striking identity as 

 regards the distribution of the reaction-intensities among 

 the several divisions, but there are distinct though not 

 marked differences in both sums and averages, so that 

 while these two starches are not distinguishable from 

 each other by differences in distribution of the reaction- 

 intensities they may be distinguished by the sums and 

 averages of the reaction-intensities. In the Crinums 

 there are subgeneric groups characterized by tender and 

 hardy species, the former having a tendency to distinctly 

 lower reactivities than the latter. Each of the hybrids 

 tends to be more closely related in its reaction-intensities 

 to either seed or poUen parent. 



- The differences in distribution in the highly reactive 

 species and hybrids are conspicuous especially in the high 

 number of very high reactivities and the low number of 

 the very low reactivities, and for the reverse in the low 

 reactive species and the hybrids. The sums and averages 

 are markedly different in the two groups. In Hmman- 

 thus, H. puniceus seems to be representative of a sub- 

 generic group that differs from that of which the other 

 two species belong. In Iris, the I. persica-sindjarensis- 

 persica var. purpurea set stands distinctly apart from the 

 other three, exhibiting markedly higher reactivities. In 

 Begonia, B. socotrana is evidently variant in relation 

 to the other species, and is, as is well known, an excep- 

 tional form of this genus. In Musa there is a very well- 

 marked tendency for higher reactivities of one than of 

 the other parent, which indicates that these species repre- 

 sent some form of generic subdivision.
