Self-pollination limits the variety of progeny and may depress plant vigor.

More scientific research will need to be carried out, eg, artifical controlled cross-pollination experiments to confirm the ability of Bauhinia blakeana in backcross or outcross to produce (fertile) seeds.
Many Bulbophyllum species have the typical odor of rotting carcasses, and the flies they attract assist in their reproduction through pollination.
Hernán Cortés brought vanilla to Europe, but for more than 300 years the pollination mechanism remained a mystery.
The symphony is also noted for its live performances; despite the fact that "Cross-Pollination" has not been played live, "Overture" has been performed at virtually every date on The Resistance Tour, besides festival appearances (although it had been played at one or two of the festival slots, this was however rare).
Webster's research included study of the diverse family Euphorbiaceae (spurges), on which he produced a large number of papers, and he lectured on plant systematics, biogeography, and the ecology of pollination.
The loganberry (Rubus × loganobaccus) is an hexaploid hybrid produced from pollination of a plant of the octaploid blackberry cultivar 'Aughinbaugh' (Rubus ursinus) by a diploid red raspberry (Rubus idaeus).
In 1888, Lue cross-pollinated the "Harts late" Valencia and "Mediterranean Sweet" orange varieties, which produced a fruit both sweet and frost-tolerant.
virginica is adapted primarily to nocturnal pollination by medium sized moths and larger sphinx moths.
From the rarity of buzz-pollination on their host plant, it is thought that the genus Cyclamen co-evolved with large bees capable of buzz-pollination, but lost its original pollinators for unknown historical reasons.
The flowers are pollinated by a variety of insects including the hawkmoth Hyles lineata and flies of the genera Anthomyia and Tachypeza.
He suggested that, to understand the Global Indians, one should study (1.) Monarch (butterfly) (multi-generation round trip between south and North America), (2.) Blue Wildebeest (survival of blue wildebeest over the black wildebeest that are extinct now), and the (3.) Bees (how they are essential for existence of human life by being the pollination agent for plants).
1961 marked a turning point in the life of the Evangelical Church when younger men were invited to attend a Billy Graham crusade which resulted in a cross pollination of religious ideals from the United States with those of 1960's England.
Pollination occurs probably by insects, although the flowers are visited by many birds such as tanagers, hummingbirds and orioles.
