The chief hybrids are between the "Dwarf Purple" (6), "Ford- 

 hook Improved" (14) and "Pride of Sunnyside" (20). Flower 

 clusters with an open blossom from a large number of plants of 

 these hybrids are brought together in Plate XVII. In the upper 

 left hand corner are a few blooms from a representative of the 

 "American" species and, scattered among them, a few of the "Chi- 

 nese"' kind, the latter being easily distinguished by their smaller 

 size, apparent whiteness of the corolla and, last but not least, the 

 stout "spines" that are upon the stems. To the right of the par- 

 ents are thirteen clusters from as many plants of the hybrid 

 "Dwarf Purple" upon "Chinese," one generation after the blend. 

 It is seen that from 2 to 13 there are two blossoms (4 and 10) 

 that are larger and evidently darker colored than the others ; Nos. 

 2 and 8 are quite small and nearly white, particularly the latter. 

 From 14 to 19 are the reciprocals of the same hybrid in the same 

 generation, in which the variations are practically the same as for 

 the first group. The set from20 to 35 is of "Fordhook" upon "Chi- 

 nese" in the second generation from the blend, that is, one year 

 further on than the set previously considered. Here, certain blos- 

 soms are conspicuous for their large size and purple color as, for 

 example, Nos. 21, 30, 31 and 35, while others, as Nos. 20, 22, 23, 

 24, 26 and 29, are small and generally white. There are some 

 that are intermediate, but the individual differences are not easily 

 determined from a picture; if 26 is compared closely with 34 

 the great contrast in size and number of particular parts is ap- 

 parent. The four numbers from 36 to 39 are of the blend of 

 "Pride of -Sunnyside" upon the "Chinese" and the uniformity of 

 the blossoms is fairly well shown. 



The whole lower third of the picture, including Nos. 40 to 62, 

 are of the hybrid in which the "American" blood is cut down to 

 a quarter by breeding the first hybrid to the "Chinese" again. 

 The blossoms average smaller than elsewhere, and there are but 

 a few that show the purple color and the larger size suggesting 

 the "American ;" Nos. 48 and 54 are, perhaps, the largest of these, 

 and their corollas are thin and pale as well as small as compared 

 with the purple parent given in i. 



There is no great satisfaction in showing the flowers as a 

 means of illustrating the individual differences in plants of a hy-
