PTERIDOGRAPHIA 



Additional Dorset Ferns. — I have two additions to 

 make to my list of Dorset (Vt.) ferns: Botrychium sim- 

 plex, and Pellaea atro purpurea, both of which I had the 

 pleasure of finding last summer. It is a curious fact 

 that one may go to the same spot, year after year, in 

 search of the same fern and yet fail, year after year, to 

 find it. But my persistence has been rewarded in this 

 instance. My list now numbers fifty-five species and 

 , varieties from this locality. — Mrs. Emily Hitchcock 

 Terry, Northampton, Mass. 



Three Fertile Panicles. — Mr. H. E. Ransier, Man- 

 lius. X. Y., sends us an excellent photograph of a plant 

 of the dissected form of the grape fern (Botrychium 

 tcrnatum) possessing three fertile panicles. Such speci- 

 mens are usually the result of unusual vigor in the plant, 

 and this one is of especial interest from the fact that it 

 is the dissected form which we are often assured, incor- 

 rectly, does not grow far from the sea-coast.
