“…Of these, C. flavum is unique in being pollinated by a mix of Andrena bee species, bumblebee workers, and blow flies that breed in carrion (Bänziger et al 2005;Zheng et al 2011). The other fly-pollinated Cypripedium species are narrow specialists, having highly evolved flowers that mimic the materials in which their pollinators breed.…”

AbstRAct. Cypripedioideae (five genera; ca. 176 species) are widespread in temperate and tropical Asia and America. About a quarter (42) of the species have been studied to determine their pollinators and/or breeding systems. All flowers are one-way traps pollinated by insects of particular types and size. Slipper orchids are selfcompatible and pollinated by deceit. Most Cypripedium species are pollinated by bees, whereas some smallerflowered species are pollinated by flies, and a few are pollinated by both. Most bee-pollinated Cypripedium species appear to be generalized food mimics. The fly-pollinated species have evolved diverse pollination systems that utilize a variety of flies as pollen vectors, including fruit flies, dung flies, and a fungal spore-eating hoverfly (Syrphidae). Most species of the tropical Asian Paphiopedilum and tropical American Phragmipedium are pollinated by hoverflies; flowers of many species in both genera have aphid-like spots that attract gravid female hoverflies that normally lay their eggs in aphid colonies. The more brightly colored Paphiopedilum micranthum and Phragmipedium besseae are pollinated by Hymenoptera. Autogamy is limited but occurs most frequently in Phragmipedium species. About two-thirds of the insect-pollinated slipper orchids (25/37) have evolved highly specialized flowers that are pollinated by a single pollinator or several pollinator species in the same genus. Species belonging to the same taxonomic section usually have the same pollination system. The deceit-pollination system of Cypripedioideae appears to have evolved early in diversification of Orchidaceae..

“…Identified pollinators include a parasitic wasp (Cinetus sp. ; Diapriidae), small-bodied bees (e.g., Andrena and Lasioglossum), medium-bodied bees (e.g., Megachile and Anthophora), bumblebees, hoverflies, fruit flies, dung flies, and blowflies (e.g., Nilsson 1979;Ferguson & Donham 1999;Bänziger et al 2008;Edens-Meier et al 2011;Ren et al 2011Ren et al , 2012Zheng et al 2011;Li et al 2012;Suetsugu & Fukushima 2013).…”

Cypripedium macranthos sensu lato typically has purple-pink flowers with no nectar and harvestable pollen. On Rebun Island, Hokkaido, Japan, purple-pink-flowered C. macranthos var. macranthos individuals rarely grow among numerous pale-creamflowered C. macranthos var. rebunense plants. In both varieties, flower size is similar, their flowering periods completely overlap, and they share the same pollinator (Bombus pseudobaicalensis). However, in only one of 12 years from 2001 to 2012 did var. macranthos attain an annual fruit-set ratio (an estimate of pollination success) higher than that of sympatric var. rebunense plants. These findings strongly suggest that in C. macranthos on Rebun Island, flower color results in the differential pollination success, because the pollinator prefers pale-cream Cypripedium flowers and/or avoids purple-pink ones, thereby producing pollinator-mediated selection favoring pale-cream flowers.

“…The changes in pollination environment and pollinator behavior directly affect plant mating [6,9,13]. Natural selection is believed to render the floral structure adaptive to cross-fertilization [22,23]. Orchidaceae, an advanced evolutionary family of angiosperm, has a highly specialized floral structure for insect pollination.…”

Outbreeding is usually advantageous because inbreeding suffers from depression. Nevertheless, mixed mating is very common in nature. We found two co-existing plant types, self-compatible and self-incompatible, in populations of the orchid Bulbophyllum orientale. The floral parts of this plant form a device to promote cross-pollination. Rancid substances are excreted to lure pollinators to the labellum, and pollens are attached to pollinators through a delicate mechanism. Given that many inflorescences and flowers are present on a clone and each inflorescence, respectively, pollinating insects may continuously visit inflorescences of the same clone and flowers of the same inflorescence but rarely continuously visit different populations separated by large distances. Consequently, self-compatible plants produce seeds from both crossing and selfing, and self-incompatible plants only bear crossing seeds. Thus, a crossmixed mating system is created in the population. Individuals capable of producing both crossed and selfed seeds have better chances in natural selection. The strict crossing system is broken down, and a cross-mixed mating system consisting of both mixed mating and strict crossing is formed. The cross-mixed mating system fluctuates with varying behavior of pollinating insects. The mixed mating system is favored because a population has many clone individuals and because each individual has many multi-flower inflorescences in B. orientale. The partial strict crossing is retained, and it can counteract the latent harm caused by selfing and assist in the maintenance of this cross-mixed mating system. The successful evolution of flowering plants is demonstrated by the mode of attraction for pollinating insects, the smart use of the cross-pollinating facility, and the tradeoff between crossing and mixed mating.
