New and Notable Members of the Indiana Flora. 



E. J. Grimes. 



The following notes deal with the distribution and the ecological 

 condition of the species mentioned. They pertain for the most part to 

 the flora of Pntnam County. 



The determinations have been verified by authorities, and the speci- 

 mens are deposited in the National Herb., Gray Herb., and my herbarium. 



The nomenclature follows the Vienna Code as exemplified in the 

 seventh edition of Gray's Manual. 



The seventeen species and varieties that are recorded as new to the 

 Indiana flora are marked with an asterisk (*). 

 Ophioglossum vulgatnm L. 



Putnam County. Four miles south of Russellville a large colony of 

 this plant was found June 4, 1911, on a wooded hillside along Raccoon 

 Creek. 



The plants were very thrifty, from 24 to 32 em. in height, the leaves 

 3.5-4 cm. wide, and 6-7 cm. long. The sterile regments were attached 

 below the middle. 



Woodsia obtusa (Spreng.) Torr. 



Putnam County. Grows sparingly on sandstone ledges. September 

 4, 1911. 



Aspidium noveboracense (L.) SW. 



Parke County. Low woods in moist soil. Small colony was found 

 one mile north of Ferndale, September 11, 1910. 

 Asplenium Thrichomanes L. 



Putnam, I'arke and ^Montgomery counties. Frequent on dry sandstone 

 ledges, found with Polyodiutn rulgare. 

 *Marsilea quadrifolia L. 



Putnam County, south of the Vandalia station at Greencastle in an 

 old pond. Tills species is quite abundant on one side of the ix»nd, but 

 is rapidly disappearing, due to the draining of tlie pond and the subse- 

 quent encroaching of the vegetation, which is filling up the pond and 

 eventually choking out the IMarsilea. This plant was first detected by 

 Dr. Banker of De Pauw Univer.sity in 1904. Possibly introduced by some 

 botanist.
