“…Unlike heterostyly and enantiostyly, this polymorphism does not involve pollen segregation on pollinators' bodies to achieve intermorph pollination. Remarkably, the stylar movements of the morphs tend to be synchronous and correlated with the foraging behaviour of floral visitors, mostly large-bodied bees, particularly Xylocopa (Zhang et al 2003;Takano et al 2005). The floral morphs in flexistylous populations are reported to occur in equal frequencies but extensive surveys have yet to be undertaken and the inheritance of the polymorphism is unknown.…”

Charles Darwin studied floral biology for over 40 years and wrote three major books on plant reproduction. These works have provided the conceptual foundation for understanding floral adaptations that promote cross-fertilization and the mechanisms responsible for evolutionary transitions in reproductive systems. Many of Darwin's insights, gained from careful observations and experiments on diverse angiosperm species, remain remarkably durable today and have stimulated much current research on floral function and the evolution of mating systems. Here I review Darwin's seminal contributions to reproductive biology and provide an overview of the current status of research on several of the main topics to which he devoted considerable effort, including the consequences to fitness of cross-versus self-fertilization, the evolution and function of stylar polymorphisms, the adaptive significance of heteranthery, the origins of dioecy and related gender polymorphisms, and the transition from animal pollination to wind pollination. Post-Darwinian perspectives on floral function now recognize the importance of pollen dispersal and male outcrossed siring success in shaping floral adaptation. This has helped to link work on pollination biology and mating systems, two subfields of reproductive biology that remained largely isolated during much of the twentieth century despite Darwin's efforts towards integration.

An overview of the floral biology including floral odour analyses of twenty‐two Bornean Scaphochlamys taxa and three ex Bornean Scaphochlamys taxa was undertaken. All Scaphochlamys species investigated bloom diurnally. Pollen is released gradually, either simultaneously with stigma secretion or later (mostly within one hour). Flowers of most Scaphochlamys species were found to emit a mild odour but a few are odourless. Stigmas and anther spurs (where present) differ among the taxa investigated. Natural fruit set percentages of all species investigated were very low, up to 14.29%. Scaphochlamys species are facultatively xenogamic as the pollen/ovule ratios (P/O ratios) were high. Analysis of floral odour revealed 102 identifiable floral volatile organic compounds (VOCs), representing 31.8% of the compounds found. The volatile fraction was characterized by the aliphatics class (21.5%), monoterpenes (3.4%), irregular terpenes (0.3%) and benzenoids and phenyl propanoids (0.6%). Two pollinator guilds were found: halictid bees and Amegilla bees.

Flexistyly in Plagiostachys was first reported by Takano et al., while they provided no detailed study on pollination biology and breeding system. In this study, we tested this suspicion in one species of Plagiostachys (Plagiostachys austrosinensis). Field observations suggested that flexistyly was present in this species, and stigmatic behavior was similar to that reported for Alpinia and Amomum species. Two phenotypes (anaflexistylous and cataflexistylous) occurred in a ratio of 1:1 in natural populations. Anthesis began around 1530–1600 h and lasted for about 24 h. Pollen viability and stigma receptivity remained high throughout the flowering process. Mean nectar volume (4.15–11.30 μL) and mean sugar concentration (>32%) also remained at a high level during the flowering process. No fruit set occurred in unpollinated bagged plants. Two pollinators (Bombus pyrosoma and Vespidae spp.) and one pollen robber (Mutillidae spp.) were found as flower visitors. Fruit set following self‐pollination and cross‐pollination did not differ significantly in the cataflexistylous morph. Partial self‐incompatibility was apparent in the anaflexistylous morph. These results provide the concrete evidence of flexistyly in Plagiostachys and a more thorough understanding of its evolutionary origin in gingers.
