General research
- A study on the evolutionary history of green plants is published by Nie et al. (2020).[178]
- Description of new fossil material of Yurtusia uniformis from the Cambrian Yanjiahe Formation (China) and a study on the phylogenetic relationships and possible life cycle of this organism is published by Shang et al. (2020), who consider Y. uniformis to be a likely green microalga.[179]
- A study on the phylogenetic relationships of extant and fossil complex thalloid liverworts (Marchantiidae) is published by Flores et al. (2020).[180]
- Evidence of development of dichotomous roots in euphyllophytes that were extant during the Devonian and Carboniferous periods is presented by Hetherington, Berry & Dolan (2020), who interpret their findings as indicating that dichotomous root branching evolved in both lycophytes and euphyllophytes.[181]
- An early land plant producing multiple spore size classes is described from the Lower Devonian Campbellton Formation (Canada) by Bonacorsi et al. (2020).[182]
- A study on the impact of the appearance and evolution of herbivorous tetrapods on the evolution of land plants from the Carboniferous to the Early Triassic is published by Brocklehurst, Kammerer & Benson (2020).[183]
- A study on the production of lycopsids is published by D'Antonio & Boyce (2020), who argue that these lycopsids did not grow from sporelings into large trees through the production of a periderm cylinder, because physiological limitations would have prohibited the production of thick periderm.[184]
- A study on the architecture and development of the Carboniferous arborescent lycopsid Paralycopodites is published by DiMichele & Bateman (2020).[185]
- New information on the anatomy of Weichselia reticulata is presented by Blanco‐Moreno, Decombeix & Prestianni (2020).[186]
- A study on the phylogenetic placement of the extinct fern genus Coniopteris is published by Li et al. (2020).[187]
- New information on the morphology of Paleoazolla patagonica is presented by Benedetti et al. (2020), who evaluate the implications of this taxon for the knowledge of the evolution of water ferns.[188]
- A study aiming to determine which ferns were most likely to be the producers of Cyathidites spores from earliest Paleocene plant localities across western North America, and were most likely to be among the first plants in western North America to thrive in the immediate aftermath of the Cretaceous–Paleogene extinction event, is published by Berry (2020).[189]
- A study on the morphology and development of Genomosperma, and on its implications for the knowledge of the evolutionary origins of seed development, is published by Meade, Plackett & Hilton (2020).[190]
- A pollen organ resembling seed fern pollen organs Dictyothalamus and Melissiotheca is described from the Lopingian Umm Irna Formation (Jordan) by Zavialova et al. (2020), who interpret this finding as evidence of persistence of lyginopterid seed ferns until the late Permian.[191]
- Evidence of increasing atmospheric CO2 concentration at the onset of the end-Triassic extinction event, based on data from fossil leaves of the seed fern Lepidopteris ottonis from southern Sweden, is presented by Slodownik, Vajda & Steinthorsdottir (2020), who confirm L. ottonis as a valid proxy for pCO2 reconstructions.[192]
- A study on the anatomy of the seed cone scales of Krassiloviaceae within the order Voltziales.[193]
- A study on the microscopic wood anatomy of a fossil tree trunk of Agathoxylon arizonicum with the characteristic external features of a fire scar from the Upper Triassic Chinle Formation (Petrified Forest National Park, Arizona, United States) is published by Byers et al. (2020), who evaluate the implications of this specimen for the knowledge of the evolution of fire-adapted plant traits.[194]
- A putative bamboo "Chusquea" oxyphylla from the early Eocene Laguna del Hunco biota (Argentina) is reinterpreted as a conifer by Wilf (2020), who transfers this species to the genus Retrophyllum.[195]
- A study on evolutionary history of conifers as indicated by fossil and molecular data, aiming to determine whether the rise of angiosperms drove the decline of conifers and other gymnosperms, is published by Condamine et al. (2020).[196]

- Fossil pollen of flowering plants is reported from the Aptian and Albian of Australia by Korasidis & Wagstaff (2020), who evaluate the implications of their findings for the knowledge of the timing of the appearance and diversification of the flowering plants in the high-latitude southern basins of Australia.[198]
- A study on the morphology of palm and palm-like pollen from the Eocene Yaw Formation (Myanmar), and on the implications of these fossils for the knowledge of distribution and diversity of Eocene palms across the globe, is published by Huang et al. (2020).[199]
- Fossils fruits of Illigera eocenica, representing the second fossil occurrence of Illigera worldwide and the first in Asia, are described from the Eocene Niubao Formation (central Tibetan Plateau) by Wang et al. (2020), who evaluate the implications of this finding for the knowledge of the climate in the central Tibetan Plateau during the early middle Eocene, and for the knowledge of the floristic links between Asia and North America during the Paleogene.[200]

- Evidence from Bangong-Nujiang suture indicating that the Tibetan Plateau area hosted a diverse subtropical ecosystem approximately 47 million years ago and that this area was both low and humid at the time is presented by Su et al. (2020), who also report that the composition of this flora is similar to Early-Middle Eocene floras in both North America and Europe, but shows little affinity to Eocene floras from the Indian Plate.[207]
- A study aiming to estimate leaf dry mass per area in fossil plants from 22 western North American sites spanning the Eocene–Oligocene transition is published online by Butrim & Royer (2020), who evaluate the implications of their findings for the knowledge of the impact of the environmental changes occurring during the Eocene–Oligocene transition on leaf‐economic strategies of plants.[208]
