BOOK NEWS. 



Prof. John H. Schaffner has recently published 

 "The Pteridophytts of Ohio" in the "Proceedings of 

 the Ohio State Academy of Science." It is a neat 

 little booklet of forty pages, containing several pages 

 of introductory matte-, a list of species with descrip- 

 tions and their ranges in Ohio, and a good glossary. 

 The nomenclature is that of the "American code" and 

 the key to the genera is based in part upon the vascular 

 bundles. Their latter while quite accurate is likely to 

 be puzzling to the average individual who attempts to 

 use it. The ferns are not so numerous, however, as to 

 make this a serious difficulty. Forty-three ferns and 

 eighteen allies are listed. The thoroughly scientific 

 treatment must make the list of great aid in further 

 studies of the Ohio pteridophytes. 



That part of the "North American Flora" which 

 begins the ferns (Vol. 16, part 1) was issued Nov. 6, 

 1909 and is a volume of considerable interest to all 

 who follow the evolution of fern study. It is not hard 

 to glean from this work the fact that the nomenclature 

 of ferns moves in cycles and has returned to a sem- 

 blance of that in use ten years ago. It is something of 

 a surprise being fairly described as conservative. Un- 

 derwood's Ornithopteris has been abandoned for the 

 well-known Anemia that most of us have continued to 

 use and under Osmunda we find O. regalis standing for 

 the royal fern instead of the proposed O. spectabilxs.
