Pseudobornia is a genus of plants known only from fossils found from the Upper Devonian.[1] It contains a single species Pseudobornia ursina, and is the earliest fossil assigned with certainty to the Sphenopsida.

The first fossils of Pseudobornia were collected by Johan Gunnar Andersson on Bear Island in the 1890s.[2] Hans-Joachim Schweitzer, a paleobotanist, was the first to interpret the fossils as belonging to a large tree, based on additional fossils discovered in Alaska in the 1960s.[3][4]
