--Fully self-fertile.
Ipomoea purpurea (Convolvulaceae).--Highly self-fertile.
Leptosiphon androsaceus (Polemoniacae).--Plants under a net produced a
good many capsules.
Primula mollis (Primulaceae).--A non-dimorphic species, self-fertile: J.
Scott, in 'Journal of the Linnean Society Botany' volume 8 1864 page
120.
Nolana prostrata (Nolanaceae).--Plants covered up in the greenhouse,
yielded seeds by weight compared with uncovered plants, the flowers of
which were visited by many bees, in the ratio of 100 to 61.
Ajuga reptans (Labiatae).--Set a good many seeds; but none of the stems
under a net produced so many as several uncovered stems growing closely
by.
Euphrasia officinalis (Scrophulariaceae).--Covered-up plants produced
plenty of seed; whether less than the exposed plants I cannot say. I saw
two small Dipterous insects (Dolichopos nigripennis and Empis chioptera)
repeatedly sucking the flowers; as they crawled into them, they rubbed
against the bristles which project from the anthers, and became dusted
with pollen.
Veronica agrestis (Scrophulariaceae).--Covered-up plants produced an
abundance of seeds. I do not know whether any insects visit the flowers;
but I have observed Syrphidae repeatedly covered with pollen visiting
the flowers of V. hederaefolia and chamoedrys.
Mimulus luteus (Scrophulariaceae).--Highly self-fertile.
Calceolaria (greenhouse variety) (Scrophulariaceae).
