tin- pollen parent. In the histologic properties and 

 qualitative reactions, in the first set the hybrid show* 

 throughout the designation* a markedly closer relation- 

 chip, on the whole, to ('. trylann-um (the pollen parent) 

 than to C. moorri (the seed parent) ; while in the third 

 M t tin- hybrid shows a eloser relationship. n the whole, 



riumrri (the pollen parent) than to C. lowifolium 



(the seed parent). In the first set C. moorei (hardy) 



is croMed with C. :rylanirum (tender), the two specie* 



being well separated, the hybrid leaning strongly to the 



p:irmt I'. :ryliinirnm. In the second set C. nry- 



lanifvm (tender) is crossed with C. longifoli urn (hardy), 



the specie* are well separated, the hybrid leaning 



-;r..!,_'l\. hut leas strongly than in the preceding set, 



tlanifuim. In the third not C.*longi folium 



(hardy) is crossed with C. moorei (hardy), the species 



comparatively close, the hybrid tending to be, on 



id- whole, distinctly closer to C. moorei (the pollen 



t ) than to C. longifolium. The shifting of paren- 

 tal potency in relation to hybrid development is of inter- 

 est, C. xeylanifvm being the more potent aa both pollen 

 and seed parent in relation to C. moorei and C. longi- 

 folium, respectively, and C. moorei being more potent 

 than C. longifolium. The quantitative in comparison 

 with the qualitative reactions are of great interest. In 

 the first set there is strong leaning to the pollen parent; 

 in the second set to intermediatenees and to the seed 



rather than to the pollen parent ; and in the third set 

 almost wholly to the pollen parent, in each the inclina- 

 tion* being in harmony with the leanings, on the whol , 

 of the qualitative reactions. 



NEUNB. (TABLE C 6.) 



The first two hybrids vary in a most interesting man- 

 ner in their resemblances and differences in regard to 

 each other and to their parents ; and they differ from each 

 other almost as much as they do from the parents, or 

 as the parents differ from each other. Piparental inheri- 

 tance showing varying degrees of influence of each parent 

 is manifest throughout the designations. The hybrid 

 2V. quern of reset differs in the form of the grains from 

 the other hybrid by a greater resemblance to N. erispa 

 because of its grains having a more regular form, more 

 aggregates, and more compound grains. The hybrids 

 more closely resemble each other than either parent in 

 the character of the hilum, and both are closer in this 

 feature of N. elegant than to N. erispa. The lamella; of 

 \. i/uftn of roses are clow* than those of the other hybrid 

 to those of N. erispa, while those of .V. dainty maid are 

 closer to those of the other parent. The size of the 

 grains of .V. queen of roses ia less than that of the other 

 hybrid, but it is closer to that of the latter than the 

 latter is to either parent, yet not so close as is that of 

 A*, dainty maid to that of .V. elegant. In the polari-
