Crowded plants.
Total : 581.63 : 349.36.
The thirteen crossed plants here average 44.74, and the thirteen
self-fertilised plants 26.87 inches in height; or as 100 to 60. The
crossed parents of these were much taller, relatively to the
self-fertilised parents, than in the last case; and apparently they
transmitted some of this superiority to their crossed offspring. It is
unfortunate that I did not turn these plants out of doors, so as to
observe their relative fertility, for I compared the pollen from some of
the crossed and self-fertilised plants in Pot 1, Table 6/81, and there
was a marked difference in its state; that of the crossed plants
contained hardly any bad and empty grains, whilst such abounded in the
pollen of the self-fertilised plants.
THE EFFECTS OF A CROSS WITH A FRESH STOCK.
I procured from a garden in Westerham, whence my plants originally came,
a fresh plant differing in no respect from mine except in the colour of
the flowers, which was a fine purple.
