to the seed parent. L. iurbanki in form, lamellae, and 

 size is closer to the seed parent, but in hilum closer to 

 the pollen parent. Except the polariscopic figure and 

 selenite reaction it is closer in all of the qualitative 

 designations to the seed parent. Excess and deficit of 

 development are recorded only among the histologic prop- 

 erties, and no individuality is noted in any of the five 

 hybrids in any of the designations. 



The quantitative jeactions bear most variable and in- 

 dependent relationships to the qualitative reactions in 

 each of the sets of parents and hybrid.
