as I have heard them call this the "rick-rack fyorn," in allusion 

 to the outlines of the fertile fronds. 



Asplenium ebenoides R. R. Scott. A few specimens of this 

 have been found in Marion county, near Salt Lick creek, sur- 

 rounded by ebony spleenwort and the walking fern. 



Asplenium parvulum Mart. & Gal. Little Ebony Spleen- 

 wort. This is not uncommon in Warren county, growing in 

 limestone soil. My first specimens were found in a sink-hole 

 in a fox's den. This species does not seem to have been men- 

 tioned in other lists of Kentucky ferns. 



Asplenium pinnatifidum Nutt. Pinnatifid Spleenwort. Fre- 

 quent, but extremely local in Southern Kentucky, growing only 

 on sandstone cliffs. In one locality in Warren county there was 

 an unusual form of this species, the lower pinnae being prolonged 

 to a great length. Dr. Underwood, to whom I sent specimens, 

 considered it quite unique and unusual. Unfortunately I had 

 a visiting entomologist with me, whom the Society for the Pre- 

 servation of Native Plants should convert, for she gathered all 

 the peculiar fronds. Though I have visited this same spot sev- 

 eral times since, I have never seen this form again. 



Asplenium ruta-muraria L. Wall rue. Rare. Found mostly 

 in eastern Kentucky. 



Asplenium montanum Willd. Common and widely distributed. 

 I have found it on many sandstone cliffs of Edmonson county, 

 though not abundant in Warren county. It seems to fork more 

 frequently than any of our other ferns. I have found single 

 plants with all the fronds forked two or three times. 



Asplenium trichomanes L. Maidenhair Spleenwort. Not 

 uncommon throughout the State. 



Athyrium thelypteroides Desv. Silvery Spleenwort. Com- 

 mon throughout the State in rich, moist soil. It is especially 

 fine in Muhlenburg county, near Rockport. 



Athyrium fHix-foeminy Roth, Lady Fern. Common in sandy 

 soil. Variable.
