Crested ]Margixal Fern 

 Aspidhim cristcdinn X marginale 



Both the crested fern and CHnton"s fern appear to 

 hybridize with the marginal shield fern -n-ith the result 

 that the upper part of the frond is like marginale and the 

 lower like cristatum, including the veining and texture. 



This form was discovered by Raynal Dodge, verified 

 by Margaret Slosson and described by Geo. E. Daven- 

 port, who had a small colony under cult i^'at ion in his fern 

 garden at ^Medford, Mass., and to him the writer and other 

 friends are indebted for specimens. 



Found occasionally throughout New England and 

 New Jersey. Other supposed hyfirids have been found 

 between the marginal shield and the spinulose fern and 

 its variety inicrmaUum, and with Goldie's fern; also 

 between the crested fern, including Clinton's variety and 

 each of the others mentioned; and, in fact, l)etween almost 

 all pairs of .species of the wood ferns, although we do not 

 think they have been positively ^•erified. Still other 

 .species of ferns are known to hybridize more or less, a.s we 

 saw in the case of Scott's spleenwort.
