plants at their ends. Our tallest and handsomest fern, often six 

 feet high. Probably more of this fern is used in cultivation in 

 our region than any other. 



WOODSIA R. Br. 



W. Ilvensis (L. ) R. Br. Rusty Polypod. Exposed rocks, sum- 

 mit of Mt. Markham, Unadilla Forks, Brown. The only station. 



W. obtusa (Spreng. ) Tprr. Obtuse Woodsia. Rare. Found 

 occasionally on the rocky walls along the Susquehanna below 

 Towanda, Clute. Elsewhere not reported. In aspect this is 

 much like Cystopteris fragilis, and at first glance might be 

 mistaken for that species. 



DICKSONIA L'Her. 



D. punctilobula (Michx ) A. Gray Hay Scented Fern. Fine- 

 Haired Mountain Fern. Plentiful. Found in open woods and 

 thickets especially in uplands. Fronds two or three feet long, 

 very finely cut, usually growing in dense patches. Some of the 

 higher elevations in our region are so thickly covered with this 

 species, that it excludes everything else. In the upland pastures, 

 its favorite habitat is under the edges of boulders, and the 

 peculiar green of its fronds is noticeable from a great distance. 

 Fragrant in drying. (D. pilosiuscula Willd. ) 



LYGODIUM Sw. 



L. palmatum (Bernh.) Sw. Climbing Fern. "McDonough, 

 Chenango county {Mrs. D B. Fitch. ) This is the second station 

 in which this fern has been found in our State." — Annual Re- 

 port State Botanist, jSgj. 



OSMUNDA L. 



O. regalia L. Flowering Fern. Royal Fern. Plentiful in 

 swamps and wet, open woodlands, often growing in shallow 

 water. Fronds very smooth, twice pinnate, the pinnules oblong. 

 Fruit borne in a panicle at the summit of some of the fronds. 

 An elegant species, much less like the popular conception of a 

 fern than most of our common species. 



O. Claytoniana L. Interrupted Flowering Fern. Clayton's 

 Fern. Common in low grounds, especially in thickets along 

 streams. Sterile fronds once pinnate, the pinnae pinnatifid.
