It is the usual expectation that when two white-flowered 

 varieties are crossed only white flowers should result. Table 9 

 shows that iu l)cans this is bj no means true. It comprises all 

 such crosses save one, Wardwell X Golden-eyed Wax, which 

 has been bred for three generations from the cross, yielding 

 about 100 plants, with none but Avhite flowxTs appearing. All 

 the rest of such crosses have yielded colored flowers in each 

 generation bred. All these crosses involve varieties one or both 

 of which bear pigmented seeds, these adding further evidence 

 that blossom color is governed largely by the pigmentation of 

 the seed coat.
