recognized for tbe separate sowings, and at most only for the total - 
and non-red (yellow) flowers. 
If the fourth and fifth columns of table IV for the number ot 
staminodes is split in the same way as in table VIII, according to 
the colour of leaves and flowers, it is found that the first four 
sowings produced twice as many plants with yellow flowers having 
2 or 2—38 staminodes as plants with red flowers, although the latter 
are two and a half times as numerous (205 as against 81).

Hence there is a tendency towards coupling between the factors 
for red flowers and those for 3 staminodes, especially clearly among 
the plants with red flowers and green leaves (B), which in table IX 
hardly occur among the last three sowings; the latter deviate con- 
siderably from the first four, in which such flowers are entirely 
wanting. It is among the non-red (yellow) individuals that most plants 
are found to be wholly or partially recessive for the characters of 
the staminode number. 
Summarizing we may conclude for the F2 offspring of the cross 
Canna glauca X C. indica, in which more hereditary 
factors were brought together than the number 
of chromosomes that 1) for the factors of the red
