Primula sinensis.

In all four pots plants derived from an illegitimate cross between distinct plants flowered before any one of the self-fertilised plants.

Primula sinensis.

A legitimately crossed plant flowered before any one of the self-fertilised plants in seven out of the eight pots.

A legitimately crossed plant flowered from one to two days before any one of the self-fertilised plants in all three pots.

Zea mays.

In all four pots a crossed plant flowered first.

Phalaris canariensis.

The crossed plants flowered before the self-fertilised in the open ground, but simultaneously in the pots.

SPECIES OF WHICH THE FIRST PLANTS THAT FLOWERED WERE OF SELF-FERTILISED PARENTAGE.

Eschscholtzia californica (First Generation).

The crossed plants were at first taller than the self-fertilised, but on their second growth during the following year the self-fertilised exceeded the crossed in height, and now they flowered first in three out of the four pots.

Lupinus luteus.

Although the crossed plants were to the self-fertilised in height as 100 to 82; yet in all three pots the self-fertilised plants flowered first.

Clarkia elegans.

Although the crossed plants were, as in the last case, to the self-fertilised in height as 100 to 82, yet in the two pots the self-fertilised flowered first.

Lobelia fulgens (First Generation).

The crossed plants were to the self-fertilised in height only as 100 to 127, and the latter flowered much before the crossed.

Petunia violacea (Third Generation).

The crossed plants were to the self-fertilised in height as 100 to 131, and in three out of the four pots a self-fertilised plant flowered first; in the fourth pot simultaneously.

Petunia violacea (Fourth generation).

Although the crossed plants were to the self-fertilised in height as 100 to 69, yet in three out of the five pots a self-fertilised plant flowered first; in the fourth pot simultaneously, and only in the fifth did a crossed plant flower first.

Nicotiana tabac.u.m (First Generation).

The crossed plants were to the self-fertilised in height only as 100 to 178, and a self-fertilised plant flowered first in all four pots.

Nicotiana tabac.u.m (Third Generation).

The crossed plants were to the self-fertilised in height as 100 to 101, and in four out of the five pots a self-fertilised plant flowered first.

Canna warscewiczi.

In the three generations taken together the crossed were to the self-fertilised in height as 100 to 101; in the first generation the self-fertilised plants showed some tendency to flower first, and in the third generation they flowered first in nine out of the twelve pots.

SPECIES IN WHICH THE CROSSED AND SELF-FERTILISED PLANTS FLOWERED ALMOST SIMULTANEOUSLY.

Mimulus luteus (Sixth Generation).

The crossed plants were inferior in height and vigour to the self-fertilised plants, which all belonged to the new white-flowered tall variety, yet in only half the pots did the self-fertilised plants flower first, and in the other half the crossed plants.

Viscaria oculata.

The crossed plants were only a little taller than the self-fertilised (namely, as 100 to 97), but considerably more fertile, yet both lots flowered almost simultaneously.
