There were seventeen crossed plants; but one did not produce a flower-stem.

In three out of the four pots, the crossed plants flowered first.

The crossed plants during this season, as during the last, flowered first.

In all four pots the crossed plants flowered some days before the self-fertilised.

The crossed plants were, however, inferior in fertility to the self-fertilised.

So that the excess of height of the crossed plants is quite insignificant.

So that the crossed plants were very much more productive than the self-fertilised.

The crossed plants, however, were on the whole considerably taller than the self-fertilised.

On the other hand, all the crossed plants without exception were growing vigorously.

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

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

The crossed plants flowered before the self-fertilised in both pots.

The crossed plants in both pots flowered before the self-fertilised.

In both pots a self-fertilised plant flowered before any one of the crossed plants.

All the crossed plants together produced thirty-three flower-stems, whilst the self-fertilised bore only thirteen.

So that the crossed plants now showed a decided advantage over their self-fertilised opponents.
