tin' pollen parent. In the histologic properties and 

 qualitative reactions, in the first set the hybrid shows 

 throughout the designations a markedly closer relation 

 sliip, on the whole, to C. zeyhuiirum (tin- pollen parenl I 

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

 se1 the hybrid shows a closer relationship, on the whole, 

 to C. moorei (the pollen parenl ) than to C. longifolium 

 (the seed parent). In the firsi Bet C. moorei (hardy) 

 is crossed with C. zeylanicum (tender), the two species 

 being well separated, the hybrid leaning strongly to the 

 pollen parent C. zeylanicum. In the second set C. zey- 

 lanicum (tender) is crossed with G. lo ngifolium (hardy), 

 the species are well separated, the hybrid leaning 

 strongly, but less strongly than in the preceding set, 

 to C. zeylanicumi. In the third set C. longifolium 

 (hardy) is crossed with C. moorei (hardy), the spe ies 

 being comparatively close, the hybrid tending to be, on 

 the whole, distinctly closer to 0. moorei (the pollen 

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

 tal potency in relation to hybrid development is of inter- 

 est, C. zeylanicum being the more potent as both pollen 

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

 folium, respectively, and G. moorei being more potent 

 than G. 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 intermediateness and to the seed 



rather than to the pollen parent; and in the third 

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

 tions being in harmony with the leanings, on the whole, 



of the qualitative n 



Nerine. (Table C i>.) 



The first two hybrids vary in a most interesting man- 

 ner in their resemb ul differences in i 

 each other and to their parents ; and thej d ffei from each 

 other almost as much as they do from the parenl 

 as the parents differ from each other. Biparental inheri- 

 tance showing varying di of each parent 

 is manifest throughout the tions. The hybrid

the other hybrid by a greater resemblance to N. crispa 



i e of its grains having a more n rm, more 



aggregates, and more compound grains. The hybrids 



more closely resemble each other than either parent iii 

 the character of the hilum, and both are a this 



feature of N. elegans than to X. crispa. The lame:

to those of X. crispa, while those of A*, dainty maid are 

 closer to those of the other parent. Tl f the 



grains of X. queen of roses is less than that of the 

 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 

 N. dainty maid to that of .Y. elegans. In the polari-
