Linaria vulgaris--crossed and self-fertilised flowers yielded seeds as:
14.
Vandellia nummularifolia--crossed and self-fertilised flowers yielded
seeds as: 67?
Gesneria pendulina--crossed and self-fertilised flowers yielded seeds as
(by weight): 100.
Salvia coccinea--crossed and self-fertilised flowers yielded seeds as
(about): 100.
Brassica oleracea--crossed and self-fertilised flowers yielded seeds as:
25.
Eschscholtzia californica--(English stock) crossed and self-fertilised
flowers yielded seeds as (by weight): 71.
Eschscholtzia californica--(Brazilian stock grown in England) crossed
and self-fertilised flowers yielded seeds (by weight) as (about): 15.
Delphinium consolida--crossed and self-fertilised flowers
(self-fertilised capsules spontaneously produced, but result supported
by other evidence) yielded seeds as: 59.
Viscaria oculata--crossed and self-fertilised flowers yielded seeds as
(by weight): 38.
Viscaria oculata--crossed and self-fertilised flowers (crossed capsules
compared on following year with spontaneously self-fertilised capsules)
yielded seeds as : 58.
Dianthus caryophyllus--crossed and self-fertilised flowers yielded seeds
as: 92.
Tropaeolum minus--crossed and self-fertilised flowers yielded seeds as:
92.
Tropaeolum tricolorum--crossed and self-fertilised flowers yielded seeds
as: 115. (9/1. Tropaeolum tricolorum and Cuphea purpurea have been
introduced into this table, although seedlings were not raised from
them; but of the Cuphea only six crossed and six self-fertilised
capsules, and of the Tropaeolum only six crossed and eleven
self-fertilised capsules, were compared. A larger proportion of the
self-fertilised than of the crossed flowers of the Tropaeolum produced
fruit.)
Limnanthes douglasii--crossed and self-fertilised flowers yielded seeds
as (about): 100.
Sarothamnus scoparius--crossed and self-fertilised flowers yielded seeds
as: 41.
Ononis minutissima--crossed and self-fertilised flowers yielded seeds
as: 65.
Cuphea purpurea--crossed and self-fertilised flowers yielded seeds as:
113.
Passiflora gracilis--crossed and self-fertilised flowers yielded seeds
as: 85.
Specularia speculum--crossed and self-fertilised flowers yielded seeds
as: 72.
Lobelia fulgens--crossed and self-fertilised flowers yielded seeds as
(about): 100.
Nemophila insignis--crossed and self-fertilised flowers yielded seeds as
(by weight): 69.
Borago officinalis--crossed and self-fertilised flowers yielded seeds
as: 60.
Nolana prostrata--crossed and self-fertilised flowers yielded seeds as:
100.
Petunia violacea--crossed and self-fertilised flowers yielded seeds as
(by weight): 67.
Nicotiana tabacum--crossed and self-fertilised flowers yielded seeds as
(by weight): 150.
Cyclamen persicum--crossed and self-fertilised flowers yielded seeds as:
38.
Anagallis collina--crossed and self-fertilised flowers yielded seeds as:
96.
