--Highly fertile.
Viscaria oculata (Caryophyllaceae).--Produces plenty of capsules with
good seeds.
Stellaria media (Caryophyllaceae).--Covered-up and uncovered plants
produced an equal number of capsules, and the seeds in both appeared
equally numerous and good.
Beta vulgaris (Chenopodiaceae).--Highly self-fertile.
Vicia sativa (Leguminosae).--Protected and unprotected plants produced
an equal number of pods and equally fine seeds. If there was any
difference between the two lots, the covered-up plants were the most
productive.
Vicia hirsuta.--This species bears the smallest flowers of any British
leguminous plant. The result of covering up plants was exactly the same
as in the last species.
Pisum sativum (Leguminosae).--Fully fertile.
Lathyrus odoratus (Leguminosae).--Fully fertile.
Lathyrus nissolia.--Fully fertile.
Lupinus luteus (Leguminosae).--Fairly productive.
Lupinus pilosus.--Produced plenty of pods.
Ononis minutissima (Leguminosae).--Twelve perfect flowers on a plant
under a net were marked by threads, and produced eight pods, containing
on an average 2.38 seeds. Pods produced by flowers visited by insects
would probably have contained on an average 3.66 seeds, judging from the
effects of artificial cross-fertilisation.
Phaseolus vulgaris (Leguminosae).--Quite fertile.
Trifolium arvense (Leguminosae).--The excessively small flowers are
incessantly visited by hive and humble-bees.
