Not illustrated. 1874 Excerpt: ...sent to him, he writes that he thinks it belongs more properly to the same group as Archseoptcris Halliana (=: Sphenopteris laxa, llall), to which I had from the first supposed it to be related. Prof. Lesquerenx, to whom I showed the specimens, also supposed the species to belong to Paleeopleris of Schimper, which is the same as Archseopleris, Dawson, the name Paleeopleris being preoccupied. Some other high authorities on fossil botany, however, have arranged similar forms under the names Asplenites and Adianlites. From these remarks the student will readily understand that in the present unsettled state of opinion in regard to the limits between several of these older groups of fossil ferns, and the consequent confusion existing in their nomenclature, it is impossible to determine beyond doubt under what genns this species may ultimately have to be ranged, when all of these questions can be settled. It may therefore have to take the name Sphenopteris Lescuriana, or Adiantites Asplenites) Lescurianus. Or, possibly, in case the name Paleeopleris of Genitz should he found not to have been based upon a tenable genus, so that Schimper's name Palseopteris would have to replace Archeeopteris, our species may have to be called Palseopteris Lescuriana. Specifically this form will be readily distinguished from Cyc/. Archseopleris) Halliana, by wanting the row of broad separate pinnules along its rachis between the pinnae as seen in that species, as well as by its more divided inner pinnules and more rigid pinnae. Prof. Dawson thinks it more nearly related to his C. Palseopteris) Rogersi, though, on comparison, he says he finds that the Rogersi has larger pinnse, and more obtuse as well as larger pinnules, and a somewhat different venation.
