The fossils were part of approximately 20,000 specimens collected from 1942 to 1989 by Thomas Bones, A. W. Hancock, R. A. Scott, Steven R. Manchester, and a number of high school students. The Diploporus specimens were studied by paleobotanist Steven R. Manchester of the University of Florida. He published his 1994 type description for Diploporus torreyoides in the journal Palaeontographica Americana  In his type description Manchester noted the generic name is derived from the Greek diplo meaning "twofold" and poros meaning "passage" in reference to the paired vascular scars. The specific epithet torreyoides, reflects the similarities between Diploporus and the living genus Torreya. Description The seeds of Diploporus are subovoid and bilaterally symmetrical with a slightly pointed tip and round base. The seeds have an overall length raging between  and a width between . There is a sharp crest along the upper third of the seed that is formed by the dorsal and ventral faces. As with other Taxacaeae genera Diploporus has a pair of vascular scars on sides, located at the widest point. The seeds are identified from Taxus and Torreya species by several features of the exterior morphology. The overall shape of the base is not as pointed as that of Torreya but not as truncate as the base of Taxus and in size, Diploporus seeds are larger than Taxus seeds, but smaller than Torreya.
