[1230] In a footnote to Fontaine’s description of Jurassic plants of Oregon, Lester Ward writes:—“Seward treats Sagenopteris as a fern, classing it now (Jur. Fl. Yorkshire Coast, 1900, p. 161) in the family Polypodiaceae, although in his Wealden Flora, 1894, p. 129, he placed it in the Schizaeaceae.” [Ward (05) p. 83, note b.] My words are “I am disposed to regard Sagenopteris as probably a genus of ferns” (loc. cit. 1900, p. 161). I have never referred this plant to the Polypodiaceae or Schizaeaceae or to any other family.
