Conifer research

• Bodnar et al. (2022) reassess the anatomy and systematics of the permineralized conifer-like woods from the Triassic strata from Argentina, confirm the assignment of the logs related to the families Cupressaceae and Cheirolepidiaceae, as well as three taxa related to Araucariaceae (Agathoxylon cozzoi, Agathoxylon protoaraucana and Agathoxylon argentinum), and argue that the fossil woods previously assigned to the families Podocarpaceae and Taxaceae do not have enough preserved characters to support such assignment.^[65]
• A study on the pattern of conifer turnover across the Cretaceous-Paleogene boundary in the Raton and Denver basins (Colorado, United States) is published by Berry (2022).^[66]

Monocot research

• Leaf fossils of costapalmate-palms belonging to the genus Sabalites are described from the ?Santonian–Campanian Belly River Group, Campanian Foremost Formation (Alberta, Canada) and Maastrichtian Frenchman Formation (Saskatchewan, Canada) by Greenwood, Conran & West (2022), who interpret the studied fossils as constraining climate reconstructions for the Late Cretaceous high mid-latitudes of North America (c. 55° N) to exclude significant freezing episodes; the authors also transfer the Late Cretaceous species "Geonomites" imperialis to the genus Phoenicites, and reassess Sabalites carolinensis as more likely to be Campanian than Coniacian–Santonian in age.^[79]

• New Oligocene flora is described from the Dong Ho Formation (Vietnam) by Huang et al. (2022), who interpret the studied fossils as evidence of long-term environmental, floristic and vegetational stability in this region since the Paleogene.^[199]
• Gentis et al. (2022) describe fossil wood specimens from the Miocene Natma Formation (Myanmar), representing an assemblage dominated by members of the families Fabaceae and Dipterocarpaceae, interpreted as coming from different types of low altitude forest ecosystems (tropical wet evergreen, tropical dry and deciduous, and tropical littoral), and interpreted as indicative of a monsoonal climate with an alternance of a dry season and a wet season.^[200]
• Abundant compression floras dominated by angiosperm leaves are described from two sites of probable Pliocene age in Brunei by Wilf et al. (2022), who interpret these floras as evidence of dipterocarp-dominated lowland rainforests in the Malay Archipelago before the Pleistocene.^[201]
• A study on the impact of the extinct Neotropical megafauna on the variability in plant functional traits and biome geography in Central and South America is published by Dantas & Pausas (2022).^[202]
• A study on plant material from rock overhangs from mid-late Holocene sites along the Kawarau-Cromwell-Roxburgh Gorges in Central Otago (New Zealand), much of which was likely transported as roosting material or consumed by moa birds, and on its implications for the knowledge of the mid-late Holocene regional vegetation of Central Otago and the knowledge of vegetation changes since mid-late Holocene, is published by Pole (2022).^[203]
• A study on the role of hydraulic failure in the evolution of early vascular plants is published by Bouda et al. (2022), suggesting that drought selection played a key role in the diversification of vascular arrangements beginning with the Devonian explosion.^[204]
