,:278 . THE CANADIAN NATURALIST. [^^g« 



y. rhneficum. — Frond rather small, firm, narrowly lanceolate 

 in outline ; pinse more or le~s distant and narrowly lanceolate ; 

 pinnules incisely toothed or deeply pinnatifid, linear, or more fre- 

 quently lanceolate-acute, and acquiring a linear aspect from the 

 reflection of the lobes, often crowded with confluent sori. — Dr. 

 Yates's farm, on the banks of the St. Lawrence, near Kingston ; 

 - near Montreal, Rev. E. M. Epstein, M.D.; near Lakefield, North 

 Douro, Mrs Traill. 



S. rtgidum. — Frond small, rigid; pinnules approximate, con- 

 nected at the base by a broad decurrent membrane, sori confined 

 to the lower part of each pinnule. — Lakefield, North Douro, Mrs. 

 Traill. 



There are other forms of this species, dependent in many cases, 

 no doubt, upon situation ; some with thin veiny fronds of great 

 size, bearing few scattered sori. One form, very like the British 

 var. moUe, was gathered at Belleville by Mr. Macoun. I know no 

 fern more variable than this. Our Canadian forms require careful 

 examination. 



WOODWARDIA. 



W. Virginica, Willd. — Frond pinnate ; pinnae lanceolate, pin- 

 natifid ; sori arranged in line on either side of the midribs of 

 pinnae and pinnules. Woodicardia Virginica, Willd. ; Gray 

 Man., p. 593. (Doodia, R, Br.) — Millgrove Marsh, C. W., Judge
