Abstract: The conifer family Cupressaceae encompasses seven subfamilies. Five of them were once considered to constitute the family Taxodiaceae, later eliminated because of its paraphyletic nature but remaining as an informal category for early‐diverging Cupressaceae lineages. Among the taxodiaceous subfamilies, Athrotaxoideae shows a unique morphology in its ovuliferous complexes (OCs) and a phylogenetically unexplored fossil record. We describe the new genus and species Patagotaxodia lefipanensis, based on OC adpressi… Show more

“…Furthermore, all reproductive organs in gymnosperms (fossil and extant) are never known to have more than two layers of papery lateral appendages overlapping each other as in Archaebuda ( Figure 3 a,b). These differences distinguish our fossil from Bennettitales, Ginkgoales, Pentoxylales, Corystopsermales, Peltaspermales, and Gnetales [ 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. Therefore, these gymnosperm groups are not further considered.…”

“…The scaly leaves on the stalk of Archaebuda are adnate to the stalk for most of their length, with triangular pointed tips ( Figure 2 d–f). Among known gymnosperms, scaly leaves of similar morphology are frequently seen in conifers, but so far have never been seen in Bennettitales, Ginkgoales, and Gnetales [ 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. Although cataphylls similar to scaly leaves in Archaebuda are seen in the bottom of some cycad cones, these cataphylls have distal pricks that are lacking in the scaly leaves of Archaebuda ( Figure 2 d–f), and numerous peltate shields or tapering segments of “sporophylls” on the surface of cycad cones [ 55 , 56 , 57 , 58 , 59 ] distinguish cycads from Archaebuda ( Figure 2 a–c).…”
