Lathyrus odoratus (Second Generation).
Although the crossed plants were to the self-fertilised in height as 100
to 88, yet there was no marked difference in their period of flowering.
Lobelia fulgens (Second Generation).
Although the crossed plants were to the self-fertilised in height as 100
to 91, yet they flowered simultaneously.
Nicotiana tabacum (Third Generation).
Although the crossed plants were to the self-fertilised in height as 100
to 83, yet in half the pots a self-fertilised plant flowered first, and
in the other half a crossed plant.]
These three lists include fifty-eight cases, in which the period of
flowering of the crossed and self-fertilised plants was recorded. In
forty-four of them a crossed plant flowered first either in a majority
of the pots or in all; in nine instances a self-fertilised plant
flowered first, and in five the two lots flowered simultaneously. One of
the most striking cases is that of Cyclamen, in which the crossed plants
flowered some weeks before the self-fertilised in all four pots during
two seasons. In the second generation of Lobelia ramosa, a crossed plant
flowered in all four pots some days before any one of the
self-fertilised. Plants derived from a cross with a fresh stock
generally showed a very strongly marked tendency to flower before the
self-fertilised and the intercrossed plants of the old stock; all three
lots growing in the same pots.
