Botrychium Multifidum in Pennsylvania 

 VV. L. Dix 



Botrychium multifidum (Gemel.) Rupr., ssp. typicum has 

 been found by me in two separate localities near Lake Shehaw- 

 ken in northeastern Pennsylvania. This I believe is quite a 

 southerly extension of its usual range and its only reported oc- 

 currence in Pennsylvania. Previously Herkimer County, New 

 York, over one hundred miles farther north, has been its 

 southernmost locality authoritatively reported. Both of these 

 new stations are in open pastures, one at an elevation of about 

 nineteen hundred feet above sea level, the other at sixteen hun- 

 dred feet in a thick bed of moss {Polytrichum commune). These 

 plants were collected during the last week of August, and the 

 spores were already beginning to ripen. 



Botrychium multifidum ssp. siliafolium (Presl.) Clausen was 

 found in a wooded area in rather wet soil near this last locality 

 early in August by Dr. Wherry and me. We also found at the 

 same time in the same place several plants of Botrychium sim- 

 plex var. tenebrosum (A. A. Eaton) Clausen. All these Botrych- 

 iums have been identified by Dr. Clausen. 



This locality is especially favorable for Botrychiums. In a 

 small area on an open hillside, largely in deep beds of Hairy- 

 cap Moss, grow over a thousand, by actual count and estima- 

 tion, of B. dissectum and B. obliquum. 



Within a few miles of Lake Shehawken I have collected 

 Athyrium pycnocarpon (elevation 1700 feet), Polystichum 

 Braunii (elevation 1800 feet), and Thelypteris simulata (eleva- 

 tion 2050 feet), all rare ferns for this territory. The collection of 

 these last three ferns has been reported in the American Fern 

 Journal.
