ter. In the qualitative reactions with chloral hydrate,

 sodium saiii j late man] dift'i noted, some i 



striking bul mostlj seemingly of minor importance. 

 The starch of the hybrid N. dainty maid in compa 

 with the starches of the parents contains more ag n 

 gates than thai of .V. elegans and as many as in N. a 

 the irregularities are inure numerous than in N. elegans 

 and about the same as in the cither parent; and while most 

 of the grains in relative sizes of the proximal and distal 

 ends resemble those of N. crispa, there are more that 

 have the proximal end .-mailer than the distal end. The 

 hilum in distinctness is closer to X. crispa, while in the 

 absence o( fissuration it is closer to N. elegans; in eccen 

 tricitj it also is closer to the latter. The lamella 

 liner "than those of either parent, but nearer N. eh 

 while in general characters and arrangements they are 

 nearer N. crispa; the number is less than in either 

 parent, but nearer that of N. crispa. The size is some- 

 what closer to N. elegans. In the polarization, selenite, 

 and qualitative reactions the resemblances lean to one 

 or the other parent, but on the whole distinctly more to 

 N. elegans. In the qualitative reactions with chloral 

 hydrate, nitric acid, potassium iodide, potassium sulpho- 

 cyanate, potassium sulphide, and sodium salicylate cer- 

 tain of the phenomena lean to one parent and certain 

 others to the other parent, but the relationship is, on 

 the whole, distinctly closer to N. elegans. In comparison 

 with the starches of the parents the starch of the hybrid 

 N. queen of roses contains a larger number of aggregate-; 

 which have a larger number of component grains, and 

 more compound grains than in either parent; and the 

 latter are like those of N. elegans; the grains are less 

 regular than those of N. elegans but more regular than 

 those of N. crispa. The hilum is as distinct as in 

 N. crispa and more distinct than in the other parent; 

 it is rarely fissured, thus being closer to N. elegans; 

 and the eccentricity is greater than in either parent, 

 being nearer .Y. elegans. The lamelke in characters and 

 arrangements closely resemble those of N. crispa, but 

 the number is less than in cither parent and closer to that 

 of N. elegans. In size the grains are smaller than those 

 of either parent, and closer to those of .V. elegans. In 

 the polarization, selenite, and qualitative reactions with 

 iodine the resemblances are closer to .V. elegans. In the 

 qualitative reactions with chloral hydrate, nitric acid, 

 potassium iodide, potassium sulphocyanate, potassium 

 sulphide, and sodium salicylate certain of the phenomena 

 lean to one parent and certain others to the other. In 

 the reactions with chloral hydrate and sodium salicylate 

 fchey, on the whole, more closely resemble those of N. 

 crispa, but those with nitric acid, potassium iodide, potas 

 sium sulphocyanate, and potassium sulphide more i 

 resemble those of N. elegans. 



The two hybrids differ in certain very interesting 

 respects, especially as regards their greater resemblances 

 in their various properties to one or the other parent. 

 .V. dainty maid is in form more like N. crispa than 

 N. elegans, but in other histological re like 



the other parent. X. quern of ruses is in form and 

 hilum more like .V. elegans than N. crispa, but in the 

 lamellae it is nearer to N. crispa. In the polarization 

 properties both hybrid-: are closer to N. elegans than to 

 X. crispa, N. queen of roses being closer than .V. dainty 



In tin- iodine n both quantitative and 



qualitative, X. dainty maid more cl 

 elegans; but in the other hybrid, N. queen of roses, the 

 iiniirat.il grains show a closer relationship to N. elegans 

 and the heated ot gelatinized grains to the other pa

elegans than toN. crispa; while X. queen of roses is closer 

 to .V. crispa than to .V. elegans. In the qualitative reac- 

 tions with the various chemical 1 



individualities are reconi -rards interparental and 



inter-hybrid and parental-hybrid rea The hy- 



brids are sometimes practically alike and at others quite 

 as different from each other a- they are from the pan 

 or as the parent.- an- fn i other. The qualitative 



reactions may be closer to one or the other parent, accord- 

 ing to the reagent. In the chloral-hydrate reactions both 

 hybrids are closer to N. crispa, X. dainty maid being 

 the closer. In the reactions with nitric acid, potassium 

 iodide, potassium sulpho -mm sulphide 



the hybrids are closer to .V. elegans, X. dainty maid being 

 the closer. In the sodium-salicylate n X. dainty 



maid is nearer to .\ . and .Y. queen of ro 



to .Y. crispa, there being nearly as much difference be- 

 tween the hybrids themselves as between the hybrid 

 .Y. queen of roses and the parent N. elegans.
