I.—Woodwardian Museum Notes. On Calamites undulatus (Sternb.)

  • Albert C. Seward (a1)


At the end of his monograph on the structure of Calamites, Prof. Williamson makes the following remark: —“I am disposed to regard all existing specific names and definitions as worthless. They separate things that I believe to be identical, and confound others that are obviously distinct.” The specimen described below affords an interesting example in support of this view.
