along the midrib : pinnules set at a slight angle to the 

 midrib and like the pinnae opposite below and alternate 

 above, about 24 pairs on the largest pinnae ; segments 

 very regular, about the same length for two-thirds of the 

 pinnule and lacking the greater or less enlargement of 

 lowest anterior segment usually characteristic of varie- 

 ties of fUix-fccmina, broad-ended with 4 teeth at end. 

 1 tooth on inner edge and 2 or 3 on outer edge, each 

 pinnule presenting very much the appearance of a double- 

 edged comb : sori small and rather sparse ; texture very 

 thin. 



Since receiving Dr. Waters' specimen I have had the 

 good luck to discover the same variety near my own 

 home at Clayville. Xew York. It is about three-quarters 

 the size of his and shows one sorus on each of about one- 

 half the segments, situated on the lowest anterior veinlet 

 and always hamate. 



OSMUXDA CIXXAMOMEA F. IXCISA.. HuXTIXGTOX. This 



fern seems to have been first mentioned by Mr. Hunting- 

 ton in The Ferx Bulletin for January. 1899. I had 

 never seen any specimens of it excepting his until the 

 spring of 1904. toward the end of our long dry spell of 

 weather. I was walking through one of our home 

 swamps dry shod, when I ran right into a large clump 

 of O. cinnatnomea incisa. It was a peculiar looking 

 plant, especially as some of the fronds were normal, 

 while others were deeply and irregularly incised. Only 

 the upper halves of the fronds were cut, the lower halves 

 being entirely normal. The incisions were very unequal, 

 some pinnae being quite regularly and deeply toothed, 

 while others had two or three large projections from 

 each side of the pinnule. Other pinnules on the same 

 pinna are perfectly straight-edged, so that these fronds 

 present a ragged, irregular appearance. The swamp 

 where they occur is at present an open one. but 12 

 or 15 years ago it was wooded, and a small portion 

 of it still remains so. In this wooded area I have found 

 very peculiar and freakish forms of Xcphrodium spin- 

 ulosum, so I may be permitted to doubt that the cutting
