SUMMARIES OF THE HISTOLOGIC CHARACTERS,

figure, and selenite reactions. /. dorak shows even a 

 strongei leaning to the seed parent, i lo em m 

 to the pollen parent being recorded in onlj 

 tricity of the hilum and lamellae. The seed parent of 

 these hybrids is the same and it shows in both hybrid 

 much greater potency than the other parent. In /. mrs. 

 alan grey the form, hilum, and indistinctness of the 

 lamella' lean to the seed parent, but the general charac- 

 ters of the Iamellse and the size of the grains incline 

 to the pollen parent. Among the qualitative reactions, 

 in those with iodine alone is there greater closeness to 

 the seed parent. /. dordk and /. mrs. alan grey have 

 /. cengialti as their pollen and seed parent, respectively; 

 in each hybrid this parent exhibits the lesser influence 

 mi the histologic characters and qualitative reactions 

 of the hybrids. /. pursind shows, with the exception 

 of eccentricity of the hilum and qualitative reactions 

 with iodine, a closer relationship to the seed parent. De- 

 ficit and excess of development, mostlj in histologic 

 properties, are occasionally noted; but individualities of 

 the hybrids are absent. 



The independence and vagariousness of the quantita- 

 tive reactions in relation to the qualitative reactions are 

 very striking in all of the sets. 



Gladiolus. (Table C 9.) 



The seed parent of G. colvillei shows throughout 

 the histologic properties and qualitative reactions, the 

 more potent influence on the hybrid, excepting in the 

 eccentricity of the hilum and the lamella?, in the former 

 respect being subordinate, and in the latter of equal 

 value, to the seed parent. Excess of development of 

 parental extremes was noted in the lamella 3 , and indi- 

 viduality was recorded in the hydrochloric-acid reaction. 



In the quantitative reactions there is mostly a tend- 

 ency to sameness as both parents, together with some 

 inclination to excess and deficit of development ; but, on 

 the whole, the leaning is rather toward the seed parent. 



Tritonia. (Table C 10.) 



This hybrid in its designations shares about equally 

 in closeness to one or the other parent. In eccentricity 

 of the hilum, lamella 1 , and size it is closer to the seed 

 parent, but in form and character of the hilum closer to 

 the pollen parent. In the polariscopic figure, and in the 



id iodini r to the 



parent, but in all the othi r qrj ditativi it is 



i parent, I ■: de- 



velopment and individualitii not noted. I 



ously, while in the qualitative reactions with the various 

 chemical reagents the li of the hybrid is to the 



pollen parent, in the quantitative reactions th 

 tion is in all seven reactions to the seed parent. This 



id quant;' 

 parental relationships is bj no mi mmon, as will 



ii in other tables.

group. In all four hybrids there is among the 



il properties a manifest ti to a splitting 



of the characters in their parental n ' 

 solely in the form of the grains) and to duel 

 given characters in different hybrids to om or the 



other. The form of the grains in B. mrs. heal, B. Julius, 

 and B. success is closer to the pollen parent, but in B. 

 ensign closer to the ether parent. The hilum in charac- 

 in ]',. mrs. heal, B. ensign, and B. success closer 

 to the seed parent, but in B. Julius closer to the pollen 

 parent; while in eccentricity it is closer in all to the 

 pollen parent. The lamellae in character are in B. en- 

 sign and B. Julius closer to the pollen parent, while in 

 number this property is in all four closer to the : 

 patent. In size, in common sizes it is in B. mrs. heal and 

 B. success closer to the seed parent, in the larger grains 

 in /.'. ensign closer to the pollen parent, and in propor- 

 tion of length to breadth in /•'. julius cl ser to the pollen 

 parent. The polariscopic figure is in B. mrs. heal I 

 to the seed parent, but in the other three the same as 

 both parents or closer to the pollen parent. The selenite 

 reactions arc closer to those of the seed parent in B. mrs. 

 heal and B. ensign; closer to those of the pollen parent 

 in 11. success; and the same a-s both parents in B. julius. 

 The indepi ndence of polariscopic liL r ure and selenite 

 reaction is illustrated in 11. ensign. In the iodine i 

 tions the inclinations may be to one or the oilier parent, 

 but in B. julius there is a splitting so that the reactions 

 of the gelatinized grains are closer to the seed parent,
