parent in Sets 9 and 10. As a hybrid it exhibits mark- 

 edly biparental inheritance in all of the designations 

 in varying degrees in relation to one or the other parent, 

 but leaning, on the whole, strongly to the seed parent; 

 not exhibiting any notable peculiarity that is not ob- 

 served in one or the other parent, nor showing any de- 

 velopment in excess or deficit of parental development, 

 except in certain histologic features of minor character. 

 As a seed parent it shows in Set 9 less potency, and in 

 Set 10 about equal potency, compared with the other 

 parent in determining the properties of the hybrid. 

 N. madame de graaff shows in its qualitative reactions 

 with the various chemical reagents the peculiar processes 

 of gelatinization that were recorded in the reactions of 

 one parent or both parents ; and the processes of this hy- 

 brid are manifested in its offspring in a manner not dis- 

 tinguishable from that which on general principles 

 should be expected were it a species or a variety and 

 not a hybrid. 



The quantitative reactions bear to the histologic prop- 

 erties and qualitative reactions the most variable rela- 

 tionships in their parental leanings.

In histologic properties and qualitative reactions 

 L. marhan bears in three-fourths of its designations a 



closer relationship to the pollen parent. In form and 

 size of the grains the relationship is closer to the pollen 

 parent; but in hilum and lamellae the reverse. Apart 

 from the chloral hydrate reaction, which is closer to the 

 seed parent, all of the qualitative reactions are closer to 

 the pollen parent. L. dalhansoni in form, size, charac- 

 ter, and arrangement of the lamellae is closer to the 

 seed parent, but in hilum and number of the lamellae 

 is closer to the pollen parent. In only the chloral- 

 hydrate reaction is the hybrid closer in the qualitative 

 reactions to the pollen parent, and in the others closer 

 to the seed parent, the opposite to what was noted in 

 the first hybrid. Each of these hybrids has the same 

 pollen parent, but there is an almost entire reversal 

 of the parental relationships in the'various designations. 

 In L. golden gleam the relationship is, with the single 

 exception of the chloral-hydrate reaction, closer to the 

 seed parent. The pollen parent of L. marhan is the 

 same as the seed parent of L. golden gleam, the hybrid 

 relationships of each being closer to the seed parent, 

 L. maculatum and L. ienuifolium, respectively. L. tes- 

 taceum in form and in character of the hilumi and lamellae 

 is closer to the seed parent, but in eccentricity of the 

 hilum and in size it is closer to the pollen parent. In 

 all of the qualitative reactions it is shown to be closer
