Ipomoea purpurea.

I record in my notes that in all ten generations many of the crossed plants flowered before the self-fertilised; but no details were kept.

Mimulus luteus (First Generation).

Ten flowers on the crossed plants were fully expanded before one on the self-fertilised.

Mimulus luteus (Second and Third Generation).

In both these generations a crossed plant flowered before one of the self-fertilised in all three pots.

Mimulus luteus (Fifth Generation).

In all three pots a crossed plant flowered first; yet the self-fertilised plants, which belonged to the new tall variety, were in height to the crossed as 126 to 100.

Mimulus luteus.

Plants derived from a cross with a fresh stock as well as the intercrossed plants of the old stock, flowered before the self-fertilised plants in nine out of the ten pots.

Salvia coccinea.

A crossed plant flowered before any one of the self-fertilised in all three pots.

Origanum vulgare.

During two successive seasons several crossed plants flowered before the self-fertilised.

Brassica oleracea (First Generation).

All the crossed plants growing in pots and in the open ground flowered first.

Brassica oleracea (Second Generation).

A crossed plant in three out of the four pots flowered before any one of the self-fertilised.

Iberis umbellata.

In both pots a crossed plant flowered first.

Eschscholtzia californica.

Plants derived from the Brazilian stock crossed by the English stock flowered in five out of the nine pots first; in four of them a self-fertilised plant flowered first; and not in one pot did an intercrossed plant of the old stock flower first.

Viola tricolor.

A crossed plant in five out of the six pots flowered before any one of the self-fertilised.

Dianthus caryophyllus (First Generation).

In two large beds of plants, four of the crossed plants flowered before any one of the self-fertilised.

Dianthus caryophyllus (Second Generation).

In both pots a crossed plant flowered first.

Dianthus caryophyllus (Third Generation).

In three out of the four pots a crossed plant flowered first; yet the crossed were to the self-fertilised in height only as 100 to 99, but in weight as 100 to 49.

Dianthus caryophyllus.

Plants derived from a cross with a fresh stock, and the intercrossed plants of the old stock, both flowered before the self-fertilised in nine out of the ten pots.

Hibiscus africanus.

In three out of the four pots a crossed plant flowered before any one of the self-fertilised; yet the latter were to the crossed in height as 109 to 100.

Tropaeolum minus.

A crossed plant flowered before any one of the self-fertilised in three out of the four pots, and simultaneously in the fourth pot.

Limnanthes douglasii.

A crossed plant flowered before any one of the self-fertilised in four out of the five pots.

Phaseolus multiflorus.

In both pots a crossed plant flowered first.

Specularia speculum.

Lobelia ramosa (First Generation).

In all four pots a crossed plant flowered before any one of the self-fertilised.

Lobelia ramosa (Second Generation).

Nemophila insignis.

In four out of the five pots a crossed plant flowered first.

Borago officinalis.

Petunia violacea (Second Generation).

In all three pots a crossed plant flowered first.

Nicotiana tabacum.

A plant derived from a cross with a fresh stock flowered before any one of the self-fertilised plants of the fourth generation, in fifteen out of the sixteen pots.

Cyclamen persicum.

During two successive seasons a crossed plant flowered some weeks before any one of the self-fertilised in all four pots.
