hybrid to Amaryllis belladonna, in the copper-nitrat 

 cupric-chloride reactions it is not bo close as the other 

 hybrid. 



Hippeastrtjm. (Table C 2.) 



In comparing these records and keeping in view the 

 botanical closeness of the parents in each case, and also 



a corresponding closeness of tl ffspring to tlie parent-, 



together with the great importance that is commonly 

 attached to intermediateness as a criterion of hybrids, 

 one is struck by (1) the frequency of the development 

 of properties of the hybrid in excess or deficit of parental 

 extremes; ('-') the appearance of reactions in t he hybrid 

 which were not seen in the parent- ; and (.'!) the swinging 

 of hybrid development to one or the other parent in an 

 utterly inexplicable manner. Among the 36 designal ions 

 of the three sets, in no less than 23 some property or 

 properties were developed in excess of parental extremes, 

 and in t there was deficienl development. Tn two in- 

 stances properties -were noted in the hybrid that were 

 not apparent in either parent. The hybrid of the first 

 set is in form closer to the seed parent, hut in the second 

 and third sets it is closer to the pollen parent ; in hilum, 

 in the first and third sets, closer to the seed parent, hut 

 in the second set closer to the pollen parent ; in lamella?, 

 in the first set closer to the pollen parent, in the third 

 set closer to the seed parent, and in the second set closer 

 to the seed parent in number and to the pollen parent in 

 general characters; in size, in the first set closer to the 

 pollen parent, in the second set closer to the seed parent, 

 and in the third set equally like both parents in common 

 size, but like the pollen parent in the larger grains.

 The quantitative and qualitative reactions show com- 

 paratively the most variable relation-hips.

 The hybrid in the first set, in form and hilum 

 closer to tlie seed parent; in lamella' it resembles both 

 parents in equal degree; and in size it is nearer the 

 pollen parent, in the second set, in all four I 

 designations, it is nearer the pollen parent. I> 

 polariscopic figures and sel - and in the 



qualitative reactions with the chemical reagent- tlie 

 resemblance (except the iodine reaction in r 

 set ) is closer to the seed parent. In thn 

 development in excess of parental extreme-, and in 

 instance individuality, were recorded. The quantitative 

 reactions are most vagarious in their relations to the 

 qualitative reactions. It is of interest to note that the 

 seed parent is the same in both sets and that in both
