(b) Brunsdonna sanderos (same parentage as preceding 

 hybrid i. 



ing table is with five differences dupli- 

 lords of this hybrid. These hybrids differ 

 more in certain particulars (both qualitatively and quan- 

 titatively) from each other than do either from bheir 

 parenl parents from each other. This hybrid, like 



its mate, bears, on the whole, a d» idedly closer rela- 

 tionship t" Amaryllis belladonna than to Brunsvigia 

 and is closer than the lirst hybrid to Amaryllis 

 belladonna. 



The dissocial i< n of lamellar characteristics (the form 

 anil arran ; closer to one parent, and the 



number t r) is very interesting, but by no means 



an uncommon phenomenon in the starches of hybrids. 

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

 similar splitting occurs of the characters of the hilum 

 and in the si grains. 



That the quantitative and qualitative reactions arc 

 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, hut in the quantitative reai - 

 tions wide variations are shown in the parental rela- 

 tionships. Thus, in the polarization reactions the lirst 

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

 is intermediate hut 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 parenl am] the second as close to one as to the other 

 parent; in the sodium-salicylate reactions the lirst is 

 intermediate hut closer t" the seed parent, and the second 

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

 both have read i\ ities 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- 

 ite, and sodium salicylate it is closer than the other
