THE FERN BULLETIN 



though it will never be recorded as common. We give 

 as a frontispiece, a photograph of the plant made from 

 living specimens in the Bruce Peninsula by Prof. A. B. 

 Klugh. Here it is seen associated with the herb Robert 

 and other shade plants, much as one would expect to 

 find it. 



THE FERN FLORA OF INDIANA. 



By F. C. Greene. 



Several papers containing lists of the Pteridophytes 

 of Indiana have been published. The latest of these is 

 that of Prof. Stanley Coulter published in 1900. Since 

 that time species new to the State have been found and 

 more data regarding the distribution has been gather- 

 ed. These facts seem to warrant the publication of a 

 revised list bringing together the accumulated data. 

 While the following list is not complete either with re- 

 gard to number of species found within the State or 

 their distribution, particularly the latter, it is believed 

 the climate and topography will not permit the dis- 

 covery of many additional species of ferns. In the more 

 difficult group, the fern allies, it is probable that many 

 other discoveries will be made. 



The State of Indiana is included between 37°41' and 

 41°46' north latitude, and between 84°44' and 88°6' 

 w T est longitude. It is bounded on the north 

 by the parallel which is ten miles north of the 

 southern extremity of Lake Michigan ; on the east by 

 the meridian of the mouth of the Great Miami River; 

 on the south by the Ohio, and on the west by the War 

 bash River and the meridian of Vincennes. Its ex- 

 treme length is 250 miles, its average width 145 miles, 

 its area 36,350 square miles." (Indiana Geography by 

 Chas. R. Dryer.)
