  • 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]

  • A study on the production of periderm in Late Paleozoic arborescent 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 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 Krassilovia mongolica is published by Herrera et al. (2020), who argue that K. mongolica and Podozamites harrisii are the seed cones and leaves of the same extinct plant, and name a new family Krassiloviaceae within the order Voltziales.[193]

  • 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]
  • Presence of secretory tissues is reported in extinct flowers from the Cretaceous amber from Myanmar and Cenozoic Dominican amber (including specimens preserved while in the process of emitting compounds) by Poinar & Poinar (2020).[197]

  • 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 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]
