American Fern Journal 61 



(Muhl.) D. C. Eaton is the most abundant fern of the 

 deep woods. Above 1,200 feet elevation on the hilltops 

 and mountain sides there is abundance of the very- 

 broad variety dilatatum (Hoffm.) Gray, forma an a de- 

 nium Robinson. Nothing in the so-called "Canadian 

 forest" is more beautiful than a mountain glade filled 

 with this large but delicate fern. 



Roth species of Cystopteris are present, but they are 

 not widely distributed. Woodsia ilvensis (L.) R. Br. 

 is abundant on dry ledges in Strong, Wilton, and Chest- 

 erville, perhaps elsewhere. Dicksonia and Onoclea sen- 

 sibilis L. are our two most common species in dry and 

 moist soil. The latter, when cut with the grass in 

 July, frequently develops later an anomalous frond 

 which is best described as variety obtusilobata (Schkuhr) 

 Torr. It is only a seasonal form. All along the inter- 

 vales, and frequently on moist uplands, this species 

 flourishes, and repeated frosts seem to have no effect on 

 its roots. O. Struth i opteris (L.) Hoffm. is everywhere 

 in the alluvium along the Sandy River, and occasion- 

 ally on the higher land. 



Of the Osnumdarrae, all three species are abundant, 

 but Osmxnda cinnamomea L. is the most flourishing. 

 Variety frondosa Gray and var. incisa, J. W. Hunting- 

 ton, have been detected by Mr. Jewell, but they are 



very far from common. 



Ophioglossum vvlgatum L. I have found several times, 

 usually in drvish soil. It seems to like the shade of 

 Pteris, and it is probably not rare, but it is so slender 

 that it is frequently overlooked. 



The other genus of this order, Bolrychium, is well 

 represented, both by species and by individuals. The 

 little moonwort with the long name, B. lanceolatuni 

 (Gmel.) Angstroem, var. angustisegmentum Pease & 

 Moore is the rarest one, and I have found it in only 

 three places in wet woods. B. ramosum (Roth) Aschers
