THE FERN BULLETIN 



been unavailing. The circumstances surounding the 

 Ohio record are equally elusive. According to The 

 Fern Bulletin (Vol. 5, No. 3) specimens from both 

 localities are preserved in the herbarium of Columbia 

 University and do not differ in any particular from 

 Euopean material. Mr. Harry D. Bailey of Lafayette 

 College writes me that the herbarium of that institu- 

 tion also contains specimens from both states. My 

 friend, Prof. Hopkins, in his Fern Flora of Ohio 

 (Fern Bulletin, January, 1907) states that the record 

 for that state is not authenticated by any herbarium 

 specimens. I think both records due to mixing of 

 labels, but include the species inasmuch as it will be 

 found credited to the state in Underwood's Manual 

 and elsewhere, though the circumstances are generally 

 known. 



Asplenium montanum Willd. Mountain Spleen- 

 wort. In crevices of rocks. Rare though occasionally 

 locally abundant. Lackawanna, Monroe, Carbon, 

 Chester, Lehigh. Northampton, Lancaster, York, 

 Somerset, Fayette and West and Moreland counties. 

 Forked fronds not unusual. Species rather variable 

 and sometimes fertile when half an inch high. 



Asplenium pinnatifidum Nutt. Pinnatifid Spleen- 

 wort. In crevices of shaded rocks. Rare, occasion- 

 ally locally abundant. Recorded from Philadelphia 

 and Delaware Counties in the southeast. York and 

 Lancaster along the lower Susquehanna and in Fay- 

 ette County in the southwest. Very variable. Rarely 

 laciniated specimens analogous to the laciniated form 

 of Camptosorus may be found. 



Asplenium ruta-muraria (L). Rue Spleenwort, 

 Wall-rue. On shaded limestone. Very local, and ap- 

 parently restricted to the central and eastern half of
