(6) Brunsdonna sanderw (same parentage as preceding 

 hybrid). 



The foregoing table is with five differences dupli- 

 cated by the records of this hybrid. These hybrids differ 

 more in certain particulars (both qualitatively and quan- 

 titatively) from each other than do either from their 

 parents or the parents from each other. This hybrid, like 

 its mate, bears, on the whole, a decidedly closer rela- 

 tionship to Amaryllis ielladonna than to Brunsvigia 

 josephince, and is closer than the first hybrid to Amaryllis 

 belladonna. 



The dissociation of lamellar characteristics (the form 

 and arrangement being closer to one parent, and the 

 nimiber to the other) is very interesting, but by no means 

 an uncommon phenomenon in the starches of hybrids. 

 Moreover, as will be found by reference to the context, 

 similar splitting occurs of the characters of the hilum 

 and in the size of the grains. 



That the quantitative and qualitative reactions are 

 also as independent of each other in the direction of 



their parental relationships is strikingly shown in the 

 table. Throughout the qualitative reactions the hybrids 

 incline to the seed parent, but in the quantitative reac- 

 tions wide variations are shown in the parental rela- 

 tionships. Thus, in the polarization reactions the first 

 hybrid is the same as the seed parent, while the second 

 is intermediate but closer to the seed parent; in the 

 potassium-iodide reactions both have reactivities lower, 

 than those of the parents, the first being closer to the 

 seed parent and the second as close to one as to the other 

 parent; in the sodium-salicylate reactions the first is 

 intermediate but closer to the seed parent, and the second 

 is the same as the seed parent ; and in the cobalt reactions 

 both have reactivities lower than those of the parents, but 

 one is closer to the pollen parent while the other is as 

 close to one as to the other parent. Otherwise they are 

 essentially the same in their parental relationships. 

 Curiously, while in the qualitative reactions with chloral 

 hydrate, nitric acid, potassium iodide, potassium sulpho- 

 cyanate, and sodium salicylate it is closer than the other
