THE SUPPOSED FOSSIL OPHIOGLOSSUM 



T. D. A. C0CK.ERELL 



In ToRREVA, vol. 24, p. 10, I described a supposed fossil 

 Ophioglossum from the Eocene of Wyoming, naming it 0. has- 

 tatijorme. The specific name had reference to the resemblance 

 to a spear-head, not to the conventional term hastate. In 

 ToRREYA of the same year, p. 49, Dr. E. W. Berry stated that 

 the plant was by no means an Ophioglossum, but was in fact a 

 Danaea, belonging to the species D. coloradensis Knowlton, 

 described from the Green River shales of Colorado. This led 

 to a lengthy correspondence with Dr. Knowlton, Dr. W. R. 

 Maxon and Dr. Marshall A. Howe, out of which certain results 

 have emerged, showing that the whole matter needs reconsider- 

 ation. The facts and probabilities are as follows: 

 (i) The fossil is assuredly not an Ophioglossum. 



(2) Still less is it a Danaea. Dr. Maxon kindly loaned me ex- 



cellent Danaea material for comparison. 



(3) The fragment described by Knowlton (1923) as Danaea 



coloradensis is apparently a different thing, and in the 

 absence of proof to the contrary, is to be retained in 

 Danaea. I have not seen it.
