AMARYLLIS — BRUNSVIGIA — BRUNSDONNA.

coarser and, as a rule, less oblique, and distortion and 

 bisection are much more frequent ; compound grains are 

 much more numerous. With selenite the quadrants are 

 less sharpl] defined, and impurity of both the blue and 

 orange, due to a grei ni b tint, i le - frequent. In the 

 itative and qualitative iodine reactions the colora 

 tion is ni' a deeper blue and more reddish than in 

 Amaryllis belladonna. 



In histological characters the grains of Brunsdonna 

 sandera alba are in form closer, on the whole, to those 

 of Amaryllis belladonna, bul in some respects closer to 

 Brunsvigia josephina. A typi oi ;rain peculiar to this 

 hybrid is noted which consists of an amorphous-looking 

 mass composed of a number of E I tins adheTenl to 

 the snlr or distal end of a large grain-mass, all inclosed 

 in 6 to 12 lamella'. The hilum more closely resembles 

 thai of Amaryllis belladonna; the lamellae in form and 

 arrangement are closer to those of Amaryllis belladonna, 

 but in aumber thej are clo er to Brunsvigia josephina; 

 in size and in proportions of length to breadth thi 



c to Amaryllis belladonna; in polariscopic figures 

 and lines and selenite reactions and in the qualitative 

 iodine reactions they exhibil a closer relationship to 

 [maryllis belladonna. The qualitative reactions with 

 the chemical reagents are, on the whole, much cL I 

 Amaryllis belladonna than to Brunsvigia josephina. 



In histological characters the grains of Brunsdonna 

 sandera arc in form much nearer to those of Amaryllis 

 ■ lonna than to those of the other parent, but they are 

 not so near those of .1 maryllis belladonna as those of the 

 other hybrid, and no! so near Brunsvigia josephina in the 

 number and type of compound grains as those of the other 

 hybrid. The hilum is the same as in the other hybrid, and 

 e nearer that of A maryllis belladonna. It differs from 

 the hilum of the other hybrid in being less often fissured; 

 lull il is more often fissured than in either parent. In 

 i haracter and eccentricity of the hilum these grains are 

 r those of the parents than those of the other hy- 

 brid. The lainelhe in character and arrangement closely 

 re i mble those of the other hybrid and are closer to those 

 of A maryllis &i Madonna than to those of the other parent, 

 hut in numbers thej are closer to Brunsvigia josephina. 

 Tn the ratio of length to breadth of the grains, and in 

 largi r rains in length, it is nearer to Amaryllis bella<- 



,. bul in the length of the nmon-sized grains 



it is nearer to Brunsvigia josephina. In polariscopic 

 properties in the character of the figure and appearance 

 with selenite this hybrid is closer to Amaryllis bella- 

 donna than to the other parent, hut not so rinse as the 

 other hybrid. In qualitative iodine reactions it is closer 

 to Amaryllis belladonna, but not so close as the other 

 hybrid. In the qualitative reactions with the chemical 

 reagents close relationship is shown to Amaryllis 



donna and to tl ther hybrid, bul closer on the whole 



to tin- parent than to the latter, tn some respei ts the 

 reactions are closer to Brunsvigia josephina than to 

 Amaryllis belladonna, showing the influences of both 

 parents. In the chloral-hydrate, nitric-acid, potassium- 

 sulphocyanate, and Bodium-salicylate reactions it is closer 

 to Amaryllis belladonna than to the other hybrid, but 

 in the cobalt-nitrate, copper-nitrate, and cupric-chloride 

 reactions it is closer to the other hybrid.
