40 ASPLENIUM 



SCOTT'S SPLEEN WORT: 



Asplenium ehenoides. 



Fronds 4 to 8 inches high, lance-shaped, pinnat- 

 ifid or pinnate below, deeply pinnatifid above, di- 

 visions broadest at the base, with considerable 

 variation in their shape and cutting; apex usually- 

 long and slender, often producing young fronds at 

 the tip; stipes dark and shining. Demonstrated 

 by Miss Margaret Slosson to be a hybrid between 

 the walking fern and the ebony spleenwort. 



Fruit dots as in other spleenworts. 



Found on limestone cliffs from Vermont to Mis- 

 souri, and southward; very rare.
