Floral characters and species diversification
WebJun 28, 2024 · When the habitat occupied by a specialist species is patchily distributed, limited gene flow between the fragmented populations may allow population differentiation and eventual speciation. ‘Sky islands’—montane habitats that form terrestrial islands—have been shown to promote diversification in many taxa through this mechanism. We … WebIn flowering plants, the ambiguity of associations between traits and diversification has sparked debate since Darwin’s description of angiosperm diversification as an ‘abominable mystery’. Recent work …

WebThe petals of many representatives during anthesis form a closed pollination chamber. Protogynous dichogamy with strong scent emissions especially during the pistillate stage is a character of nearly all species. Scent emissions can be enhanced by thermogenesis. The prevailing reproductive system in the family seems to be self-compatibility.
