WOODSIA. 



W. llvensis, B. Br. — Frond lanceolate, usually four or five inches 

 long, bipinnate, or nearly so, pinnae approximate, pinnules oblong, 

 obtuse, stipe (red), rachis and whole lower surface of the frond 

 clothed with chaffy scales, which are rusty at maturity. Sori 

 usually confluent around the margins of the pinnules. First 

 observed in the Isle of Elba (Ilva), hence named, after Dale- 

 champ, Acrostichum I/vense by Linnaeus, whose Phoenix was 

 very wroth thereat; see English Flora, vol. iv, p. 323. Woodsia 

 Ilvensis, B. Br., Hook., Moore, J. Sm., Gray, &c. Nephrodium 

 lanosum, Michx. — Abundant on the ridge of Laurentian rocks at 

 Kingston Mills ; Rocks west from Brockville and at Chelsea, B. 

 Billings, jun. ; Mount Johnson and Beloeil Mountain, P. W. 

 Maclagan, M.D.; mountain gneiss rocks, opposite Bouge Biver, 

 W. S. M. D'Urban. I have likewise specimens from the Hudson 

 Bay territories (Governor M'Tavish), but without special locality.

 B. A. ; foot of Cape Tourmente, Abbe Provancher. I think 

 our plant must be much larger and more scaly than the European 

 one. A tuft which I have from Catskill Mountains (A. 0. Bro- 

 die) has richly fruited fronds a foot long and two inches wide. 

 (I find that large American forms of this species have been mis- 

 taken for W. obtusa. The involucre, which is large and not split 

 into hairs in the latter species, serves readily to distinguish it.) 

 Much of the W. Iloensis in cultivation in Europe is probably the 

 American form. 



/5- gracilis. — Frond more slender, more hairy and less scaly 

 than the type ; pinnae rather distant, deeply pinnatifid, or par-
