LARGE FLORAL DISPLAYS INCREASE SELF-POLLINATION BUT DO NOT AFFECT VISITATION RATES IN CLARKIA CONCINNA

Madroño
Optimal floral display (the number of simultaneously open flowers) is frequently viewed as a balance between pollinator attraction and avoidance of pollinator-mediated interfloral selfing (geitonogamy).

Temporal patterns in the mass flowering of Firmiana simplex: A new case of duodichogamy.

American-Eurasian journal of botany
PREMISE Given that insect-pollinated trees are generally characterized by mass flowering, hermaphrodites may benefit from abundant pollinators but suffer the cost of geitonogamy.

Seed quality and germination performance increase with cross-pollination in members of subtribe Orchidinae (Orchidaceae)

Botanical journal of the Linnean Society
Over half of angiosperms have self-incompatibility systems to avoid self-pollination and inbreeding depression. Many members of Orchidaceae are self-compatible, but they may be prone to negative consequences of self-pollination.
