    Consensus regarding arborescent lycopsid gross anatomy has not been reached in 150 years of study (Williamson, 1872; Walton, 1935; Pannell, 1942; Felix, 1952; Andrews & Murdy, 1958; Eggert, 1961; Bateman, 1994; Krings et al., 2011; Boyce & DiMichele, 2016; Hetherington et al., 2016; D'Antonio & Boyce, 2020; D'Antonio et al., 2020; DiMichele & Bateman, 2020). By comparison, the idea that they did not produce secondary phloem originated in the mid-19th century (Williamson, 1872).

  • Arborescent lycopsid periderm production was limited. The New phytologist D'Antonio, M. P., Boyce, C. K. 2020


    Late Paleozoic arborescent lycopsids have been thought to have grown from sporelings into large trees through the production of a periderm cylinder, particularly massive in the proximal portion of the trunk and tapering distally, with this rind of bark providing most of their structural support. Here, we argue that physiological limitations would have prohibited the production of thick periderm and test this hypothesis using multiple independent lines of evidence derived from anatomical permineralization and surface impression fossils that allow both direct and indirect measurement of periderm radial thickness. Across all six genera of Pennsylvanian arborescent lycopsids that were investigated, all evidence indicates limited periderm production: typically less than 5 cm, always less than 15 cm, even in trunks that would have reached a meter or more in diameter. The large amount of arborescent lycopsid periderm in Middle Pennsylvanian coals represents taphonomic enrichment rather than a true anatomical signal, complicating interpretation of their biology including biomechanics and early ontogeny.
