In this table, which is based on the F-, generation, only the four degrees, indicated by 

 the numbers 100, 75, 50, 0, of secondary branching have been recognised. 



^ Of these five plants two are of the sympodial type. One of these was dwarfed, and 

 the date of appearance of first flower consequently very late. The second produced 

 flowers at the extremities of the sympodial branches only. On account of these two 

 plants, which appear somewhat normal, the figure for this interval is abnormally low.
