THE FERN BULLETIN 



f. superbissima but should probably be named N. ex- 

 alt at a f. muscosa. Still another form has been named 

 veridissima in allusion to its dark green color. Inci- 

 dentally the name itself more than alludes to the ig- 

 norance of the namer in regard to the Latin word for 

 green. Nephrodiitm Giatrasi is another sport hitherto 

 uncatalogued. The inordinate multiplication of forms 

 in this one species must already make British form 

 makers tremble for their laurels. What is a mere 

 three hundred forms of Scolopcndrium or five hun- 

 dred of the lady fern, to what we can produce if we 

 try. Exaltata is a fine specific name; just the thing to 

 exalt this side of fern growing. All we need is time.
