Pot 5 : 31 : 18.
Pot 5 : 16 : 11 4/8.
Pot 6 : 20 : 32 4/8.
Total : 197.0 : 210.5.
The average height of the eight crossed plants is 24.62, and that of the
eight self-fertilised 26.31 inches; or as 100 to 107. So that the
self-fertilised had a decided advantage over the crossed. But the plants
from some cause never grew well, and finally became so unhealthy that
only three crossed and three self-fertilised plants survived to set any
capsules, and these were few in number. The two lots seemed to be about
equally unproductive.
17. PASSIFLORACEAE.--Passiflora gracilis.
This annual species produces spontaneously numerous fruits when insects
are excluded, and behaves in this respect very differently from most of
the other species in the genus, which are extremely sterile unless
fertilised with pollen from a distinct plant. (5/17. 'Variation of
Animals and Plants under Domestication' chapter 17 2nd edition volume 2
page 118.) Fourteen fruits from crossed flowers contained on an average
24.14 seeds. Fourteen fruits (two poor ones being rejected),
spontaneously self-fertilised under a net, contained on an average 20.58
seeds per fruit; or as 100 to 85. These seeds were sown on the opposite
sides of three pots, but only two pairs came up at the same time; and
therefore a fair judgment cannot be formed.
