• 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.{{Cite journal |last1=Gentis |first1=N. |last2=Licht |first2=A. |last3=Boura |first3=A. |last4=De Franceschi |first4=D. |author5=Zaw Win |author6=Day Wa Aung |last7=Dupont-Nivet |first7=G. |year=2022 |title=Fossil wood from the lower Miocene of Myanmar (Natma Formation): palaeoenvironmental and biogeographic implications |journal=Geodiversitas |volume=44 |issue=28 |pages=853–909 |doi=10.5252/geodiversitas2022v44a28 |s2cid=252748599 |url=https://sciencepress.mnhn.fr/en/periodiques/geodiversitas/44/28 |doi-access=free }}
• 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.{{Cite journal|last1=Wilf |first1=P. |last2=Zou |first2=X. |last3=Donovan |first3=M.

• 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).{{cite journal|last=Pole |first=M |title=A vanished ecosystem: Sophora microphylla (Kōwhai) dominated forest recorded in mid-late Holocene rock shelters in Central Otago, New Zealand |year=2022 |journal=Palaeontologia Electronica |volume=25 |issue=1 |pages=Article number 25.1.1A |doi=10.26879/1169 |doi-access=free }}
