III.] RESEMBLANCE OF SEED AND BUD -VARIETIES. 95 



rience knows. I will cite a single case of "sporting" 

 in bud offspring. One winter a chance tomato plant 

 came up in one of my greenhouses. I let it grow, and 

 it bore fruit quite unlike any other variety which I ever 

 saw. There was no other tomato plant in the house. 

 I propagated it both by seeds and cuttings. I had two 

 generations of cuttings. Those taken directly from 

 the parent plant "came true," or very nearly so; then 

 a lot of cuttings from these cutting- grown plants was 

 taken, making the second asexual generation from the 

 original seedling. While most of the seeds "came 

 true," few of these second cuttings did, and, moreover, 

 they ' ' sported ' ' into several very unlike forms — so 

 much unlike that I had both red and yellow fruits 

 from them. In respect to transmission of characters, 

 then, bud and seed -varieties are alike, because either 

 class may or may not transmit its marks either by 

 seeds or buds. 



Finally, let me say, in proof of the further similarity 

 of bud and seed -variations, that each class follows the 

 incidental laws of external resemblance which pertain to 

 the other class. For instance, there are analogous vari- 

 ations in each, giving rise to the same kinds of variega- 

 tion, the same anomalies of cut and colored foliage, of 

 weeping branches, party-colored fruits and the like; 

 and the number of similar variations may be as great 

 for any ameliorated plant in the one class as in the 

 other. The most expert observer is not able to dis- 

 tinguish between bud -varieties and seed -varieties ; the 

 only way of distinguishing the two is by means of 

 the re(;ords of their origins, and because such records 

 of any varieties are few we have come to overlook the 

 frequency of bud -variation, and to associate all pro-
