International Journal of Molecular Sciences, 2023 Asexual lineages are perceived to be short-lived on evolutionary timescales. Hence, reports for exceptional cases of putative ‘ancient asexuals’ usually raise questions about the persistence of such species.

BMC Biology, 2022 Background Eudicots are the most diverse group of flowering plants that compromise five well-defined lineages: core eudicots, Ranunculales, Proteales, Trochodendrales, and Buxales.

Phylogeography of a Tertiary relict plant, Meconopsis cambrica (Papaveraceae), implies the existence of northern refugia for a temperate herb [PDF]
, 2011 The perennial herb Meconopsis cambrica, a western European endemic, is the only European species of the otherwise Himalayan genus Meconopsis and has been interpreted as a Tertiary relict species.

Evolution of Perianth and Stamen Characteristics with Respect to Floral Symmetry in Ranunculales [PDF]
Annals of Botany, 2007 Floral symmetry presents two main states in angiosperms, namely polysymmetry and monosymmetry. Monosymmetry is thought to have evolved several times independently from polysymmetry, possibly in co-adaptation with specialized pollinators. Monosymmetry commonly refers to the perianth, even though associated androecium modifications have been reported ...

An Angiosperm species dataset reveals relationships between seed size and two-dimensional shape [PDF]
, 2019 Datasets containing information on seed size have been published and are currently available. Nevertheless, there is a lack in the literature of a dataset dedicated to seed shape. We present a preliminary version for a dataset on seed morphology based on

Acta Palaeobotanica, 2018 Floral and fruit morphology of the early eudicot Ranunculaecarpus quinquecarpellatus Samyl. is described based on details from sectioning and microscopy of the permineralized type material from the Albian Buor-Kemyus Formation of the Zyryanka coal basin.

Tinkering with transcription factor networks for developmental robustness of Ranunculales flowers [PDF]
Annals of Botany, 2016 The flowers of core eudicots and monocots are generally determined by the number of floral organs they produce, and their developmental set-up tolerates little change from the bauplan once the floral primordium is initiated. Many species outside the core eudicots and monocots are more plastic in the number of floral organs they produce.

Plants, 2023 Fossils of plant–insect interactions are direct evidence of paleoecological relationships between these two dominant groups in terrestrial ecosystems. We present a variety of plant–insect interactions from the late Early Cretaceous (latest Albian) in the
