The intercrossed plants thus have at least one important advantage over the self-fertilised.

These intercrossed plants thus became in the later generations more or less closely inter-related.

So that here again the self-fertilised exhibit a slight superiority over the intercrossed plants.

Column 4: Number of the plants from self-fertilised or intercrossed parents of the same stock.

Indeed, in two of the cases the self-fertilised plants were superior to such intercrossed plants.

These consequently exceeded the intercrossed plants considerably in height.

Several plants were raised in the greenhouse close together, and their flowers were mutually intercrossed.

Their leaves were of a brighter green than those of the intercrossed and self-fertilised plants.

The flowers of the intercrossed plants of the fourth generation were likewise nearly uniform in colour.

In sixteen out of these nineteen pairs, the Colchester-crossed plant exceeded in height its intercrossed opponent.

The forty-five capsules (the five empty ones included) from the intercrossed plants contained 2240 seeds.

The Westerham-crossed plants in height to the intercrossed as 100 to 119.

The intercrossed plants in height to the self-fertilised as 100 to 77.

The Westerham-crossed plants in weight to the intercrossed as 100 to 101.

The intercrossed plants in weight to the self-fertilised as 100 to 22.3.

Mimulus luteus-theintercrossed plants are derived from a cross between two plants of the 8th self-fertilisedgeneration.
