form of this species or at least a crested form resem- 

 bling it, by crossing it with crested forms of Poly- 

 stichum angulare but without success. Now he has 

 found a wild plant with the desired characteristic and 

 expects soon to have plenty of the new form since 

 sporelings are likely to repeat the aberrations of their 

 parents and the plants found were in full fruit. With 

 the exception of the tips, the fronds are quite like those 

 of normal specimens. At the tip, however, the midrib 

 divides again and again forming a compact little tuft.

 the plant is better handled in literature if given a name 

 it would be well to christen it Polystichurn acrosti- 

 choides f. cristatum. 



Fern Flora of Indiana. — Since the publication of 

 "The Fern Flora of Indiana" in the October 1911 num- 

 ber of this magazine, E. J. Grimes has reported one 

 species new to the state list and recorded several ad- 

 ditional stations for species previously known to grow 

 in the state. Ophioglossum viilgatum previously 

 known only from the southern part of the state and 

 from one station in the extreme northwest, is recorded 

 from Putnam county, near the center. In the same 

 county Woodsia obtusa is said to grow sparingly on 

 sandstone ledges. Asplenium trichomanes is also re- 

 ported from this county as well as from Parke and 

 Montgomery counties all these being new stations. 

 Nephr odium noifcboracense, apparently nowhere 

 abundant in the state is reported from Parke county. 

 The species new to the state is Marsilia quadrifolia. 

 This was found "South of the Vandalia station at 

 Greencastle in an old pond." The species is reported as 

 being abundant on one side of the pond, though
