As the plants did not grow to their proper height in the above small
pots in Table 6/84, four crossed and four self-fertilised plants were
raised from the same seed, and were planted in pairs on the opposite
sides of four very large pots containing rich soil; so that they were
not exposed to at all severe mutual competition. When these plants were
in flower I neglected to measure them, but record in my notes that all
four self-fertilised plants exceeded in height the four crossed plants
by 2 or 3 inches. We have seen that the flowers on the original or
